 The best action that audit management should consider first is to reassign the audit to an internal audit subject matter expert. This is because cloud service audits require specialized knowledge and skills to assess the risks and controls associated with the cloud service provider and the cloud service customer. An IS auditor who is unfamiliar with the technologies in use and their associated risks to the business may not be able to perform an effective and efficient audit, and may miss important issues or provide inaccurate recommendations. Therefore, it is important to ensure that the IS auditor assigned to the cloud service audit has the appropriate competence and experience.

The other options are not as good as reassigning the audit to an internal audit subject matter expert. Conducting a follow-up audit after a suitable period has elapsed may not address the quality issues of the initial audit, and may also delay the identification and remediation of any problems. Rescheduling the audit assignment for the next financial year may expose the organization to unnecessary risks and may not meet the audit objectives or expectations. Extending the duration of the audit to give the auditor more time may not be feasible or cost-effective, and may not guarantee that the auditor will acquire the necessary knowledge and skills in time.

The business owner is the person or entity that has the authority and responsibility for defining the purpose and scope of the processing of personal data, as well as the expected outcomes and benefits. The business owner is also accountable for ensuring that the processing of personal data complies with the applicable laws and regulations, such as the General Data Protection Regulation (GDPR) or the Data Protection Act 2018 (DPA 2018).

One of the requirements of the GDPR and the DPA 2018 is to adhere to the principle of storage limitation, which states that personal data should be kept for no longer than is necessary for the purposes for which it is processed1. This means that the business owner should determine and justify how long they need to retain personal data, based on factors such as:

The nature and sensitivity of the personal data

The legal or contractual obligations or rights that apply to the personal data

The business or operational needs and expectations that depend on the personal data

The risks and impacts that may arise from retaining or deleting the personal data

The business owner should also establish and document the conditions and methods for the destruction of personal data, such as:

The criteria and triggers for deciding when to destroy personal data

The procedures and tools for securely erasing or anonymising personal data

The roles and responsibilities for carrying out and overseeing the destruction of personal data

The records and reports for verifying and evidencing the destruction of personal data

Therefore, retention periods and conditions for the destruction of personal data should be determined by the business owner, as they are in charge of defining and managing the processing of personal data, as well as ensuring its compliance with the law.

To detect unauthorized disclosure of confidential documents sent over corporate email, monitoring all emails based on pre-defined criteria is the best approach. This involves setting up automated monitoring systems that analyze email content, attachments, and metadata to identify any potential unauthorized disclosures. By defining specific criteria (such as keywords related to confidential information), organizations can proactively detect and prevent leaks. Requiring encryption before sending documents (option A) is important but does not address monitoring for unauthorized disclosures. Firewalls (option B) protect the network but do not specifically focus on email content. Reporting outgoing emails marked as confidential (option C) relies onuser self-reporting and may not catch all

The most important thing to include in security awareness training is how to respond to various types of suspicious activity. Security awareness training is a program that educates employees about the importance of security and how to avoid common threats and risks. One of the main objectives of security awareness training is to enable employees to recognize and report any signs of malicious or unauthorized activity, such as phishing emails, malware infections, data breaches, or social engineering attempts. By teaching employees how to respond to various types of suspicious activity, security awareness training can help to prevent or mitigate the impact of security incidents, protect the organization’s assets and reputation, and comply with legal and regulatory requirements.

The other options are not as important as option A. The importance of complex passwords is a useful topic, but not the most important thing to include in security awareness training. Complex passwords are passwords that are hard to guess or crack by using a combination of letters, numbers, symbols, and cases. Complex passwords can help to protect user accounts and data from unauthorized access, but they are not sufficient to prevent all types of security incidents. Moreover, complex passwords may be difficult to remember or manage by users, and may require additional measures such as password managers or multi-factor authentication. Descriptions of the organization’s security infrastructure is a technical topic, but not the most important thing to include in security awareness training. Security infrastructure is the set of hardware, software, policies, and procedures that provide the foundation for the organization’s security posture and capabilities. Security infrastructure may include firewalls, antivirus software, encryption tools, access control systems, backup systems, etc. Descriptions of the organization’s security infrastructure may be relevant for some employees who are involved in security operations or administration, but they may not be necessary or understandable for all employees who need security awareness training. Contact information for the organization’s security team is a practical detail, but not the most important thing to include in security awareness training. Security team is the group of people who are responsible for planning, implementing, monitoring, and improving the organization’s security strategy and activities. Contact information for the organization’s security team may be useful for employees who need to report or escalate a security issue or request a security service or support. However, contact information for the organization’s security team is not enough to ensure that employees know how to respond to various types of suspicious activity. References: Security Awareness Training | SANS Security Awareness, Security AwarenessTraining | KnowBe4, SecurityAwareness Training Course (ISC)² | Coursera

 Control totals are a method of verifying the accuracy and completeness of data processing by comparing the totals of key fields in input and output records1. Control totals can be used to reduce the risk of incomplete processing, which is the failure to process all the data or transactions that are expected or required2.

Incomplete processing can result in data loss, inconsistency, or incompleteness, which can affect the quality and reliability of the information system and its outputs. Incomplete processing can be caused by various factors, such as:

Hardware or software failures that interrupt the processing or transmission of data2

Human errors or omissions that skip or miss some data or transactions2

Malicious attacks or unauthorized access that delete or modify some data or transactions2

Environmental hazards or disasters that damage or destroy some data or transactions2

Control totals can help detect and prevent incomplete processing by:

Providing a benchmark or reference point to compare the input and output data or transactions1

Identifying any discrepancies or deviations from the expected or required totals1

Alerting the users or operators to investigate and resolve the causes of incomplete processing1

Ensuring that all the data or transactions are properly transmitted, converted, and processed1

The other options are not as relevant as control totals for reducing the risk of incomplete processing. Posting to the wrong record is the error of assigning or transferring data or transactions to an incorrect account, file, or record3. Improper backup is the failure to create, store, or restore copies of data or transactions in case of loss, corruption, or damage4. Improper authorization is the lack of proper permission or approval to access, modify,or process data or transactions. Control totals may not be able to prevent or detect these errors or failures, as they are not related to the completeness of data processing. Therefore, option B is the correct answer.

Aligning IT strategy with business strategy primarily helps an organization to optimize investments in IT. This is because alignment ensures that IT resources and capabilities are aligned with the business goals and priorities, and that IT delivers value to the business in terms of efficiency, effectiveness, innovation, and competitive advantage12. By aligning IT strategy with business strategy, an organization can avoid wasting money and time on IT projects or services that do not support or contribute to the business outcomes3. Alignment also helps to identify and prioritize the most critical and valuable IT initiatives that can create or optimize business value4.

Therefore, the correct answer to your question is A. optimize investments in IT.

Validation checks are a type of data quality control that helps to ensure the integrity of data for a system interface. Validation checks verify that the data entered or transferred between systems is correct, consistent, and conforms to predefined rules or standards. Validation checks can prevent or detect errors, anomalies, or inconsistencies in the data that may affect the system’s functionality, performance, or security.

Option C is correct because validation checks are a common and effective method of ensuring data integrity for a system interface. Validation checks can be performed at various stages of the data lifecycle, such as input, processing, output, or storage. Validation checks can also be applied to different types of data, such as data types, codes, ranges, formats, consistency, and uniqueness.

Option A is incorrect because system interface testing is a type of software testing that verifies the interaction between two separate systems or components of a system. System interface testing does not directly ensure the integrity of data for a system interface, but rather the functionality and reliability of the interface itself. System interface testing may use validation checks as part of its test cases, but it is not the same as validation checks.

Option B is incorrect because user acceptance testing (UAT) is a type of software testing that evaluates whether the system meets the user’s expectations and requirements. UAT does not directly ensure the integrity of data for a system interface, but rather the usability and acceptability of the system from the user’s perspective. UAT may use validation checks as part of its test scenarios, but it is not the same as validation checks.

Option D is incorrect because audit logs are records of events and activities that occur within a system or network. Audit logs do not directly ensure the integrity of data for a system interface, but rather provide evidence and accountability for the system’s operations and security. Audit logs may use validation checks as part of their analysis or reporting, but they are not the same as validation checks.

The best recommendation to address the problem of missing IT deadlines on important projects because IT resources are not prioritized properly is to implement project portfolio management (PPM). PPM is the process of analyzing and optimizing the costs, resources, technologies, and processes for all the projects and programs within a portfolio. A portfolio is a collection of projects, programs, and processes that are managed together and aligned with the strategic goals and objectives of the organization. PPM can help the organization to:

Prioritize the most valuable and relevant projects and programs based on their alignment with the organizational strategy, vision, and mission.

Balance the portfolio to ensure that the projects and programs are diversified, feasible, and sustainable, and that they meet the needs and expectations of the stakeholders.

Optimize the allocation, utilization, and coordination of IT resources across the portfolio, such as staff, budget, time, equipment, and software.

Monitor and control the performance and progress of the projects and programs within the portfolio, and evaluate their outcomes and benefits.

By implementing PPM, the organization can improve its IT project delivery and avoid missing deadlines. PPM can also help the organization to increase its efficiency, effectiveness, quality, and value. For more information about PPM, you can refer to the following web search results:

PPM 101: What Is Project Portfolio Management?3

The third-party contract has not been reviewed by the legal department is the auditor’s greatest concern because it poses a significant legal and financial risk to the client. A third-party contract is a legally binding agreement between the client and the outsourced payroll provider that defines the scope, terms, and conditions of the service. A third-party contract should be reviewed by the legal department to ensure that it complies with the applicable laws and regulations, protects the client’s interests and rights, and specifies the roles and responsibilities of both parties. A third-party contract that has not been reviewed by the legal department may contain clauses that are unfavorable, ambiguous, or contradictory to the client, such as:

Inadequate or unclear service level agreements (SLAs) that do not specify the quality, timeliness, and accuracy of the payroll service.

Insufficient or vague security and confidentiality provisions that do not safeguard the client’s data and information from unauthorized access, use, disclosure, or loss.

Unreasonable or excessive fees, penalties, or liabilities that may impose an undue financial burden on the client.

Limited or no audit rights that may prevent the client from verifying the effectiveness and compliance of the payroll provider’s internal controls.

Inflexible or restrictive termination clauses that may limit the client’s ability to cancel or switch to another payroll provider.

A third-party contract that has not been reviewed by the legal department may expose the client to various risks, such as:

Legal disputes or litigation with the payroll provider over contractual breaches or performance issues.

Regulatory fines or sanctions for noncompliance with tax, labor, or other laws and regulations related to payroll.

Financial losses or damages due to errors, fraud, or negligence by the payroll provider.

Reputation damage or customer dissatisfaction due to payroll errors or delays.

Therefore, an IS auditor should be highly concerned about a third-party contract that has not been reviewed by the legal department and recommend that the client seek legal advice before signing or renewing any contract with an outsourced payroll provider.

User access rights have not been periodically reviewed by the client is a moderate concern because it may indicate a lack of proper access control over the payroll system. User access rights are the permissions granted to users to access, view, modify, or delete data and information in the payroll system. User access rights should be periodically reviewed by the client to ensure that they are aligned with the user’s roles and responsibilities, and that they are revoked or modified when a user changes roles or leaves the organization. User access rights that are not periodically reviewed by the client may result in unauthorized or inappropriate access to payroll data and information, which may compromise its confidentiality, integrity, and availability.

Payroll processing costs have not been included in the IT budget is a minor concern because it may indicate a lack of proper planning and allocation of IT resources for payroll processing. Payroll processing costs are the expenses incurred by the client for using an outsourced payroll service, such as fees, charges, taxes, or penalties. Payroll processing costs should be included in the IT budget to ensure that they are adequately estimated, monitored, and controlled. Payroll processing costs that are not included in the IT budget may result in unexpected or excessive costs for payroll processing, which may affect the client’s profitability and cash flow.

The third-party contract does not comply with the vendor management policy is a low concern because it may indicate a lack of alignment between the client’s vendor management policy and its actual vendor selection and evaluation process. A vendor management policy is a set of guidelines and procedures that governs how the client manages its relationship with its vendors, such as how to select, monitor, evaluate, and terminate vendors. A vendor management policy should be consistent with the client’s business objectives, risk appetite, and regulatory requirements. A third-party contract that does not comply with the vendor management policy may result in suboptimal vendor performance or service quality, but it does not necessarily imply a breach of contract or a violation of law.

 The record-locking option of a database management system (DBMS) serves to eliminate the risk of concurrent updates to a record by different users or transactions. Record locking is a technique of preventing simultaneous access to data in a database, to prevent inconsistent results1. For example, if two bank clerks try to update the same bank account for two different transactions, record locking can ensure that only one clerk can modify the record at a time, while the other has to wait until the lock is released. This way, the record will reflect both transactions correctly and avoid data corruption.

Record locking does not serve to allow database administrators (DBAs) to record the activities of users. This is a function of auditing or logging, which can track the actions performed by users on the database2. Record locking does not affect the ability of DBAs to monitor or audit user activities.

Record locking does not serve to restrict users from changing certain values within records. This is a function of access control or authorization, which can enforce rules or policies on what data users can view or modify2. Record locking does not affect the permissions or privileges of users on the database.

Record locking does not serve to allow users to lock others out of their files. This is a function of encryption or password protection, which can secure files from unauthorized access or modification3. Record locking does not affect the security or confidentiality of files on the database.

The first step when creating a data classification program is to develop a policy (D). A data classification policy is a document that defines the purpose, scope, objectives, roles, responsibilities, and procedures of the data classification program. A data classification policy is essential for establishing the governance framework, standards, and guidelines for the data classification process. A data classification policy also helps to communicate the expectations and benefits of the data classification program to the stakeholders, such as data owners, users, custodians, and auditors12.

Categorizing and prioritizing data (A) is not the first step when creating a data classification program, but the third step. Categorizing and prioritizing data involves defining and applying the criteria and labels for classifying data based on its sensitivity, value, and risk. For example, data can be categorized into public, internal, confidential, or restricted levels. Categorizing and prioritizing data helps to identify and protect the most critical and sensitive data assets of the organization12.

Developing data process maps (B) is not the first step when creating a data classification program, but the fourth step. Developing data process maps involves documenting and analyzing the flow and lifecycle of data within the organization. Data process maps show how data is created, collected, stored, processed, transmitted, used, shared, archived, and disposed of. Developing data process maps helps to understand the context and dependencies of data, as well as to identify and mitigate any potential risks or issues related to data quality, security, or compliance12.

Categorizing information by owner © is not the first step when creating a data classification program, but the second step. Categorizing information by owner involves assigning roles and responsibilities for each type of data based on its ownership and stewardship. Data owners are the individuals or entities that have the authority and accountability for the data. Data stewards are the individuals or entities that have the operational responsibility for managing and maintaining the data. Data custodians are the individuals or entities that have the technical responsibility for implementing and enforcing the security and access controls for the data12.

The sampling method in which the entire sample is considered to be irregular if a single error is found is discovery sampling. Discovery sampling is a type of statistical sampling that is used to test for the existence of at least one occurrence of a specific characteristic or condition in a population. Discovery sampling is often used when the auditor expects the characteristic or condition to be very rare or nonexistent, and when any occurrence would have a significant impact on the audit objective. For example, discovery sampling can be used to test for fraud, noncompliance, or material misstatement.

Discovery sampling works by setting a very low tolerable error rate (the maximum rate of occurrence of the characteristic or condition that the auditor is willing to accept) and a high confidence level (the degree of assurance that the auditor wants to obtain). The auditor then selects a sample from the population using a random or systematic method, and examines each item in the sample for the presence or absence of the characteristic or condition. If no error is found in the sample, the auditor can conclude with a high level of confidence that the characteristic or condition does not exist or is very rare in the population. However, if one or more errors are found in the sample, the auditor cannot draw any conclusion about the population and must either expand the sample size or perform alternative procedures.

Discovery sampling differs from other sampling methods in that it does not allow for any errors in the sample. Other sampling methods, such as variable sampling, stop-or-go sampling, or judgmental sampling, can tolerate some errors in the sample and use them to estimate the error rate or amount in the population. However, discovery sampling is designed to test for zero-tolerance situations, where any error would be unacceptable or material. Therefore, discovery sampling considers the entire sample to be irregular if a single error is found.

The IS audit standard for proficiency states that the IS auditor must have the knowledge, skills and experience needed to perform the audit work. This implies that the IS auditor must be competent in both the technical and business aspects of the audit subject matter. Therefore, team member assignments must be based on individual competencies, so that each auditor can perform the tasks that match their qualifications and expertise. This will also ensure that the audit objectives are met and the audit quality is maintained.

Option B is incorrect because technical co-sourcing is not a requirement to meet the IS audit standard for proficiency. Co-sourcing is an option that may be used when the internal audit function lacks the necessary resources or skills to perform the audit work. However, co-sourcing does not guarantee that the new staff will acquire the proficiency needed for the audit. Moreover, co-sourcing may introduce additional risks and challenges, such as confidentiality, independence, communication and coordination issues.

Option C is incorrect because having a globally recognized audit certification does not necessarily mean that the standard for proficiency is met. A certification is an indication of the auditor’s knowledge and competence in a specific domain, but it does not cover all aspects of IS auditing. The auditor must also have relevant experience and continuous learning to maintain and enhance their proficiency. Furthermore, having one certified member does not ensure that the other members are also proficient.

Option D is incorrect because having a supervisor review the new auditors’ work is not sufficient to meet the IS audit standard for proficiency. A supervisor review is a quality assurance measure that helps to ensure that the audit work is performed in accordance with the standards and policies. However, a supervisor review does not substitute for the proficiency of the auditors who perform the work. The auditors must still have the necessary knowledge, skills and experience to conduct the audit tasks effectively and efficiently.

The most effective method for detecting the presence of an unauthorized wireless access point on an internal network is A. Continuous network monitoring. This is because continuous network monitoring can capture and analyze all the wireless traffic in the network and identify any rogue or spoofed devices that may be connected to the network without authorization. Continuous network monitoring can also alert the system administrator of any suspicious or anomalous activities on the network and help to locate and remove the unauthorized wireless access point quickly.

Periodic network vulnerability assessments (B) can also help to detect unauthorized wireless access points, but they are not as effective as continuous network monitoring, because they are performed at fixed intervals and may miss some devices that are added or removed between the assessments. Review of electronic access logs © can provide some information about the devices that access the network, but they may not be able to detect devices that use fake or stolen credentials or devices that do not generate any logs. Physical security reviews (D) can help to prevent unauthorized physical access to the network ports or devices, but they may not be able to detect wireless access points that are hidden or disguised as legitimate devices.

The most significant risk when an application uses individual end-user accounts to access the underlying database is that users may be able to circumvent application controls. Application controls are the policies, procedures, and mechanisms that ensure the accuracy, completeness, validity, and authorization of transactions and data within an application. Application controls can include input validation, output verification, processing logic, reconciliation, exception handling, and audit trails. Application controls can help prevent or detect errors, fraud, or unauthorized access or modification of data.

However, if an application uses individual end-user accounts to access the underlying database, it means that the users have direct access to the database without going through the application layer. This can expose the database to potential risks such as:

Users may be able to bypass the application controls and manipulate the data in the database directly using SQL commands or other tools. For example, users may be able to change their own or others’ salaries, grades, or balances without proper authorization or validation.

Users may be able to access or disclose sensitive or confidential data that they are not supposed to see or share. For example, users may be able to view other users’ personal information, passwords, or credit card numbers.

Users may be able to introduce errors or inconsistencies in the data by entering invalid or incorrect data or by deleting or modifying existing data. For example, users may be able to create duplicate records, break referential integrity, or cause data loss or corruption.

Users may be able to compromise the security and performance of the database by creating unauthorized objects, granting excessive privileges, executing malicious code, or consuming excessive resources. For example, users may be able to create backdoors, viruses, or denial-of-service attacks.

Therefore, using individual end-user accounts to access the underlying database can pose a serious threat to the integrity, confidentiality, availability, and reliability of the data and the application.

The other options are not as significant as option C. Multiple connects to the database are used and slow the process is a performance issue that can affect the efficiency and responsiveness of the application and the database, but it does not necessarily compromise the data quality or security. User accounts may remain active after a termination is a security issue that can increase the risk of unauthorized access or misuse of data by former employees or others who have access to their credentials, but it can be mitigated by implementing proper account management and monitoring processes. Application may not capture a complete audit trail is a compliance issue that can affect the accountability and traceability of transactions and data within the application and the database, but it does not directly affect the data accuracy or protection.

Data classification is the process of tagging data according to its type, sensitivity, and value to the organization. Data transformation is the process of changing the structure and format of data to make it usable for analysis and visualization. Both processes are important for data security and compliance, but they also pose some challenges.

One of the challenges is to ensure that the organization’s data classification policies are preserved during the process of data transformation. This means that the data should retain its original classification level and labels after it is transformed, and that the appropriate controls and protections are applied to the transformed data.

The best way to ensure this is to implement classification labels in metadata during data creation (D). Metadata is data that describes other data, such as its source, format, content, and context. By adding classification labels to metadata, the data can be easily identified and tracked throughout its lifecycle, including during data transformation. The labels can also help enforce the proper access rights and encryption standards for the data, regardless of its state or location.

The best way to evaluate the effectiveness of a newly developed application is to review acceptance testing results. Acceptance testing is a process of verifying that the application meets the specified requirements and expectations of the users and stakeholders. Acceptance testing results can provide evidence of the functionality, usability, reliability, performance, security and quality of the application. Performing a post-implementation review, analyzing load testing results, and performing a secure code review are also important activities for evaluating an application, but they are not as comprehensive or conclusive as acceptance testing results.

Tabletop exercises are a type of simulation used to test an organization’s incident response plan12. They involve key stakeholders in a hypothetical scenario to see how they would respond12. This allows management to assess the effectiveness of the incident response process and identify areas for improvement12. Regularly conducting these exercises ensures that the organization is prepared for a real incident and that the incident response process remains effective over time12.

 Implementing solutions to correct defects is a responsibility of the development function, not the quality assurance (QA) function. The QA function should ensure that the development process follows the established standards and methodologies, and that the defects are identified and reported. The QA function should not be involved in fixing the defects, as this would compromise its independence and objectivity. The other options are valid responsibilities of the QA function, and they should not raise concern for an IS auditor. References: CISA Review Manual (Digital Version) 1, page 300.

The role of a document owner when implementing a data classification policy in an organization is to classify documents to correctly reflect the level of sensitivity of information they contain. A document owner is the person who is ultimately responsible for the creation, maintenance, and protection of a document, usually a member of senior management or a business unit1. A data classification policy is a plan that defines how the organization categorizesits data based on its value, risk, and regulatory requirements, and how it handles and secures each data category2.

According to the data classification policy template by Netwrix3, one of the roles and responsibilities of the document owner is to assign data classification labels based on the data’s potential impact level. Data classification labels are tags or markings that indicate the sensitivity level of the data, such as public, internal, confidential, or restricted. The document owner should apply the data classification labels to the documents that contain the data, either manually or automatically, using tools and methods such as metadata, watermarks, headers, footers, or encryption. The document owner should also review and update the data classification labels periodically or whenever there is a change in the data’s sensitivity level.

By classifying documents to correctly reflect the level of sensitivity of information they contain, the document owner can help to ensure that the documents are handled in accordance with the data classification policy. This means that the documents are stored, accessed, shared, transmitted, and disposed of in a secure and appropriate manner, based on the rules and controls defined for each data category. This can also help to prevent data loss, leakage, or breach incidents that may cause harm or damage to the organization or its stakeholders.

Therefore, option A is the correct answer.

The missing access control requirements should present the greatest concern to the IS auditor when reviewing a contract for the outsourcing of IT facilities. Access control requirements are essential for ensuring the confidentiality, integrity, and availability of the outsourced IT resources and data. They specify the roles, responsibilities, and permissions of the outsourcing vendor and its staff, as well as the client and its users, in accessing and managing the IT facilities. They also define the security policies, standards, and procedures that the outsourcing vendor must follow to protect the IT facilities from unauthorized or malicious access, use, modification, or disclosure. Without clear and comprehensive access control requirements, the outsourcing contract may expose the client to significant risks of data breaches, compliance violations, service disruptions, or reputational damage.

Hardware configurations, help desk availability, and perimeter network security diagram are important aspects of an outsourcing contract, but they are not as critical as access control requirements. Hardware configurations describe the technical specifications and performance of the IT equipment that the outsourcing vendor will provide and maintain. Help desk availability defines the service levels and support channels that the outsourcing vendor will offer to the client and its users. Perimeter network security diagram illustrates the network architecture and security measures that the outsourcing vendor will implement to protect the IT facilities from external threats. These aspects can be verified or modified during the implementation or operation phases of the outsourcing contract, but access control requirements need to be established and agreed upon before signing the contract.

Conducting periodic testing and incorporating lessons learned is the best way to improve the effectiveness of an incident response team. This allows the team to practice their response procedures, identify any gaps or weaknesses in their response, and learn from their mistakes. It also helps to keep the team’s skills sharp and up-to-date. The lessons learned from these tests can then be used to improve the team’s procedures and performance12. While understanding information systems technology, disseminating incident response procedures, and publishing KPI metrics can contribute to the effectiveness of the team, they do not provide the same level of continuous improvement as periodic testing and learning from experience.

If the audit team lacks the necessary knowledge to audit a system that uses an AI algorithm, engaging external consultants who have audit experience and knowledge of AI would be the best approach12. These consultants can provide the expertise needed to effectively audit the AI system12. This approach ensures that the audit is conducted thoroughly and accurately, without requiring the audit team to acquire new skills or knowledge12.

A post-implementation review (PIR) is a process to evaluate whetherthe objectives of the project were met, determine how effectively this wasachieved, learn lessons for the future, and ensure that the organisation gets the most benefit from the implementation of projects1. A PIR is an important tool for assessing the success and value of a project, as well as identifying the areas for improvement and best practices for future projects.

One of the key elements of a PIR is to measure the benefits of the project against the expected outcomes and benefits that were defined at the beginning of the project. Measurable benefits are the quantifiable and verifiable results or outcomes that the project delivers to theorganisation or its stakeholders, such as increased revenue, reduced costs, improved quality, enhanced customer satisfaction, or compliance with regulations2. Measurable benefits should be aligned with the organisation’s strategy, vision, and goals, and should be SMART (specific, measurable, achievable, relevant, and time-bound).

The finding that measurable benefits were not defined is of greatest significance among the four findings, because it implies that:

The project did not have a clear and agreed-upon purpose, scope, objectives, and deliverables

The project did not have a valid and realistic business case or justification for its initiation and implementation

The project did not have a robust and effective monitoring and evaluation mechanism to track its progress, performance, and impact

The project did not have a reliable and transparent way to demonstrate its value proposition and return on investment to the organisation or its stakeholders

The project did not have a meaningful and actionable way to learn from its achievements and challenges, and to improve its processes and practices

Therefore, an IS auditor should recommend that measurable benefits are defined for any project before its implementation, and that they are reviewed and reported regularly during and after the project’s completion.

The other possible findings are:

A lessons-learned session was never conducted: This is a significant finding, but not as significant as the lack of measurable benefits. A lessons-learned session is a process of capturing and documenting the knowledge, experience, and feedback gained from a project, both positive and negative. A lessons-learned session helps to identify the strengths and weaknesses of the project management process, as well as the best practices and lessons for future projects. A lessons-learned session should be conducted at the end of each project phase or milestone, as well as at the end of the project. However, even without a formal lessons-learned session, some learning may still occur informally or implicitly among the project team members or stakeholders.

The projects 10% budget overrun was not reported to senior management: This is a significant finding, but not as significant as the lack of measurable benefits. A budget overrun is a situation where the actual cost of a project exceeds its planned or estimated cost. A budget overrun may indicate poor planning, estimation, or control of the project resources, or unexpected changes or risks that occurred during the project implementation. A budget overrun should be reported to senior management as soon as possible, along with the reasons for it and the corrective actions taken or proposed. However, a budget overrun may not necessarily affect the quality or value of the project deliverables or outcomes if they are still within acceptable standards or expectations.

Monthly dashboards did not always contain deliverables: This is a significant finding, but not as significant as the lack of measurable benefits. A dashboard is a visual tool that displays key performance indicators (KPIs) or metrics related to a project’s progress, status, or results. A dashboard helps to monitor and communicate the performance of a project to various stakeholders in a concise and clear manner. A dashboard should include deliverables as one of its components, along with other elements such as schedule, budget, quality, risks, issues, or benefits. However, even without deliverables in monthly dashboards, some information about them may still be available from other sources such as reports or documents.

The most important part of a feasibility study is the economics1. A cost-benefit analysis of available products is crucial as it helps to understand the economic viability of the project1. It compares the costs of the project with the benefits it is expected to deliver, which is essential for making informed decisions1. Omitting this could lead to investments in hardware that may not provide the expected returns or meet the organization’s needs.

This is because the business processes are the core activities and functions that enable the organization to achieve its objectives and create value for its stakeholders. The business processes are also the sources and drivers of various risks that may affect the organization’s performance, compliance, and reputation. Therefore, the IS auditor should focus on understanding, assessing, and prioritizing the business processes that are most critical, complex, or vulnerable to the organization’s success, and align the audit objectives, scope, and resources accordingly12.

Critical business applications (A) are not the most important area of focus for an IS auditor when developing a risk-based audit strategy, but rather a specific aspect of the business processes that may require attention. Critical business applications are the software systems that support the execution and automation of the business processes, such as enterprise resource planning (ERP), customer relationship management (CRM), or accounting systems. Critical business applications may pose significant risks to the organization if they are not reliable, secure, or efficient. Therefore, the IS auditor should consider the criticality, functionality, and dependency of the business applications when planning the audit, but not as the primary focus12.

Existing IT controls © are not the most important area of focus for an IS auditor when developing a risk-based audit strategy, but rather an outcome or output of the risk assessment process. Existing IT controls are the policies, procedures, practices, and technologies that are implemented to manage and mitigate the IT-related risks that may affect the organization’s business processes and objectives. Existing IT controls may vary in their design, effectiveness, and maturity. Therefore, the IS auditor should evaluate and testthe existing IT controls as part of the audit execution and reporting process, but not as the main focus12.

Recent audit results (D) are not the most important area of focus for an IS auditor when developing a risk-based audit strategy, but rather an input or source of information for the risk assessment process. Recent audit results are the findings, recommendations, and opinions of previous audits that may provide insights or feedback on the organization’s business processes, risks, and controls. Recent audit results may also indicate any changes or trends in the organization’s risk profile or environment. Therefore, the IS auditor should review and consider the recent audit results as part of the audit planning and scoping process, but not as the main focus12.

While all the options can help reduce the risk of data leakage, providing education and guidelines to employees on the use of social networking sites would be the most effective. This is because it directly addresses the issue at hand - the use of social networking sites for business purposes1. Education and guidelines can help employees understand the risks associated withsocial media use and teach them how to safely and responsibly use these platforms for business purposes1. This includes understanding privacy settings, recognizing phishing attempts, and knowing what information should not be shared on these platforms1.

The best option for the question is C, information owner. This is because:

The information owner is the person or entity that has the authority and responsibility for the business processes and functions that collect, use, store, and dispose of data1.

The information owner is accountable for ensuring that the data is handled in compliance with the applicable laws, regulations, policies, and standards, such as the GDPR and the PIPEDA1234.

The information owner is in the best position to determine the purpose and necessity of collecting and retaining data, as well as the risks and benefits associated with it1.

The information owner should consult with other stakeholders, such as the risk manager, the database administrator (DBA), and the privacy manager, to establish and implement appropriate data classification policies and procedures2.

Data classification is the process of organizing data in groups based on their attributes and characteristics, and then assigning class labels that describe a set of attributes that hold true for the corresponding data sets345.

Data classification helps organizations to identify, manage, protect, and understand their data, as well as to comply with modern data privacy regulations345.

Data classification also helps to determine appropriate user access levels, which means defining who can access, modify, share, or delete data based on their roles, responsibilities, and needs345.

Therefore, the information owner should be responsible for the data classification in an ERP migration project from local systems to the cloud (option C), as they have the authority and accountability for the data and its protection.

The other options are not correct because:

The information security officer (option A) is responsible for overseeing and coordinating the security policies and practices of the organization that involve data6. The information security officer should advise and assist the information owner on the best practices and standards for data security, but not determine the data classification.

The database administrator (DBA) (option B) is responsible for installing, configuring, monitoring, maintaining, and improving the performance of databases and data stores that contain data5. The DBA should support the information owner in implementing and enforcing the data classification policies and procedures, but not determine them.

The data architect (option D) is responsible for designing, modeling, and documenting the logical and physical structures of databases and data stores that contain data7. The data architect should collaborate with the information owner in creating and maintaining the data classification schema and metadata, but not determine them.

The primary benefit of a tabletop exercise for an incident response plan is to increase confidence in the team’s response readiness (D). A tabletop exercise is a simulated scenario that tests the effectiveness and efficiency of the incident response plan and team. It allows the team to practice their roles and responsibilities, review their procedures and tools, and identify and resolve any gaps or issues in their response process. A tabletop exercise can help the team to improve their skills, knowledge, and communication, and to prepare for real incidents1.

A full interruption test is the most realistic and reliable way to ensure that recovery time objectives (RTOs) are met for an organization’s disaster recovery plan (DRP). RTOs are the maximum amount of time that a business can tolerate being offline after a disaster. A full interruption test involves shutting down the primary site and switching over to the backup site, simulating a real disaster scenario. This test can measure the actual time it takes to restore the systems, applications, and functions that are critical for the business continuity. A full interruption test can also reveal any issues or gaps in the DRP that might affect the recovery process.

The other options are not as effective as a full interruption test for ensuring RTOs are met. A cyber resilience test is a type of DR test that focuses on the ability to withstand and recover from cyberattacks. It does not necessarily cover other types of disasters or test the entire DRP. A tabletop test is a low-impact DR test that involves a walkthrough of the DRP with the key stakeholders and staff. It does not involve any actual switching over or testing of the backup systems. A parallel test is a type of DR test that involves running the backup systems alongside the primary systems, without disrupting the normal operations. It does not measure the time it takes to switch over or resume operations at the backup site.

If an IS auditor suspects that independence may not have been maintained in past audits, the best course of action is to inform audit management. Audit management has the responsibility and authority to address such issues. They can review the situation, determine if there was indeed a lack of independence, and decide on the appropriate actions to take123. While informing senior management, reevaluating internal controls, and re-performing past audits might be necessary at some point, the first step should be to inform audit management.

Reviewing the application implementation documents is the best way for an IS auditor to assess the design of an automated application control. An automated application control is a control that is embedded in the application software and is executed by the system without human intervention. An automated application control is designed to ensure the accuracy, completeness, validity, and authorization of transactions and data processed by the application. Examples of automated application controls are input validation, edit checks, calculations, reconciliations, and exception reports.

The application implementation documents are the documents that describe the design specifications, logic, and functionality of the application and its controls. The application implementation documents may include:

Business requirements document - a document that defines the business objectives, needs, and expectations of the application.

Functional specifications document - a document that describes the features, functions, and interfaces of the application and its controls.

Technical specifications document - a document that details the technical architecture, design, and configuration of the application and its controls.

Test plan and test cases - a document that outlines the testing strategy, methodology, and scenarios for verifying the functionality and performance of the application and its controls.

User manual and training material - a document that provides instructions and guidance on how to use the application and its controls.

By reviewing the application implementation documents, an IS auditor can:

Gain an understanding of the purpose, scope, and nature of the application and its controls.

Evaluate whether the application and its controls are designed to meet the business requirements and objectives.

Identify any gaps, inconsistencies, or errors in the design of the application and its controls.

Compare the design of the application and its controls with the best practices and standards in the industry.

Determine whether the application and its controls are adequately tested and documented.

Interviewing the application developer is not the best way for an IS auditor to assess the design of an automated application control. An interview is a verbal communication technique that involves asking questions and listening to responses. An interview can be useful for obtaining general information or clarifying specific issues related to the application and its controls. However, an interview alone cannot provide sufficient evidence or documentation to support the auditor’s assessment of the design of an automated application control. An interview may also be subject to bias, misunderstanding, or misinterpretation by either party.

Obtaining management attestation and sign-off is not the best way for an IS auditor to assess the design of an automated application control. Management attestation and sign-off is a formal process that involves obtaining written confirmation from management that they have reviewed and approved the design of the application and its controls. Management attestation and sign-off can indicate management’s commitment and accountability for the quality and effectiveness of the application and its controls. However, management attestation and sign-off cannot substitute for an independent and objective evaluation by an IS auditor. Management attestation and sign-off may also be influenced by pressure, conflict of interest, or fraud.

Reviewing system configuration parameters and output is not the best way for an IS auditor to assess the design of an automated application control. System configuration parameters are settings that define how the system operates or interacts with other components. System output is data or information that is produced by the system as a result of processing transactions or performing functions. Reviewing system configuration parameters and output can help an IS auditor to verify whether the system is configured correctly and whether it produces accurate and reliable output. However, reviewing system configuration parameters and output cannot provide a comprehensive view of how the application and its controls are designed to achieve their objectives. Reviewing system configuration parameters and output may also require technical expertise or access rights that may not be available to an IS auditor.

Answer: A. Risk policies

Risk appetite is the amount and type of risk that an organization is willing to accept in pursuit of its objectives. Risk appetite reflects the organization’s risk culture, strategy, and tolerance, and guides the organization’s risk management practices. The most useful informationabout risk appetite can be obtained from the risk policies, which are the documents that define the organization’s risk management framework, principles, objectives, roles, responsibilities, and processes. Risk policies also establish the criteria and thresholds for identifying, assessing, prioritizing, mitigating, and monitoring risks, as well as the reporting and escalation mechanisms for risk issues. By reviewing the risk policies, an IS auditor can evaluate whether they are consistent, comprehensive, and aligned with the organization’s risk appetite and whether they provide clear guidance and direction for managing risks effectively.

The other options are not correct because they are either not the most useful or not relevant to risk appetite. Risk assessments are the processes of identifying, analyzing, and evaluating the risks that may affect the organization’s objectives. Risk assessments provide information about the current risk profile and exposure of the organization, but they do not indicate the organization’s risk appetite or preferences. Prior audit reports are the documents that summarize the findings, recommendations, and conclusions of previous audits. Prior audit reports may provide information about the past performance and issues of the organization’s risk management practices, but they do not reflect the organization’s risk appetite or expectations. Management assertion is a statement or declaration made by management about the accuracy, completeness, validity, or reliability of a certain fact or data. Management assertion may provide information about the management’s confidence or opinion on a specific risk or issue, but it does not represent the organization’s risk appetite or criteria.

Substantive testing © provides the best evidence of the validity and integrity of logs in an organization’s security information and event management (SIEM) system, because it is a type of audit testing that directly examines the accuracy, completeness, and reliability of the data and transactions recorded in the logs. Substantive testing can involve various methods, such as re-performance, inspection, observation, inquiry, or computer-assisted audit techniques (CAATs), to verify the existence, occurrence, valuation, ownership, presentation, and disclosure of the log data1. Substantive testing canalso detect any errors, omissions, alterations, or manipulations of the log data that may indicate fraud or misstatement2.

Compliance testing (A) is not the best evidence of the validity and integrity of logs in an organization’s SIEM system, because it is a type of audit testing that evaluates the design and effectiveness of the internal controls that are implemented to ensure compliance with laws, regulations, policies, and procedures. Compliance testing can involve various methods, such as walkthroughs, questionnaires, checklists, or flowcharts, to assess the adequacy, consistency, and operation of the internal controls1. Compliance testing can provide assurance that the log data are generated and processed in accordance with the established rules and standards, but it does not directly verify the accuracy and reliability of the log data itself2.

Stop-or-go sampling (B) is not a type of audit testing, but a type of sampling technique that auditors use to select a sample from a population for testing. Stop-or-go sampling is a sequential sampling technique that allows auditors to stop testing before reaching the predetermined sample size if the results are satisfactory or conclusive. Stop-or-go sampling can reduce the audit cost and time by avoiding unnecessary testing, but it can also increase the sampling risk and uncertainty by relying on a smaller sample3. Stop-or-go sampling does not provide any evidence of the validity and integrity of logs in an organization’s SIEM system by itself; it depends on the type and quality of the audit tests performed on the selected sample.

Variable sampling (D) is not a type of audit testing, but a type of sampling technique that auditors use to estimate a numerical characteristic of a population for testing. Variable sampling is a statistical sampling technique that allows auditors to measure the amount or rate of error or deviation in a population by using quantitative methods. Variable sampling can provide precise and objective results by using mathematical formulas and confidence intervals4. Variable sampling does not provide any evidence of the validity and integrity of logs in an organization’s SIEM system by itself; it depends on the type and quality of the audit tests performed on the selected sample.

Data migration is the process of moving data from one system to another, which may involve changes in storage, database, or application. To perform a successful data migration, it is essential to understand the data structure of the new system, which defines how the data is organized, stored, and accessed. Understanding the new system’s data structure will help determine the following aspects of the data migration project:

The scope and requirements of the data migration, such as what data needs to be migrated, how much data needs to be migrated, and what are the quality and performance expectations.

The data mapping and transformation rules, such as how the data elements from the source system correspond to the data elements in the target system, and what transformations or conversions are needed to ensure compatibility and consistency.

The data validation and testing methods, such as how to verify that the migrated data is accurate, complete, and functional in the new system, and how to identify and resolve any errors or issues.

Therefore, understanding the new system’s data structure is a crucial first step in a data migration project, as it lays the foundation for the subsequent steps of data extraction, transformation, loading, validation, and testing.

 The best option for ensuring confidentiality through the use of asymmetric encryption is to encrypt a message with the recipient’s public key (option A). This is because:

Asymmetric encryption, also known as public-key cryptography, is a type of encryption that uses a pair of keys to encrypt and decrypt data. The pair of keys includes a public key, which can be shared with anyone, and a private key, which is kept secret by the owner12.

In asymmetric encryption, the sender uses the recipient’s public key to encrypt the data. The recipient then uses their private key to decrypt the data. This approach allows for secure communication between two parties without the need for both parties to have the same secret key12.

Encrypting a message with the recipient’s public key ensures that only the recipient can decrypt it with their private key. This provides confidentiality, which means that the message is protected from unauthorized access or disclosure12.

Encrypting a message with the sender’s private key (option B) does not ensure confidentiality, but rather authentication, which means that the message can be verified as coming from the sender. This is because anyone can decrypt the message with the sender’s public key, but only the sender can encrypt it with their private key12.

Encrypting a message with the sender’s public key (option C) or the recipient’s private key (option D) does not make sense, as it would render the message unreadable by both parties. This is because neither party has the corresponding key to decrypt it12.

Therefore, the best option for ensuring confidentiality through the use of asymmetric encryption is to encrypt a message with the recipient’s public key (option A), as this ensures that only the recipient can decrypt it with their private key.

In the event of a disaster where the data center is no longer available, the first step should be to activate the call tree1. A call tree is a layered hierarchical communication model used to notify specific individuals of an event and coordinate recovery efforts1. This ensures that all relevant parties are informed about the situation and can begin executing their parts of the disaster recovery plan1.

Operating system parameters are settings or values that affect the behavior or performance of the operating system1. Modifications to the operating system parameters may be necessary to improve the system functionality, security, or efficiency. However, such modifications may also introduce risks or errors that can affect the system stability, compatibility, or integrity. Therefore, modifications to the operating system parameters should be authorized and documented by the appropriate authority2.

A change control log is a record of all changes made to the system, including the date, time, description, reason, authorization, and impact of each change3. A change control log can help the IS auditor to verify whether modifications to the operating system parameters were authorized by comparing the log entries with the actual system settings and the change approval documents4.

The best option that facilitates strategic program management is aligning projects with business portfolios (option C). This is because:

Strategic program management is the coordinated planning, management, and execution of multiple related projects that are directed toward the same strategic goals12.

Aligning projects with business portfolios means ensuring that the projects within a program are aligned with the organization’s strategic objectives, vision, and mission .

Aligning projects with business portfolios helps to prioritize the most valuable and impactful projects, optimize the allocation of resources, monitor the progress and performance of the program, and deliver the expected benefits and outcomes .

Implementing stage gates (option A) is a process of reviewing and approving projects at predefined points in their lifecycle to ensure that they meet the quality, scope, time, and cost criteria. While this can help to control and improve the project management process, it does not necessarily facilitate strategic program management, as it does not address the alignment of projects with business portfolios.

Establishing a quality assurance (QA) process (option B) is a process of ensuring that the project deliverables meet the quality standards and requirements of the stakeholders. While this can help to enhance the quality and satisfaction of the project outcomes, it does not necessarily facilitate strategic program management, as it does not address the alignment of projects with business portfolios.

Tracking key project milestones (option D) is a process of monitoring and reporting the completion of significant events or deliverables in a project. While this can help to measure and communicate the progress and status of the project, it does not necessarily facilitate strategic program management, as it does not address the alignment of projects with business portfolios.

Therefore, the best option that facilitates strategic program management is aligning projects with business portfolios (option C), as this ensures that the projects within a program are consistent with the organization’s strategic goals and objectives.

The effectiveness of a security awareness training program is best indicated by a reduction in unintentional violations. When employees are well-trained and aware of security practices, they are less likely to inadvertently violate security policies or make mistakes that could lead to breaches. While other factors (such as third-party social engineering tests, employee satisfaction, and completion rates) provide valuable insights, the ultimate goal of security awareness training is to minimize unintentional errors and improve overall security

The primary purpose of an incident response plan is to reduce the impact of an adverse event on information assets. An incident response plan is a set of instructions and procedures that guide the organization’s actions in the event of a security breach, cyberattack, or other disruption that affects its information systems and data. An incident response plan aims to:

Detect and identify the incident as soon as possible.

Contain and isolate the incident to prevent further damage or spread.

Analyze and investigate the incident to determine its cause, scope, and impact.

Eradicate and eliminate the incident and its root causes from the affected systems and data.

Recover and restore the normal operations and functionality of the systems and data.

Learn and improve from the incident by documenting the lessons learned, best practices, and recommendations for future prevention and mitigation.

By following an incident response plan, the organization can minimize the negative consequences of an adverse event on its information assets, such as:

Loss or corruption of data or information.

Disclosure or theft of confidential or sensitive data or information.

Interruption or degradation of system or service availability or performance.

Legal or regulatory noncompliance or liability.

Financial or reputational loss or damage.

An incident response plan also helps the organization to demonstrate its due diligence and accountability in protecting its information assets and complying with its legal and contractual obligations.

The other options are not the primary purpose of an incident response plan, although they may be secondary benefits or outcomes of having one.

Increasing the effectiveness of preventive controls is not the primary purpose of an incident response plan. Preventive controls are controls that aim to prevent or deter incidents from occurring in the first place, such as firewalls, antivirus software, encryption, authentication, etc. An incident response plan is a reactive control that deals with incidents after they have occurred. However, an incident response plan may help to improve the effectiveness of preventive controls by identifying and addressing their weaknesses or gaps.

Reducing the maximum tolerable downtime (MTD) of impacted systems is not the primary purpose of an incident response plan. MTD is a measure of how long an organization can tolerate a system or service outage before it causes unacceptable harm or loss to its business operations or objectives. An incident response plan may help to reduce the MTD of impacted systems by facilitating a faster and smoother recovery process. However, reducing the MTD is not the main goal of an incident response plan, but rather a desired outcome.

Increasing awareness of impacts from adverse events to IT systems is not the primary purpose of an incident response plan. Awareness is a state of being informed or conscious of something. An incident response plan may help to increase awareness of impacts from adverse events to IT systems by providing information and communication channels for stakeholders, such as management, employees, customers, regulators, etc. However, increasing awareness is not the main objective of an incident response plan, but rather a means to achieve other objectives, such as reducing impact, ensuring compliance, or maintaining trust.

A CO2 system could be a concern for an IS auditor when used to protect an asset storage closet. While CO2 systems are effective at suppressing fires, they can pose a significant safety risk to personnel. In the event of a fire,the CO2 system would fill the room with carbon dioxide, displacing the oxygen. This could be hazardous to anyone who might be in the room at the time12.

The most concerning thing for an IS auditor reviewing an IT strategy document is that the strategic IT goals are derived solely from the latest market trends. An IT strategy document is a blueprint that defines how an organization will use technology to achieve its goals. It should be based on a thorough analysis of the organization’s internal and external factors, such as its vision, mission, values, objectives, strengths, weaknesses, opportunities, threats, customers, competitors, regulations, and industry standards. An IT strategy document should also align with the organization’s business strategy and reflect its unique needs and capabilities. If an IT strategy document is derived solely from the latest market trends, it may not be relevant or appropriate for the organization’s specific situation. It may also lack coherence, consistency, feasibility, or sustainability.

The other options are not as concerning as option C. Target architecture is defined at a technical level is not a concern for an IS auditor reviewing an IT strategy document. Target architecture is the desired state of an organization’s IT systems in terms of their structure, functionality, performance, security, interoperability, and integration. Defining target architecture at a technical level can help an IS auditor to understand how the organization plans to achieve its strategic IT goals and what technical requirements and standards it needs to follow. The previous year’s IT strategic goals were not achieved is not a concern for an IS auditor reviewing an IT strategy document. The previous year’s IT strategic goals are the outcomes that the organization intended to accomplish with its IT initiatives in the past year. Not achieving these goals may indicate some challenges or gaps in the organization’s IT performance or execution. However, this does not necessarily affect the quality or validity of the current IT strategy document. An IS auditor should focus on evaluating whether the current IT strategy document is realistic, measurable, achievable, relevant, and time-bound. Financial estimates of new initiatives are disclosed within the document is not a concern for an IS auditor reviewing an IT strategy document. Financial estimates are projections of the costs and benefits of new initiatives that are part of the IT strategy document. Disclosing financial estimates within the document can help an IS auditor to assess whether the new initiatives are aligned with the organization’s budget and resources and whether they provide value for money. References: IT Strategy Template for a Successful Strategic Plan | Gartner, Definitive Guide to Developing anIT Strategy and Roadmap - CioPages, An Example of a Well-Developed IT Strategy Plan - Resolute

The first thing that an IS auditor should evaluate when reviewing an organization’s response to new privacy legislation is the analysis of systems that contain privacy components. Privacy components are elements of a system that collect, process, store, or transmit personal information that is subject to privacy legislation. An analysis of systems that contain privacy components should identify what types of personal information are involved, where they are located, how they are used, who has access to them, and what risks or threats they face. An analysis of systems that contain privacy components is essential for determining the scope and impact of the new privacy legislation on the organization’s systems and processes.

The other options are not as important as option D. An implementation plan for restricting the collection of personal information is a possible action, but not the first thing to evaluate, when reviewing an organization’s response to new privacy legislation. An implementation plan for restricting the collection of personal information is a document that outlines how an organization will comply with the principle of data minimization, which states that personal information should be collected only for specific and legitimate purposes and only to the extent necessary for those purposes. An implementation plan for restricting the collection of personal information should be based on an analysis of systems that contain privacy components. Privacy legislation in other countries that may contain similar requirements is a possible source of reference, but not the first thing to evaluate, when reviewing an organization’s response to new privacy legislation. Privacy legislation in other countries that may contain similar requirements is a set of laws or regulations that governs the protection of personal information in other jurisdictions that may have comparable or compatible standards or expectations as the new privacy legislation. Privacy legislation in other countries that may contain similar requirements may provide guidance or best practices for complying with the new privacy legislation. However, privacy legislation in other countries that may contain similar requirements should not be used as a substitute foran analysis of systems that contain privacy components. An operational plan for achieving compliance with the legislation is a possible deliverable, but not the first thing to evaluate, when reviewing an organization’s response to new privacy legislation. An operational plan for achieving compliance with the legislation is a document that describes how an organization will implement and maintain the necessary policies, procedures, controls, and measures to comply with the new privacy legislation. An operational plan for achieving compliance with the legislation should be derived from an analysis of systems that contain privacy components. References: Privacy law - Wikipedia, Data Protection and Privacy Legislation Worldwide | UNCTAD, Data minimization - Wikipedia

The NEXT step for the IS auditor after noting that an employee who has recently changed roles within the organization still has previous access rights should be to B. determine the reason why access rights have not been revoked. Identifying the cause of this situation is crucial for understanding whether it’s due to oversight, process gaps, or other factors. Once the reason is determined, appropriate corrective actions can be recommended to ensure that access rights are aligned with the employee’s current role and responsibilities1.

The organization’s software inventory is not complete. This finding would be of greatest concern to an IS auditor assessing an organization’s patch management process because:

A software inventory is a list of all the software assets that an organization owns, uses, or manages. A software inventory is essential for effective patch management, as it helps identify the software that needs to be updated, the patches that are available, and the dependencies and compatibility issues that may arise. Without a complete software inventory, an organization may miss some critical patches, expose itself to security risks, and waste resources on unnecessary or redundant patches.

Applications frequently need to be rebooted for patches to take effect. This finding would be of moderate concern to an IS auditor assessing an organization’s patch management process because:

Rebooting applications for patches to take effect is a common and expected practice in some cases, especially for operating system or kernel patches. However, frequent reboots may indicate that the organization is not applying patches in a timely or efficient manner, or that the patches are not well-designed or tested. Frequent reboots may also cause disruption to the business operations and user experience, and increase the risk of data loss or corruption.

Software vendors are bundling patches. This finding would be of low concern to an IS auditor assessing an organization’s patch management process because:

Bundling patches is a practice where software vendors combine multiple patches into a single package or update. Bundling patches can have some advantages, such as reducing the number of downloads and installations, simplifying the patch management process, and ensuring consistency and compatibility among patches. However, bundling patches can also have some disadvantages, such as increasing the size and complexity of the updates, delaying the delivery of critical patches, and introducing new bugs or vulnerabilities.

Testing patches takes significant time. This finding would be of low concern to an IS auditor assessing an organization’s patch management process because:

Testing patches is a vital step in the patch management process, as it helps ensure that the patches are functional, secure, and compatible with the existing software and hardware environment. Testing patches can take significant time, depending on the scope, complexity, and frequency of the patches. However, testing patches is a necessary investment to avoid potential problems or failures that could result from applying untested or faulty patches.

The primary reason an IS auditor should discuss observations with management before delivering a final report is A. Validate the audit observations. This is because discussing the observations with management can help the auditor to ensure that the findings are accurate, complete, and supported by sufficient evidence1. It can also help the auditor to obtain management’s perspective and feedback on the issues and risks identified, and to avoid any misunderstandings or surprises when the final report is issued2.

The correct answer is B. Management’s commitment to information security. Management’s commitment to information security is the most critical factor for the success of an information security program, as it provides the leadership, support, and resources needed to establish and maintain a secure environment. Management’s commitment to information security can be demonstrated by:

Setting the vision, mission, and goals for information security, and aligning them with the organization’s strategies and objectives1.

Establishing and enforcing the policies, standards, and procedures for information security, and ensuring compliance with relevant laws and regulations1.

Allocating sufficient budget, staff, and technology for information security, and investing in training and awareness programs2.

Promoting a culture of security within the organization, and engaging with stakeholders and partners to foster trust and collaboration2.

The primary reason for an IS auditor to perform a risk assessment is to help identify areas with a relatively high probability of material problems. A risk assessment is a systematic process of evaluating the potential risks that may be involved in an activity or undertaking. It involves identifying the sources of risk, analyzing the likelihood and impact of the risk, and prioritizing the risks based on their significance. A risk assessment helps the IS auditor to focus on the areas that are most vulnerable to errors, fraud, or inefficiencies, and to design appropriate audit procedures to address those risks. A risk assessment also helps the IS auditor to allocate audit resources efficiently and effectively.

A risk assessment does not provide a basis for the formulation of corrective action plans, as this is a responsibility of management, not the IS auditor. A risk assessment does not increase awareness of the types of management actions that may be inappropriate, as this is a matter of professional ethicsand judgment. A risk assessment does not help to identify areas that are most sensitive to fraudulent or inaccurate practices, as this is a result of the risk assessment, not its purpose.

 An IT strategic plan that best leverages IT in achieving organizational goals will include enterprise architecture (EA) impacts. EA is the practice of analyzing, designing, planning, and implementing enterprise analysis to successfully execute on business strategies1. EA helps organizations structure IT projects and policies to align with business goals, to stay agile and resilient in the face of rapid change, and to stay on top of industry trends and disruptions1. EA also describes an organization’s processes, information processes and personnel and other organizational subunits aligned with the organization’s core goals and strategies2. By including EA impacts in the IT strategic plan, an organization can ensure that the IT initiatives are consistent with the business vision, objectives, and tactics, and that they support the desired business outcomes3.

A comparison of future needs against current capabilities, a risk-based ranking of projects, and IT budgets linked to the organization’s budget are all important elements of an IT strategic plan, but they do not necessarily leverage IT in achieving organizational goals. A comparison of future needsagainst current capabilities can help identify gaps and opportunities for improvement, but it does not provide a clear direction or roadmap for how to achieve them. A risk-based ranking of projects can help prioritize the most critical and beneficial projects, but it does not ensure that they are aligned with the business strategy or that they deliver value to the stakeholders. IT budgets linked to the organization’s budget can help allocate resources and monitor costs, but they do not reflect the impact or contribution of IT to the business performance or growth.

The best indicator of the performance of a web application is the average response time. This metric measures how long it takes for the web server to process and deliver a request from the client. It reflects the user’s perception of how fast or slow the web application is, and it affects the user’s satisfaction, engagement, and conversion. A low average response time means that the web application is responsive and efficient, while a high average response time means that the web application is sluggish and unreliable.

HTTP server error rate, server thread count, and server uptime are not as good indicators of the performance of a web application as the average response time. HTTP server error rate measures how often the web server fails to handle a request and returns an error code, such as 404 (Not Found) or 500 (Internal Server Error). This metric indicates the reliability and availability of the web application, but it does not capture how fast or slow the web application is. Server thread count measures how many concurrent requests the web server can handle at a given time. This metric indicates the scalability and capacity of the web application, but it does not capture how long each request takes to process. Server uptime measures how long the web server has been running without interruption. This metric indicates the stability and resilience of the web application, but it does not capture how well the web application performs during that time.

Obtaining management’s consent to the testing scope in writing is the most important step prior to finalizing the scope of testing, as it ensures that the penetration testers have the authorization and approval to perform the testing activities. It also protects them from any legal liabilities or accusations of unauthorized access or damage. The other options are not as important as obtaining management’s consent, and they may vary depending on the specific situation and agreement. For example, some systems may not be excluded from the testing scope, and some tests may not be restricted to the test environment. References: CISA Review Manual (Digital Version) 1, page 381-382.

The best reason to implement a data retention policy is to limit the liability associated with storing and protecting information. A data retention policy is a business’ established protocol for maintaining information, typically defining what data needs to be retained, the format in which it should be kept, how long it should be stored for, whether it should eventually be archived or deleted, who has the authority to dispose of it, and what procedure to follow in the event of a policy violation1. A data retention policy can help an organization to:

Comply with legal and regulatory requirements that mandate the retention and disposal of certain types of data, such as financial records, health records, or personal data

Reduce the risk of data breaches, theft, loss, or corruption by minimizing the amount of data stored and ensuring proper security measures are in place

Save costs and resources by optimizing the use of storage space and reducing the need for backup and recovery operations

Enhance operational efficiency and performance by eliminating unnecessary or outdated data and improving data quality and accessibility

Support business continuity and disaster recovery plans by ensuring critical data is available and recoverable in case of an emergency

Facilitate audit trails and investigations by providing evidence of data authenticity, integrity, and provenance

Therefore, by implementing a data retention policy, an organization can limit its liability associated with storing and protecting information, as well as improve its data governance and management practices.

The best tool for detailed testing of a business application’s data and configuration files is an audit analytics tool. An audit analytics tool is a software that helps auditors to analyze large sets of data and identify anomalies, trends, and patterns that are relevant to the audit objectives. An audit analytics tool can also provide audit evidence and support the auditor’s professional judgment and conclusions.

Some of the benefits of using an audit analytics tool are:

It can improve the efficiency and effectiveness of the audit by reducing the time and effort required to perform manual tests and procedures.

It can enhance the quality and reliability of the audit by increasing the coverage and accuracy of the data analysis and testing.

It can enable the auditor to perform more complex and sophisticated tests and procedures that may not be possible or feasible with traditional methods.

It can help the auditor to discover new insights and risks that may not be apparent or detectable with traditional methods.

Some examples of audit analytics tools are:

IDEA: A data analysis software that allows auditors to import, analyze, and visualize data from various sources and formats. It also offers features such as sampling, stratification, gap analysis, duplicate detection, Benford’s law, and regression analysis.1

ACL: A data analysis software that helps auditors to access, analyze, and report on data from various sources and formats. It also offers features such as sampling, stratification, gap analysis, duplicate detection, Benford’s law, regression analysis, and scripting.2

TeamMate Analytics: A data analysis software that integrates with Microsoft Excel and provides auditors with a range of tools and functions to perform data analysis and testing. It also offers features such as sampling, stratification, gap analysis, duplicate detection, Benford’s law, regression analysis, and scripting.3

The issue seems to stem from a breakdown in the workflow or process for handling assets that are due for destruction12. By examining the workflow, the IS auditor can identify where the process failed, such as why the vendor was not notified about the hard drives12. This could involve reviewing procedures for inventory management, communication with vendors, and tracking of assets due for destruction12. The findings can then be used to improve the workflow and prevent similar issues in the future12.

When an IS auditor discovers a security weakness in the database configuration, the next course of action should be to identify existing mitigating controls. This involves assessing whether any controls are already in place to address the weakness and mitigate the risk. Understanding the current state of controls helps the auditor determine the severity of the issue and whether additional corrective actions are

The most critical factor for the success of an information security program is management’s commitment to information security. Management’s commitment to information security means that the senior management supports, sponsors, funds, monitors and enforces the information security program within the organization. Management’s commitment to information security also demonstrates leadership, sets the tone and culture, and establishes the strategic direction and objectives for information security. User accountability for information security, alignment of information security with IT objectives, and integration of business and information security are also important factors for the success of an information security program, but they are not as critical as management’s commitment to information security, as they depend on or derive from it. References: Info Technology & Systems Resources | COBIT, Risk, Governance … - ISACA, IT Governance and Process Maturity

According to the ISACA CISA documentation, one of the requirements for internal audit quality assurance (QA) and continuous improvement processes is to have an external assessment at least once every five years by a qualified, independent reviewer or review team from outside the organization1. This is to ensure that the internal audit activity conforms to the International Standards for the Professional Practice of Internal Auditing (the Standards) and the Code of Ethics, and to identify opportunities for improvement2. Therefore, the lack of periodic engagement with external assessors would present the greatest concern during a review of internal audit QA and continuous improvement processes.

 Validation controls are used to check the input data from the user before processing it on the server. If the validation controls are moved from the server side to the browser, it means that the user can modify or bypass them using tools such as browser developer tools, JavaScript console, or proxy tools. This would increase the risk of a successful attack by structured query language (SQL) injection, which is a technique that exploits a security vulnerability in an application’s software layer that allows an attacker to execute arbitrary SQL commands on the underlying database. SQL injection can result in data theft, data corruption, or unauthorized access to the system.

Buffer overflow, denial of service (DoS), and phishing are not directly related to the validation controls in a web application. Buffer overflow is a type of attack that exploits a memory management flaw in an application or system that allows an attacker to write data beyond the allocated buffer size and overwrite adjacent memory locations. DoS is a type of attack that prevents legitimate users from accessing a service or resource by overwhelming it with requests or traffic. Phishing is a type of attack that uses fraudulent emails or websites to trick users into revealing sensitive information or installing malware.

The type of risk that would most influence the selection of a sampling methodology is detection risk (option D). This is because:

Detection risk is the risk that the auditor will not detect a material misstatement that exists in an assertion1. Detection risk depends on the effectiveness of the audit procedures and how well they are applied by the auditor1.

The selection of a sampling methodology is part of the design of audit procedures, which aims to reduce detection risk to an acceptable level1. The auditor should consider the following factors when selecting a sampling methodology23:

The objectives of the audit procedure and the related assertions.

The characteristics of the population from which the sample will be drawn, such as its size, homogeneity, and structure.

The sampling technique to be used, such as random, systematic, haphazard, or judgmental.

The sample size and the method of selecting sample items.

The evaluation of the sample results and the projection of errors to the population.

The auditor should also consider the advantages and disadvantages of different sampling methodologies, such as statistical and non-statistical sampling23. Statistical sampling is a sampling technique that uses random selection and probability theory to evaluate sample results. Non-statistical sampling is a sampling technique that does not use random selection or probability theory to evaluate sample results. Some of the advantages and disadvantages are as follows23:

Statistical sampling allows the auditor to measure and control sampling risk, which is the risk that the sample is not representative of the population. Statistical sampling also allows the auditor to quantify the precision and reliability of the sample results. However, statistical sampling requires more technical knowledge and skills, as well as more time and cost, than non-statistical sampling.

Non-statistical sampling relies on the auditor’s professional judgment and experience to select and evaluate sample items. Non-statistical sampling is more flexible and less complex than statistical sampling. However, non-statistical sampling does not provide an objective basis for measuring and controlling sampling risk, nor does it allow the auditor to quantify the precision and reliability of the sample results.

Therefore, the type of risk that would most influence the selection of a sampling methodology is detection risk (option D), as it determines how effective and efficient the audit procedures should be in order to provide sufficient appropriate audit evidence.

The best way to provide assurance that a project is adhering to the project plan is to conduct compliance audits at major system milestones. A compliance audit is a systematic and independent examination of the project’s activities, documents, and deliverables to determine whether they conform to the project plan and its specifications, standards, and requirements1. A major system milestone is a significant point or event in the project’s life cycle that marks the completion of a phase, stage, or deliverable2.

By conducting compliance audits at major system milestones, the auditor can provide assurance that the project is adhering to the project plan by:

Verifying that the project’s scope, schedule, budget, quality, and risks are aligned with the project plan and its objectives1

Identifying any deviations, discrepancies, or non-compliances that may affect the project’s performance or outcome1

Recommending and monitoring corrective and preventive actions to address the identified issues and improve the project’s compliance1

Reporting and communicating the audit findings, conclusions, and recommendations to the relevant stakeholders1

The other options are not as effective as conducting compliance audits at major system milestones for providing assurance that the project is adhering to the project plan. Requiring design reviews at appropriate points in the life cycle is a useful technique for ensuring that the project’s design meets the user and business requirements and follows the design standards and best practices3. However, design reviews are not sufficient for providing assurance that the project is adhering to the project plan, as they do not cover other aspects of the project such as schedule, budget, quality, or risks. Having an IS auditor participate on the steering committee is a possible way for providing assurance that the project is adhering to the project plan, as the auditor can provide independent advice and oversight to the steering committee on quality management issues and remediation efforts4. However, this may not be feasible or appropriate for every project, as it may create a conflict of interest or compromise the auditor’s objectivity and independence. Having an IS auditor participate on the quality assurance (QA) team is another possible way for providing assurance that the project is adhering to the project plan, as the auditor can assist the QA team in implementing procedures to facilitate adoption of quality management best practices5. However, this may also not be feasible or appropriate for every project, as it may create a conflict of interest or compromise the auditor’s objectivity and independence. Therefore, option D is the correct answer.

The best evidence to determine whether transactions have been executed by authorized employees is audit trails. Audit trails are secure records that catalog events or procedures to provide support documentation. They are used to authenticate security and operational actions, mitigate challenges, or provide proof of compliance and operational integrity2. Audit trails can track and trace the following information related to transactions:

Who initiated, approved, modified, or deleted a transaction

When a transaction occurred (date and time)

Where a transaction took place (location or device)

What type of transaction was performed (action or operation)

Why a transaction was executed (purpose or reason)

By analyzing audit trails, an IS auditor can verify whether transactions have been executed by authorized employees or not. Audit trails can also identify any unauthorized, fraudulent, or erroneous transactions that may have occurred. Audit trails can also help to resolve any disputes or discrepancies that may arise from transactions.

Automated version control systems are the best method to maintain an audit trail of changes made to the source code of a program. They automatically track and manage changes to the source code over time, allowing you to see what changes were made, when they were made, and who made them1. This provides a clear and detailed audit trail that can be invaluable for debugging, understanding the evolution of the code, and ensuring accountability23.

Machine shredding is the process of using a shredding machine to physically destroy the media and make the data unrecoverable. This is more effective than software formatting, which only erases the data logically and may leave traces that can be recovered by special tools1. Encrypting and destroying keys may prevent unauthorized access to the data, but it does not erase the data from the media. Wiping and rewriting three times is unnecessary and may reduce the lifespan of the media, especially for solid state drives2. Machine shredding is also recommended by various security standards and guidelines for media disposal345.

The greatest concern with the lack of structure for technology risk governance is C. Key decision-making entities for technology risk have not been identified. Technology risk governance is the process of establishing and maintaining the policies, roles, responsibilities, and accountabilities for managing technology risks within an organization1. Technology risk governance requires a clear organizational structure that defines who has the authority and responsibility to make decisions, set objectives, allocate resources, monitor performance, and ensure compliance for technology risk management2. Without such a structure, an organization may face the following challenges:

Lack of alignment and integration between technology and business strategies, leading to suboptimal outcomes and missed opportunities.

Lack of clarity and consistency in technology risk identification, assessment, mitigation, and reporting, leading to gaps and overlaps in risk coverage and exposure.

Lack of communication and collaboration among different stakeholders involved in technology risk management, leading to conflicts and inefficiencies.

Lack of oversight and accountability for technology risk management activities and results, leading to poor quality and reliability.

Post-implementation testing is the process of verifying and validating the functionality, performance, and security of a system after it has been deployed to the production environment1. Post-implementation testing is important for ensuring that the system meets the user requirements and expectations, as well as the operational and business objectives. Post-implementation testing also helps to identify and resolve any defects, errors, or issues that may have occurred during the deployment process or that may have been missed during the previous testing stages2.

Therefore, the observation that post-implementation testing is not conducted for all system releases should be of greatest concern to an IS auditor performing an audit of change and release management controls for a new complex system developed by a small in-house IT team. This observation indicates that the system may have quality, reliability, or security problems that could affect the user satisfaction, system performance, or data integrity. This observation also suggests that the change and release management controls are not adequate or effective, as they do not ensure that all system releases are properly tested and validated before and after deployment.

Option A is not correct because access to change testing strategy and results is not restricted to staff outside the IT team is not a major concern for an IS auditor. While it is good practice to limit access to sensitive or confidential information, such as test data or test cases, to authorized personnel only, access to change testing strategy and results may not pose a significant risk to the system or the organization. Moreover, access to change testing strategy and results may be beneficial for some stakeholders outside the IT team, such as business users, project managers, or auditors, who may need to review or evaluate the testing process or outcomes.

Option B is not correct because some user acceptance testing (UAT) was completed by members of the IT team is not a major concern for an IS auditor. User acceptance testing is the process of verifying and validating that the system meets the user requirements and expectations by involving actual or representative users in the testing process3. While it is preferable to have independent and unbiased users perform UAT, it may not be feasible or practical for some organizations, especially those with small or limited resources. Therefore, some UAT may be completed by members of the IT team, as long as they have sufficient knowledge and experience of the user needs and expectations, and as long as they follow the UAT plan and criteria.

Option C is not correct because IT administrators have access to the production and development environment is not a major concern for an IS auditor. IT administrators are responsible for managing and maintaining the IT infrastructure, including the production and development environments4. Therefore, it is reasonable and necessary for them to have access to both environments, as long as they follow the appropriate policies and procedures for accessing, using, and securing them. Moreover, IT administrators may need to perform tasks such as backup, restore, patching, or troubleshooting in both environments.

The most effective control to maintain segregation of duties in a DevOps environment is A. Enforce approval prior to deployment by a member of the team who has not taken part in the development. Segregation of duties (SoD) is a principle that requires multiple actors to complete a task to reduce the risk of fraud, error, or abuse1. In a DevOps environment, where developers and operators work together to deliver software faster and more reliably, SoD may seem to be incompatible or impractical. However, SoD can still be achieved by implementing controls that ensure that no single person can develop, test, and deploy code without oversight or review2.

Enforcing approval prior to deployment by a member of the team who has not taken part in the development is an effective control that ensures that code changes are verified and validated by a peer before they are released to production. This control can help prevent or detect any unauthorized or malicious modifications, errors, or vulnerabilities in the code, and ensure that the code meets the quality and security standards3. This control can also promote collaboration and feedback among the team members, and improve the transparency and accountability of the software delivery process3.

Compared to developing a system in-house, acquiring a software package means that the need for testing by end users is unchanged. This is because end users are still the ultimate customers and beneficiaries of the system, and they need to ensure that the software package meets their requirements, expectations, and satisfaction. End user testing, also known as user acceptance testing (UAT) or beta testing, is the final stage of testing performed by the user or client to determine whether the software can be accepted or not1. Enduser testing is important for both in-house developed and acquired software packages, as it helps to verify the functionality, usability, performance, and reliability of the system2. End user testing also helps to identify and resolve any defects, errors, or issues that may not have been detected by the developers or vendors3.

Therefore, option B is the correct answer.

Option A is not correct because end user testing is not eliminated by acquiring a software package. Even though the software package may have been tested by the vendor or supplier, it may still have bugs, compatibility issues, or configuration problems that need to be fixed before deployment4. Option C is not correct because end user testing is not increased by acquiring a software package. The scope and extent of end user testing depend on various factors, such as the complexity, criticality, and customization of the system, and not on whether it is developed in-house or acquired. Option D is not correct because end user testing is not reduced by acquiring a software package. The software package may still require modifications or integrations to suit the specific needs and environment of the organization, and these changes need to be tested by the end users.

The most significant impact to an organization that does not use an IT governance framework is inadequate alignment of IT plans and business objectives. IT governance is a framework for the governance and management of enterprise information and technology (I&T) that supports enterprise goal achievement1. IT governance helps to ensure that IT investments and activities are aligned with the business strategy, vision, and values of the organization. IT governance also helps to optimize the value of IT, manage IT-related risks, and measure and monitor IT performance1.

Without an IT governance framework, an organization may face challenges such as:

Lack of clarity and direction for IT decision making

Inconsistent or conflicting IT priorities and demands

Inefficient or ineffective use of IT resources and capabilities

Poor quality or delivery of IT services and products

Increased exposure to IT-related threats and vulnerabilities

Reduced customer satisfaction and trust in IT

Missed opportunities for innovation and competitive advantage

Therefore, an organization that does not use an IT governance framework may fail to achieve its business objectives and may lose its competitive edge in the market.

The IS auditor’s next course of action should be to report this control process weakness to senior management, as it may indicate a lack of oversight and accountability for the reporting system. Read-only users may have access to sensitive or confidential information that should be restricted or monitored. Periodic reviews of read-only users are a good practice to ensure that the access rights are still valid and appropriate for the users’ roles and responsibilities. Reporting this weakness to senior management will also allow them to take corrective actions or implement compensating controls if needed.

Option A is incorrect because reviewing the list of end users and evaluating for authorization is not the IS auditor’s responsibility, but rather the system owner’s or administrator’s. The IS auditor should only verify that such reviews are performed and documented by the responsible parties.

Option C is incorrect because verifying management’s approval for this exemption is not sufficient to address the control process weakness. Even if there is a valid reason for not performing periodic reviews of read-only users, the IS auditor should still report this as a potential risk and recommend mitigating controls.

Option D is incorrect because obtaining a verbal confirmation from IT for this exemption is not adequate evidence or documentation. The IS auditor should obtain written approval from management and verify that it is aligned with the organization’s policies and standards.

The auditor’s best recommendation is D. Introduce problem management into incident response. Problem management is a practice that aims to identify, analyze, and resolve the root causes of recurring incidents, and prevent or reduce their impact in the future1. Problem management can help improve the resolution times for recurring incidents by eliminating or mitigating the underlying problems that cause them, and by providing permanent solutions that can be reused or automated2. Problem management can also help improve the quality and efficiency of incident response by reducing the workload and complexity of dealing with repetitive issues2.

The primary reason to perform internal QA for an internal audit function is to ensure that the internal audit activity adheres to the Definition of Internal Auditing and the International Standards for the Professional Practiceof Internal Auditing (Standards) issued by the Institute of Internal Auditors (IIA), as well as the internal audit methodology and policies of the organization. A QA program enables an evaluation of the internal audit activity’s performance, efficiency, effectiveness, and value, and identifies opportunities for improvement. A QA program also helps to enhance the credibility and reputation of the internal audit function among the stakeholders.

Comprehensive and Detailed Step-by-Step Explanation:

For online payment security, bothconfidentiality(protection of data) andnonrepudiation(ensuring the sender cannot deny a transaction) are essential.

Option A (Incorrect):DES is outdatedandinsecurefor modern encryption needs. It has been replaced by stronger algorithms.

Option B (Incorrect):AES provides strong encryption(confidentiality) but does not handlenonrepudiationon its own.

Option C (Correct):PKI (Public Key Infrastructure)is the best solution because it providesencryption for confidentialityanddigital signatures for nonrepudiation, ensuring bothsecuretransactions andauthenticationof parties involved.

Option D (Incorrect):AVPN secures network traffic, but it does not address nonrepudiation, which is critical in online payments.

Benford's Law analyzes numerical data to detect anomalies based on the frequency distribution of leading digits. For it to be effective, the dataset must follow specific criteria, including consistency in measurement units. If transactions are in different currencies, the leading digits can vary due to currency conversion rates, invalidating the analysis.

Double Integer Format (Option A):Benford’s Law applies to any set of numerical data, not specifically double integers.

Random Selection of Transactions (Option B):The data set must represent the entire population, not a random selection.

Limiting Analysis to Standard Deviations (Option C):This is irrelevant to the application of Benford's Law.

Deep packet inspection (DPI) is a core capability of data loss prevention (DLP) tools that allows the analysis of the content of data packets in transit. This helps detect the unauthorized movement of sensitive data by examining packet-level details.

Network Traffic Logs (Option A):These provide historical data but do not actively detect data in transit.

Data Inventory (Option C):Useful for identifying where sensitive data resides but not for monitoring its movement.

Proprietary Encryption (Option D):Protects data but does not detect unauthorized transmission.

 Periodic review of access profiles by management is an additional control that is required when using swipe cards to limit employee access to restricted areas. Swipe cards are a type of physical access control that use magnetic stripes or radio frequency identification (RFID) to store and transmit information about the cardholder’s identity and access rights. Swipe cards can help to prevent unauthorized entry, protect sensitive assets and data, and monitor access activity. However, swipe cards alone are not enough to ensure effective access control. They need to be complemented by other controls, such as:

Periodic review of access profiles by management: This is a type of logical access control that involves verifying that the access rights assigned to each cardholder are appropriate, necessary, and consistent with the organization’s policies and procedures. Periodic review of access profiles can help to detect and correct any errors, inconsistencies, or violations in the access control system, such as outdated, excessive, or redundant access rights, segregation of duties conflicts, or unauthorized changes. Periodic review of access profiles can also help to ensure compliance with internal and external audit requirements and regulations.

Implementation of additional PIN pads: This is a type of multi-factor authentication (MFA) that requires the cardholder to enter a personal identification number (PIN) in addition to swiping their card. MFA can enhance the security of the access control system by adding another layer of verificationand reducing the risk of lost, stolen, or cloned cards being used by unauthorized persons.

Installation of closed-circuit television (CCTV): This is a type of surveillance system that uses cameras and monitors to record and display the images of the people and activities in the restricted areas. CCTV can deter potential intruders, provide evidence of any security incidents or breaches, and enable real-time monitoring and response by security personnel.

The other options are not as effective or relevant as periodic review of access profiles by management for an additional control when using swipe cards. Physical sign-in of all employees for access to restricted areas is a redundant and inefficient control that can be easily bypassed or manipulated. It also does not provide any assurance or verification of the identity or access rights of the cardholders. Audit hooks are software routines embedded in an application that can trigger an alert or a report when certain conditions are met. Audit hooks can help to detect anomalies or exceptions in access control lists, but they do not provide a comprehensive or integrated view of them.

A continuous integration/continuous development (CI/CD) process helps to reduce software failure risk by enabling smaller incremental changes to the software code, rather than large and infrequent updates12. Smaller incremental changes allow developers to detect and fix errors, bugs, or vulnerabilities more quickly and easily, and to ensure that the software is always in a working state34. Smaller incremental changes also reduce the complexity and uncertainty of the software development process, and improve the quality and reliability of the software product5.

A strongQA functionrequires anindependentreview of changes toavoid biasandensure objectivity.

Option A (Correct):Ifdevelopers review their own changes, there is ahigh risk of biasand overlooking issues, making this the greatest concern. This violatesseparation of dutiesandbest practices for quality assurance.

Option B (Incorrect):Peer reviews within the same teamreduce risksincefresh eyesreview the changes, though it is not as strong as an external review.

Option C (Incorrect):Havingdevelopers from a separate teamreview the code providesbetter objectivityand reduces risks associated withself-review.

Option D (Incorrect):Whilenon-developers may lack technical expertise, their review ensuresindependence, making it a stronger control than self-review.

Operational log management primarily enhances security by enabling real-time monitoring and detection of anomalies within network data. Logs provide valuable information for identifying threats, investigating incidents, and ensuring compliance with security policies.

Predictive Analysis for User Experience (Option A):While logs may support analytics, this is not the primary benefit.

Performance Issue Identification (Option C):Logs can help identify performance issues, but the focus of operational log management is security.

Data Aggregation Using Unified Storage (Option D):This supports management but is secondary to the security benefits.

Unauthorized data modifications during conversion (D) are the most critical concern because they compromise data integrity, leading to inaccurate or corrupted information in the new system. Data migration should be performed with strict controls, including validation, reconciliation, and audit trails.

Other options:

Lack of online backups (A) is a risk but not as severe as compromised data integrity. Offline backups may still exist.

Undocumented change management (B) is a process deficiency but does not directly affect data accuracy.

Manual data conversion (C) increases risk but does not automatically indicate unauthorized changes.

The stakeholder’s role in automating data extraction and validation is to indicate which data elements are necessary to make informed decisions. The stakeholder is the person who has a vested interest in the outcome of the data analytics process and can provide the business context and requirements for the analysis. The stakeholder can help the data analyst to identify the relevant data sources, the key performance indicators (KPIs), and the expected results of the analysis.

The IS auditor should be most concerned if completeness testing has not been performed on the log data, as this could indicate that some logs are missing, corrupted, or tampered with, and that the log aggregation system is not reliable or accurate12. Completeness testing is a process of verifying that all the logs generated by the source systems are successfully collected, transferred, and stored by the log aggregation system, and that there are no gaps or inconsistencies in the log data34. Completeness testing is essential for ensuring the integrity and validity of the log data, and for supporting the risk management practices of the organization.

Higher OS License Fees (Incorrect – A)

License feesmay increase, butdowntime risk is a greater concern.

Simplified Asset Management (Incorrect – C)

True, butdoes not outweigh the availability risk.

Fewer Vulnerability Scans (Incorrect – D)

Reducing the number of serversdoes not reduce security risks.

Here's the breakdown, considering

the need for DLP visibility in the cloud:

Verified Answer

C. Employ a cloud access security broker (CASB).

Very Short Explanation

CASBs are specifically designed to enhance visibility and control over cloud-based data. They can monitor data flows, enforce security policies, and often have DLP capabilities built-in, making them the ideal solution in this scenario.

ISACA Resources (Glossary): Definitions of Cloud Access Security Broker (CASB) highlight their role in cloud security and governance.

Industry Research (Gartner, etc.): Research on CASB tools emphasizes their ability to address visibility and control challenges for cloud data.

The success rate of social engineering attacks directly measures the behavioral changes resulting from an information security awareness program. Employees who are aware and informed are better equipped to identify and thwart such attacks.

Reduction in Reported Incidents (Option A):This may indicate underreporting rather than program effectiveness.

Reduction in Cost of Maintaining the Program (Option C):This reflects cost efficiency, not program effectiveness.

Reduction in Number of Attacks (Option D):The number of attacks is beyond the control of awareness programs and does not reflect their impact.

Shadow IT often arises when approved software does not meet user requirements (Option D), leading employees to seek alternative solutions.

ISACA CISA Reference: IT governance frameworks stress the need for user-centric IT policies to mitigate shadow IT risks.

Risk Implication: Shadow IT introduces security vulnerabilities, compliance risks, and potential data breaches.

To reduce false positive alerts, it is essential to carefully configure a limited set of rules tailored to the organization's specific data loss prevention needs. This ensures that the DLP tool accurately identifies true positives and reduces the occurrence of false alarms.

The primary purpose of a Business Impact Analysis (BIA) is to prioritize the restoration of systems and applications (D) based on their criticality to business operations. A BIA assesses the impact of disruptions, identifies critical processes, and determines recovery time objectives (RTOs) and recovery point objectives (RPOs).

Other options:

Identifying legal obligations (A) is an aspect of compliance but not the primary benefit of a BIA.

Providing updates on disaster risk levels (B) falls under risk management rather than BIA objectives.

Delineating employee responsibilities (C) is part of business continuity planning (BCP), not the BIA’s main goal.

Comprehensive and Detailed Step-by-Step Explanation:

IfIT is not involvedinstrategic planning,IT strategy may diverge from business needs, leading tomisalignment and inefficiencies.

Option A (Incorrect):Business strategy alignmentis important, but the greater risk is thatIT investments do not support business goals.

Option B (Incorrect):Lack of emerging technology awareness is a risk, butIT-business misalignment has broader consequences.

Option C (Correct):Thegreatest riskis when IT strategyfails to align with business objectives, leading towasted investments, inefficiencies, and competitive disadvantages.

Option D (Incorrect):IT goals being overlooked is a concern, butmisalignment of IT and business strategies is a more critical risk.

Comprehensive and Detailed Step-by-Step Explanation:Transposition and transcription errors occur when characters or numbers are accidentally swapped or misentered during data entry.

Option A (Incorrect):Duplicate checks ensure that the same record is not entered twice but do not specifically detect transposition or transcription errors.

Option B (Incorrect):Completeness checks ensure that all required data is entered but do not validate data accuracy.

Option C (Incorrect):Sequence checks verify that records follow a logical sequence but do not catch errors within individual data entries.

Option D (Correct):Acheck digitis an additional number generated through an algorithm (e.g., Luhn algorithm for credit cards) that helps detect errors such as transpositions (e.g., swapping digits 45 → 54) and transcriptions (e.g., mistyping 8 as 3).

Enterprise Architecture (EA) documentation primarily includes strategic and operational blueprints outlining the evolution of IT infrastructure to align with business goals. Roadmaps showing the evolution from current state to future state (C) are essential for understanding how the organization’s IT environment will change over time to support business strategy.

Other options:

Contact information for key resources (A) is more of an operational or administrative document rather than an EA component.

Detailed encryption standards (B) would typically be found in security policies or system-specific documentation rather than in EA documentation.

Protocols used to communicate between systems (D) are typically documented within network or system architecture diagrams rather than high-level EA documentation.

Comprehensive and Detailed Step-by-Step Explanation:

A lack ofMobile Device Management (MDM) enrollmentis the biggest concern, asunmanaged devicespose a serious security risk.

Not All Devices Enrolled in MDM (Correct Answer – C)

Unenrolled devices can bypass security policies.

Example:A stolen, unenrolled device may lack encryption, exposing corporate data.

Biometric Authentication Required (Incorrect – A)

Biometrics are anenhanced security measure, not a concern.

VPN Not Required for Internal Network (Incorrect – B)

VPNs are typically used for external access, not always needed internally.

Remote Wipe Requires Internet (Incorrect – D)

A limitation but stillless riskythan allowing unsecured devices.

Ransomwareis a type of malicious software that encrypts the victim’s data and demands a ransom for its decryption1. Ransomware attacks can cause significant damage to an organization’s operations, reputation, andfinances1. Therefore, it is important to mitigate the impact of ransomware attacks by implementing effective prevention and recovery strategies.

One of the best ways to mitigate the impact of ransomware attacks is to back up data frequently12345. Data backups are copies of the organization’s data that are stored in a separate location or medium, such as an external harddrive, cloud storage, or tape2. Data backupscan help the organization restore its data in case of a ransomware attack, without paying the ransom or losing valuable information2. Data backups shouldbe performed regularly, preferably daily or weekly, depending on the criticality and volume of the data2. Data backups should also be tested periodically to ensure their integrity and usability2.

The other options are not as effective as backing up data frequently in mitigating the impact of ransomware attacks. Invoking the disaster recovery plan (DRP) is a reactive measure that can help the organization resume its operations after a ransomware attack, but it does not prevent or reduce the damage caused by the attack3. Paying the ransom is not a recommended option, as it does not guarantee the decryption of the data or the deletion of the stolen data by the attackers. Paying the ransom also encourages further attacks and funds criminal activities14. Requiring password changes for administrative accounts is a good security practice, but it is not sufficient to prevent or recover from ransomware attacks. Ransomware attacks can exploit other vulnerabilities, such as phishing emails, outdated software, or weak network security15.

Deferring remediation testing until the next audit is justified only when there are significant changes in the audit environment that affect the relevance or validity of the audit observations and recommendations. For example, if there are changes in the business processes, systems, regulations, or risks that require a new audit scope or approach. The other options are not valid justifications for deferring remediation testing, as they do not address the timeliness or quality of the audit follow-up process. The auditor who conducted the audit and agreed with the timeline has left the organization does not affect the responsibility of the audit function to ensure that remediation testing is performed as planned. Management’s planned actions are sufficient given the relative importance of the observations does not guarantee that management will actually implement those actions or that they will be effective in addressing the audit issues. Auditee management has accepted all observations reported by the auditor does not eliminate the need for verification of remediation actions by an independent party. References: CISA Review Manual (Digital Version), Chapter 2, Section 2.4

The first course of action that the auditor should recommend after finding that several employees are spending an excessive amount of time using social media sites for personal reasons is to implement policies addressing acceptable usage of social media during working hours. Policies can help define the scope, purpose, rules, and expectations of using social media in the workplace, both for personal and professional reasons. Policies can also specify the consequences of violating the policies, such as disciplinary actions or termination. Policies can help deter employees from misusing social media at work, which could affect their productivity, performance, or security. Policies can also help protect the organization from legal liabilities or reputational damages that could arise from inappropriate or unlawful employee behavior on social media. 

Reviewing the performance against service level agreements (SLAs) would best determine whether the service provider continues to meet the organization’s objectives, as SLAs define the expected level of service, quality, availability, and responsibilities of both parties. Assessment of the personnel training processes of the provider, adequacy of the service provider’s insurance, and periodic audits of controls by an independent auditor are important aspects of outsourcing, but they do not directly measure the performance of the service provider against the organization’s objectives. References: CISA Review Manual (Digital Version), Chapter 3, Section 3.5.2

 A proper audit trail of changes to server start-up procedures would include evidence of operator overrides, which are actions taken by the system operator to bypass or modify the normal execution of the server start-up process. Operator overrides may indicate unauthorized or improper changes that could affect the security, availability, or performance of the server. Therefore, an audit trail should capture and document any operator overrides that occur during the server start-up process.

Evidence of subsystem structure, program execution, and security control options are not directly related to changes to server start-up procedures. Subsystem structure refers to the components and relationships of a subsystem within a larger system. Program execution refers to the process of running a software program on a computer. Security control options refer to the settings and parameters that define the security level and access rights for a system or application. These are all important aspects of auditing a server, but they do not provide evidence of changes to server start-up procedures.

 The metric that best indicates the effectiveness of awareness training is the number of users reporting receipt of the email to the information security team. This shows that the users are able to recognize and report a phishing email, which is a common social engineering technique used by attackers to trick users into revealing sensitive information or installing malicious software. The other metrics do not demonstrate a high level of security awareness, as they either ignore, follow, or forward the phishing email, which could expose the organization to potential risks. References: CISA Review Manual, 27th Edition, page 326

 An employee is induced to reveal confidential IP addresses and passwords by answering questions over the phone. This is a social engineering attack method that exploits the trust or curiosity of the employee to obtain sensitive information that can be used to access or compromise the network. According to the web search results, social engineering is a technique that uses psychological manipulationto trick users into making security mistakes or giving away sensitive information1. Phishing, whaling, baiting, and pretexting are some of the common forms of social engineering attacks2. Social engineering attacks are often more effective and profitable than purely technical attacks, as they rely on human error rather than system vulnerabilities

Understanding the business process is the most important factor for an effective control self-assessment (CSA) program. A CSA program is a technique that allows managers and work teams directly involved in business units, functions or processes to participate in assessing the organization’s risk management and control processes1. A CSA program can help identify risks and potential exposures to achieving strategic business objectives, evaluate the adequacy and effectiveness ofcontrols, and implement remediation plans to address any gaps or weaknesses2. To conduct a successful CSA, it is essential to have a clear and comprehensive understanding of the business process under review, including its objectives, inputs, outputs, activities, resources, dependencies, stakeholders, performance indicators, etc. This will help to identify the relevant risks and controls associated with the process, as well as to evaluate their impact and likelihood. Determining the scope of the assessment, performing detailed test procedures, and evaluating changes to the risk environment are also important factors for an effective CSA program, but not as important as understanding the business process. These factors are more related to the execution and monitoring phases of the CSA program, while understanding the business process is related to the planning and preparation phase. Without a solid understanding of the business process, the scope, testing, and evaluation of the CSA may not be accurate or complete. References: ISACA CISA Review Manual 27th Edition, page 310

Business processes should be the primary focus of an IS auditor when developing a risk-based IS audit program, because they represent the core activities and functions of the organization that support its objectives and goals. Business processes also involve the use of IT resources and systems that may pose risks to the organization’s performance and compliance. A risk-based IS audit program should identify and assess the risks associated with the business processes and determine the appropriate audit scope and procedures to provide assurance on their effectiveness and efficiency. Portfolio management, business plans, and IT strategic plans are also relevant factors for developing a risk-based IS audit program, but they are not as important as business processes. References: CISA Review Manual (Digital Version), Chapter 2, Section 2.2.1

 Configuring each authentication server as belonging to a cluster of authentication servers is the best way to minimize performance degradation of servers used to authenticate users of an e-commerce website. A cluster is a group of servers that work together to provide high availability, load balancing, and fault tolerance. If one server fails or becomes overloaded, another server in the cluster can take over its workload without disrupting the service. A single server as a primary authentication server and a second server as a secondary authentication server is not as effective as a cluster, because the secondary server is only used when the primary server fails, which means it is idle most of the time and does not improve performance. Configuring each authentication server and ensuring that each disk of its RAID is attached to the primary controller does not address the issue of performance degradation, but rather the issue of data redundancy and reliability. RAID (redundant array of independent disks) is a technology that combines multiple disks into a logical unit that can tolerate disk failures and improve data access speed. Configuring each authentication server and ensuring that the disks of each server form part of a duplex does not address the issue of performance degradation, but rather the issue of data backup and recovery. A duplex is a pair of disks that store identical copies of data, so that if one disk fails, the other disk can be used to restore the data. References: ISACA CISA Review Manual 27th Edition, page 310

The IS auditor’s most important course of action after finding that several similar incidents were logged during the audit period is to determine if a root cause analysis was conducted. A root cause analysis is a systematic process that identifies the underlying causes of system failures or incidents. A root cause analysis can help to prevent recurrence of similar incidents, improve system performance and reliability, and enhance incident management processes. The IS auditor should evaluate whether a root cause analysis was performed for each incident, whether it was timely and thorough, and whether it resulted in effective corrective actions.

The best source of information for assessing the effectiveness of IT process monitoring is performance data. Performance data is a type of information that measures and reports on the results or outcomes of IT processes, such as availability, reliability, throughput, response time, or error rate. Performance data can help assess the effectiveness of IT process monitoring by providing quantitative and qualitative indicators of whether IT processes are meeting their objectives, standards, or expectations. The other options are not as good as performance data in assessing the effectiveness of IT process monitoring, as they do not provide direct or objective evidence of IT process results or outcomes. Real-time audit software is a type of tool that can help automate and facilitate audit activities, such as data collection, analysis, or reporting, but it does not provide information on IT process performance. Quality assurance (QA) reviews are a type of activity that can help evaluate and improve the quality of IT processes, products, or services, but they do not provide information on IT process performance. Participative management techniques are a type of method that can help involve and motivate IT staff in decision-making and problem-solving processes, but they do not provide information on IT process performance. References: CISA Review Manual (Digital Version), Chapter 3, Section 3.3

Referential integrity is a property of data that ensures that all references between tables are valid and consistent. Disabling referential integrity controls can result in orphaned records, data anomalies, and inaccurate queries. The most effective way to compensate for the lack of referential integrity is to perform periodic table link checks, which verify that all foreign keys match existing primary keys in the related tables. More frequent data backups, concurrent access controls, and performance monitoring tools do not address the issue of data consistency and accuracy. References: ISACACISA Review Manual 27th Edition, page 291

The best recommendation for a small IT web development company where developers must have write access to production is to remove production access from the developers. Production access is the ability to modify or update the live systems or applications that are used by customers or end users. Production access should be restricted to authorized and qualified personnel only, as any changes or errors in production can affect the functionality, performance, or security of the systems or applications. Developers should not have write access to production, as they may introduce bugs,vulnerabilities, or inconsistencies in the code that can compromise the quality or reliability of the systems or applications. The other options are not as effective as removing production access from the developers, as they do not address the root cause of the problem or provide the same benefits. Hiring another person to perform migration to production is a costly solution that can help segregate the roles and responsibilities of developers and migrators, but it does not remove production access from the developers. Implementing continuous monitoring controls is a good practice that can help detect and correct any issues or anomalies in production, but it does not remove production access from the developers. Performing a user access review for the development team is a detective control that can help verify and validate the access rights and privileges of developers, but it does not remove production access from the developers. References: CISA Review Manual (Digital Version), Chapter 3, Section 3.2

Parallel processing is a system implementation approach that involves running the new system and the old system simultaneously for a period of time until the new system is verified and accepted. The primary advantage of parallel processing is that it provides assurance that the new system meets performance requirements and produces the same or better results as the old system. Parallel processing also minimizes the risk of system failure and data loss, as the old system can be used as a backup or fallback option in case of any problems with the new system.

Controls to minimize risk and maximize value for the IT portfolio should be the most important consideration when conducting a review of IT portfolio management, because they ensure that the IT portfolio aligns with the business strategy, objectives, and priorities, and that the IT investments deliver optimal benefits and outcomes. Assignment of responsibility for each project to an IT team member, adherence to best practice and industry approved methodologies, and frequency of meetings where the business discusses the IT portfolio are also relevant aspects of IT portfolio management, but they are not asimportant as controls to minimize risk and maximize value. References: CISA Review Manual (Digital Version),Chapter 1, Section 1.2.3

 The decision to accept an IT control risk related to data quality should be the responsibility of the business owner. The business owner is the person who has the authority and accountability for the business process that relies on the data quality. The business owner should understand the impact of data quality issues on the business objectives, performance, and compliance. The business owner should also be involved in defining the data quality requirements, assessing the data quality risks, and implementing the data quality controls or mitigation strategies.

 The most important benefit of involving IS audit when implementing governance of enterprise IT is providing independent and objective feedback to facilitate improvement of IT processes.Governance of enterprise IT is the process of ensuring that IT supports the organization’s strategy, goals, and objectives in an effective, efficient, ethical, and compliant manner. IS audit can provide value to governance of enterprise IT by assessing the alignment of IT with business needs, evaluating the performance and value delivery of IT, identifying risks and issues related to IT, recommending corrective actions and best practices, and monitoring the implementation and effectiveness of IT governance activities. IS audit can also provide assurance that IT governance processes are designed and operating in accordance with relevant standards, frameworks, laws, regulations, and contractual obligations. Identifying relevant roles for an enterprise IT governance framework is a benefit of involving IS audit when implementing governance of enterprise IT, but not the most important one. IS audit can help define and clarify the roles and responsibilities of various stakeholders involved in IT governance, such as board members, senior management, business units, IT function, external parties, etc. IS audit can also help ensure that these roles are aligned with the organization’s strategy, goals, and objectives, and that they have adequate authority, accountability, communication, and reporting mechanisms. However, this benefit is more related to the design phase of IT governance implementation than to the ongoing monitoring and improvement phase. Making decisions regarding risk response and monitoring of residual risk is a benefit of involving IS audit when implementing governance of enterprise IT, but not the most important one. IS audit can help identify and assess the risks associated with IT activities and processes, such as strategic risks, operational risks, compliance risks, security risks, etc. IS audit can also help evaluate the effectiveness of risk management practices and controls implemented by management to mitigate or reduce these risks. However, this benefit is more related to the assurance function of IS audit than to its advisory function. Verifying that legal, regulatory, and contractual requirements are being met is a benefit of involving IS audit when implementing governance of enterprise IT, but not the most important one. IS audit can help verify that IT activities and processes comply with applicable laws, regulations, and contractual obligations, such as data protection laws, privacy laws, cybersecurity laws, industry standards, service level agreements, etc. IS audit can also help identify and report any instances of noncompliance or violations that could result in legal or reputational consequences for the organization. However, this benefit is more related to the assurance function of IS audit than to its advisory function. References: ISACA CISA Review Manual 27th Edition, page 283

 The first thing that an IS auditor should review when finding that transaction processing times in an order processing system have significantly increased after a major release is stress testing results. Stress testing is a type of testing that evaluates how a system performs under extreme or abnormal conditions, such as high volume, load, or concurrency of transactions. Stress testing results can help explain why transaction processing times in an order processing system have significantly increased after a major release by revealing any bottlenecks, limitations, or errors in the system’s capacity, performance, or functionality under stress. The other options are not as relevant as stress testing results in explaining why transaction processing times in an order processing system have significantly increased after a major release, as they do not directly measure how the systemperforms under extreme or abnormal conditions. Capacity management plan is a document that defines and implements the processes and activities for ensuring that the system has adequate resources and capabilities to meet current and future demands. Training plans are documents that define and implement the processes and activities for ensuring that the system users have adequate skills and knowledge to use the system effectively and efficiently. Database conversion results are outcomes or outputs of transforming data from one format or structure to another to suit the system’s requirements or specifications. References: CISA Review Manual (DigitalVersion), Chapter 3, Section 3.3

Data loss can occur due to various reasons, such as accidental deletion, hardware failure, malware infection, theft, or unauthorized access. Data classification procedures can help to identify and protect sensitive data, but they are not sufficient to prevent data loss. The most effective way to protect against data loss is to conduct periodic security awareness training for employees, which can educate them on the importance of data security, the best practices for data handling and storage, and the common threats and risks to data. 

The best document for an IS auditor to use in detecting a weakness in segregation of duties is a process flowchart. A process flowchart is a diagram that illustrates the sequence of steps, activities, tasks, or decisions involved in a business process. A process flowchart can help detect a weakness in segregation of duties by showing who performs what actions or roles in a process, and whether there is any overlap or conflict of interest among them. The other options are not as useful as a process flowchart in detecting a weakness in segregation of duties, as they do not show who performs what actions or roles in a process. A system flowchart is a diagram that illustrates the components, functions, interactions, or logic of an information system. A data flow diagram is a diagram that illustrates how data flows from sources to destinations through processes, stores, or external entities. An entity-relationship diagram is a diagram that illustrates how entities (such as tables) are related to each other through attributes (such as keys) in a database. References: CISA ReviewManual (Digital Version), Chapter 3, Section 3.2

 The IS auditor’s best course of action in this situation is to determine whether the alternative controls sufficiently mitigate the risk. Alternative controls are different from those originally discussed and agreed with the audit function, but they may still achieve the same objective of addressing the audit issue or reducing the risk to an acceptable level. The IS auditor should evaluate whether the alternative controls are appropriate, effective, and sustainable before closing the audit finding or escalating it to senior management. The other options are not appropriate for resolving this situation, as they do not consider whether the alternative controls are adequate or reasonable. Re-prioritizing the original issue as high risk and escalating to senior management is a drastic step that may undermine the relationship between the auditor and management, and it should be done only after exhausting other means of resolving the issue. Scheduling a follow-up audit in the next audit cycle is unnecessary, as follow-up activities should be performed as soon as possible after management has implemented corrective actions. Postponing follow-up activities and escalating the alternative controls to senior audit management is premature, as follow-up activities should be completed before reporting any findings or recommendations to senior audit management. References: CISA Review Manual (Digital Version), Chapter 2, Section 2.4

The expected costs for recovering the business would be used when performing a business impact analysis (BIA). A BIA is a process of identifying and evaluating the potential effects ofdisruptions to critical business functions or processes. A BIA helps to determine the recovery priorities, strategies, and resources needed to resume normal operations after a disruption. One of the key outputs of a BIA is an estimate of the financial losses or costs associated with different types of disruptions, such as lost revenue, increased expenses, contractual penalties, or regulatory fines.

 The first step that an IS auditor should take when finding that a business impact analysis (BIA) has not been performed is to evaluate the impact on current disaster recovery capability. A BIA is a process that identifies and analyzes the potential effects of disruptions to critical business functions and processes. A BIA helps determine the recovery priorities, objectives, and strategies for the organization. Without a BIA, the disaster recovery plan may not be aligned with the business needs and expectations, and may not provide adequate protection and recovery for the most critical assets and activities. Therefore, an IS auditor should assess how the lack of a BIA affects the current disaster recovery capability and identify any gaps or risks that need to be addressed.

Performing a BIA, issuing an intermediate report to management, and conducting additional compliance testing are not the first steps that an IS auditor should take when finding that a BIA has not been performed. These steps may be done later in the audit process, after evaluating the impact on current disaster recovery capability. Performing a BIA is not the responsibility of the IS auditor, but of the business owners and managers. Issuing an intermediate report to management may be premature without sufficient evidence and analysis. Conducting additional compliance testing may not be relevant ornecessary without a clear understanding of the disaster recovery requirements and objectives.

 Secure code reviews as part of a continuous deployment program are preventive controls. Preventive controls are controls that aim to prevent or avoid undesirable events or outcomes from occurring, such as errors, defects, or incidents. Secure code reviews are activities that examine and evaluate the source code of a software or application to identify and eliminate any vulnerabilities, flaws, or weaknesses that may compromise its security, functionality, or performance. Secure code reviews as part of a continuous deployment program can help prevent or avoid security issues or incidents from occurring by ensuring that the code is secure and compliant before it is deployed to production. The other options are not correct types of controls for secure code reviews as part of a continuous deployment program, as they have different meanings and functions. Detective controls are controls that aim to detect or discover undesirable events or outcomes that have occurred, such as errors, defects, or incidents. Logical controls are controls that use software or hardware mechanisms to regulate or restrict access to IT resources, such as data, systems, or networks. Corrective controls are controls that aim to correct or rectify undesirable events or outcomes that have occurred, such as errors, defects, or incidents. References: CISA Review Manual (Digital Version), Chapter 3, Section 3.2

 The auditor’s best course of action in this situation is to notify the audit manager. The audit manager is responsible for overseeing the audit follow-up process and ensuring that audit issues are resolved in a timely and satisfactory manner. The audit manager can then decide whether to escalate the matter to higher authorities, such as the chair of the audit committee, or to accept management’s decision and close the audit finding. The other options are not appropriate for the auditor to do without consulting with the audit manager first. Notifying the chair of the audit committee is a drastic step that may undermine the relationship between the auditor and management, and it should be done only after exhausting other means of resolving the issue. Retesting the control is not necessary, as management has already decided not to implement therecommendations. Closing the audit finding is premature, as management’s decision may not be aligned with the audit objectives or risk appetite. References: CISA Review Manual (Digital Version), Chapter 2, Section 2.4

 The primary basis for selecting which IS audits to perform in the coming year is the organizational risk assessment. An organizational risk assessment is a formal process for identifying, evaluating, and controlling risks that may affect the achievement of the organization’sgoals and objectives3. An organizational risk assessment can help IS auditors prioritize and plan their audit activities based on the level of risk exposure and impact of each area or process within the organization. An organizational risk assessment can also help IS auditors align their audit objectives and criteria with the organization’s strategy and performance indicators. Senior management’s request, prior year’s audit findings, and previous audit coverage and scope are also possible bases for selecting which IS audits to perform in the coming year, but not as primary as the organizational risk assessment. These factors are more secondary or supplementary sources of information that can help IS auditors refine or adjust their audit plan based on specific needs or issues identified by management or previous audits. However, thesefactors may not reflect the current or emerging risks that may affect the organization’s operations or performance. References: ISACA CISA Review Manual 27th Edition, page 295

 The strategy that would provide the greatest assurance of system quality at implementation is delivering only the core functionality on the initial target date. This strategy can help avoid compromising the quality of the system by focusing on the essential features that meet the user needs and expectations. Delivering only the core functionality can also help reduce the scope creep, complexity, and testing efforts of the system development project.

Implementing overtime pay and bonuses for all development staff, utilizing new system development tools to improve productivity, and recruiting IS staff to expedite system development are not strategies that would provide the greatest assurance of system quality at implementation. These strategies may help speed up the system development process, but they may also introduce new risks or challenges such as burnout, learning curve, integration issues, or communication gaps. These risks or challenges may adversely affect the quality of the system.

 Data analytics can be used to compare data from different sources and identify any discrepancies or anomalies. In this case, comparing a population of loans input in the origination system to loans booked on the servicing system can help detect any errors or frauds in the loan origination process. The other options are not examples of data analytics, but rather controls for data integrity, reconciliation, and error handling. References: CISA Review Manual (Digital Version), Chapter 3, Section 3.3.2

The IS auditor’s best course of action if they suspect an organization’s computer may have been used to commit a crime is to contact the incident response team to conduct an investigation. The incident response team is a group of experts who are responsible for responding to security incidents, such as data breaches, ransomware attacks, or cybercrimes. The incident response team can help to preserve and collect digital evidence, determine the scope and impact of the incident, contain and eradicate the threat, and restore normal operations. The IS auditor should not examine the computer themselves, as they may inadvertently alter or destroy potential evidence, or compromise the chain of custody. The IS auditor should also not notify local law enforcement before further investigation, as this may escalate the situation unnecessarily or interfere with the internal investigation process. The IS auditor should advise management of the crime after the investigation, or as soon as possible if there is an imminent risk or legal obligation to do so.

The most effective control for protecting the confidentiality and integrity of data stored unencrypted on virtual machines is to monitor access to stored images and snapshots of virtual machines. Images and snapshots are copies of virtual machines that can be used for backup, restoration, or cloning purposes. If data stored on virtual machines are unencrypted, they may be exposed or compromised if unauthorized or malicious users access or copy the images or snapshots. Therefore, monitoring access to stored images and snapshots can help detect and prevent any unauthorized or suspicious activities, and provide audit trails for accountability and investigation.

Restricting access to images and snapshots of virtual machines, limiting creation of virtual machine images and snapshots, and reviewing logical access controls on virtual machines regularly are not the most effective controls for protecting the confidentiality and integrity of data stored unencrypted on virtual machines. These controls may help reduce the risk or impact of data exposure or compromise, but they do not provide sufficient visibility or assurance of data protection. Restricting access to images and snapshots may not prevent authorized users from abusing their privileges or credentials. Limiting creation of virtual machine images and snapshots may not address the existing copies that may contain sensitive data. Reviewing logical access controls on virtual machines regularly may not reflect the actual access activities on images and snapshots.

 The effectiveness of a risk management program can be measured by how well it reduces the residual risk, which is the risk that remains after applying controls, to an acceptable level. Inherent risk is the risk that exists before applying any controls, and it cannot be eliminated completely. Control risk is the risk that the controls fail to prevent or detect a risk event, and it is a component of residual risk. Overall risk is not a meaningful metric for assessing the effectiveness of a risk management program, as it does not account for the impact and likelihood of different risk events. References: CISA Review Manual (Digital Version), Chapter 1, Section 1.2.2

Reviewing input and output control reports to verify the accuracy of the system decisions is the most important procedure for the IS auditor to perform during the post-implementation review of intelligent-agent software for granting loans to customers, because it can help identify any errors or anomalies in the system logic or data that may affect the quality and reliability of the system outcomes. Reviewing systemand error logs, signed approvals, and systemdocumentation are also important procedures, but they are not as critical as verifying the accuracy of the system decisions. References: CISA Review Manual (Digital Version), Chapter 4, Section 4.2.21

Requirements analysis should be the best thing to compare against the business case when determining whether a project in the design phase will meet organizational objectives, because it defines the functional and non-functional specifications of the project deliverables that should satisfy the business needs and expectations. Requirements analysis can help evaluate whether the project design is aligned with the business case and whether it can achieve the desired outcomes and benefits. Implementation plan, project budget provisions, and project plan are also important aspects of a project in the design phase, but they are not as relevant asrequirements analysisfor comparing against the business case. References: CISA Review Manual (Digital Version), Chapter 4, Section 4.2.1

The IS auditor’s best course of action in this situation is to present observations for discussion only. Observations are factual statements or findings that are based on the audit evidence collected and analyzed during the audit. Observations can be presented to management for discussion and feedback, but they should not be considered as final conclusions or recommendations until the audit is completed and the audit report is issued. The other options are not appropriate for presenting the findings to date, as they may compromise the audit quality or integrity. Reviewing working papers with the auditee is not advisable, as working papers are confidential documents that contain the auditor’s notes, calculations, and opinions that may not be relevant or accurate for management’s review. Requesting the auditee provide management responses is premature, as management responses should be obtained after the audit report is issued and the audit findings andrecommendations are finalized. Requesting management wait until a final report is ready for discussion is impractical, as management may have a legitimate interest or need to know the audit progress and results as soon as possible. References: CISA Review Manual (Digital Version), Chapter 2, Section 2.3

 A business continuity plan (BCP) is a system of prevention and recovery from potential threats to a company. The plan ensures that personnel and assets are protected and are able to function quickly in the event of a disaster1. A core part of a BCP is the documentation of workaround processes to keep a business function operational during recovery of IT systems. Workaround processes are alternative methods or procedures that can be used to perform a business function when the normal IT systems are unavailable or disrupted2. For example, if an online payment system is down, a workaround process could be to accept manual payments or use a backup system. Workaround processes help to minimize the impact of IT disruptions on the business operations and ensure continuity of service to customers and stakeholders3.

The most important thing for an IS auditor to review when evaluating the accuracy of a spreadsheet that contains several macros is the formulas within macros. Macros are sequences of commands or instructions that can automate tasks or calculations in a spreadsheet. Formulas are expressions that perform calculations on values or data in a spreadsheet. The accuracy of a spreadsheet depends largely on whether the formulas within macros are correct, consistent, and complete. The IS auditor should review the formulas within macros to verify that they produce the expected results and do not contain any errors or inconsistencies. The other options are not as important as formulas within macros, as they do not directly affect the accuracy of a spreadsheet. Encryption of the spreadsheet is a security control that can protect the confidentiality and integrity of the spreadsheet, but it does not ensure its accuracy. Version history is a document control feature that can track and manage changes to the spreadsheet, but it does not verify its accuracy. Reconciliation of key calculations is a validation technique that can compare and confirm the results of calculations with other sources, but it does not evaluate the accuracy of formulas within macros. References: CISA Review Manual (Digital Version), Chapter 3, Section 3.2

Reviewing and evaluating application test cases is the most effective use of an IS auditor’s time during the evaluation of controls over a major application development project. Application test cases are designed to verify that the application meets the functional and non-functional requirements and specifications. They also help to identify and correct any errors, defects, or vulnerabilities in the application before it is deployed. By reviewing and evaluating the test cases, the IS auditor can assess the quality, reliability, security, and performance of the application and provide recommendations for improvement. 

Application level firewalls are the best control to prevent the transfer of files to external parties through instant messaging (IM) applications, because they can inspect and filter network traffic based on application-specific protocols and commands, such as IM file transfer commands. Application level firewalls can block or allow IM file transfers based on predefined rules or policies. File level encryption, file transfer protocol (FTP), and instant messaging policy are not effective controls to prevent IM file transfers, because they donot restrict or monitor IM network traffic. References: CISA Review Manual (Digital Version), Chapter 5, Section 5.4.1

 Fine tuning the intrusion detection system (IDS) is the best recommendation to reduce the number of false positive alerts that overwhelm the log management system, because it can help adjust the sensitivity and accuracy of the IDS rules and signatures to match the network environment and traffic patterns. Establishing criteria for reviewing alerts, recruiting more monitoring personnel, and reducing thefirewall rules are not effective solutions to address theroot cause of the false positive alerts, but rather ways to cope with the consequences. References: CISA Review Manual (Digital Version), Chapter 5, Section5.4.3

 The first course of action when a data breach has occurred due to malware is to quarantine the impacted systems. This means isolating the infected systems from the rest of the network and preventing any further communication or data transfer with them. This can help contain the spread of the malware, limit the damage and exposure of sensitive data, and facilitate the investigation and remediation of the incident. Quarantining the impacted systems can also help preserve the evidence and logs that may be needed for forensic analysis or legal action.

The best method to prevent wire transfer fraud by bank employees is system-enforced dual control. System-enforced dual control is a segregation of duties control that requires two or more individuals to perform or authorize a transaction or activity using a system that enforces this requirement. System-enforced dual control can prevent wire transfer fraud by requiring independent verification and approval of payment requests, amounts, and recipients by different bank employees using a system that does not allow any single employee to complete the transaction alone. The other options are not as effective as system-enforced dual control in preventing wire transfer fraud, as they do not involve independent checks or approvals using a system. Independent reconciliation is a detective control that can help compare and confirm payment records with bank statements, but it does not prevent wire transfer fraud from occurring. Re-keying of wire dollar amounts is an input control that can help detect any errors or discrepancies in payment amounts, but it does not prevent wire transfer fraud from occurring. Two-factor authentication control is an access control that can help verify the identity and authorization of bank employees, but it does not prevent wire transfer fraud from occurring. References: CISA Review Manual (DigitalVersion), Chapter 3, Section 3.2

 The most important thing to include in forensic data collection and preservation procedures is preserving data integrity. Data integrity is the property that ensures that data is accurate, complete, and consistent throughout its lifecycle. Preserving data integrity is essential for forensic data collection and preservation procedures because it ensures that the data can be used as valid and reliable evidence in legal proceedings or investigations. Preserving data integrity can be achieved by using methods such as hashing, checksums, digital signatures, write blockers, tamper-evident seals, or timestamps. The other options are not as important as preserving data integrity in forensic data collection and preservation procedures, as they do not affect the validity or reliability of the data. Assuring the physical security of devices is a security measure that protects devices from unauthorized access, theft, damage, or destruction, but it does not ensure that the data on the devices is accurate, complete, and consistent. Maintaining chain of custody is a documentation technique that records and tracks the handling and transfer of devices or data among different parties involved in forensic activities, but it does not ensure that the data on the devices is accurate, complete, and consistent. Determining tools to be used is a planning activity that selects and prepares the appropriate tools for forensic data collection and preservation procedures, but it does not ensure that the data collected and preserved by the tools is accurate, complete, and consistent. References: CISA Review Manual (Digital Version), Chapter 5, Section 5.4

The best way to assess the effectiveness of changes made to processes and tools related to an organization’s BCP is to review the full test results of the BCP. Full test results can provide evidence of whether the changes have improved the BCP’s objectives, such as recovery time objectives (RTOs), recovery point objectives (RPOs), and business impact analysis (BIA). The other options are not as effective as reviewing the full test results, as they do not demonstrate the actual performance of the BCP under simulated disaster scenarios. Completed test plans are only documents that outline the scope, objectives, and procedures of the BCP testing, but they do not show the outcomes or issues encountered during the testing. Updated inventory of systems is a component of the BCP that identifies the critical systems and resources required for business continuity, but it does not measure the effectiveness of the BCP changes. Change management processes are controls that ensure that changes to the BCP are authorized, documented, and communicated, but they do not evaluate the impact or benefit of the changes. References: CISA Review Manual (Digital Version), Chapter 4, Section 4.2.3

 Information security policies are high-level statements that define the organization’s approach to protecting its information assets from threats and risks. They should be based primarily on a risk management process, which is a systematic method of identifying, analyzing, evaluating, treating, and monitoring information security risks. A risk management process can help ensure that the policies are aligned with the organization’s risk appetite, business objectives, legal and regulatory requirements, and stakeholder expectations. An information security framework is a set of standards, guidelines, and best practices that provide a structure for implementing information security policies. It can support the risk management process, but it is not the primary basis for defining the policies. Past information security incidents and industry best practices can also provide valuable inputs for defining the policies, but they are not sufficient to address the organization’s specific context and needs. References: Insights and Expertise, CISA Review Manual (Digital Version)

 The best compensating control when segregation of duties is lacking in a small IS department is transaction log review. Transaction log review can help detect any unauthorized or fraudulent activities performed by IS staff who have access to multiple functions or systems. Transaction log review can also provide an audit trail for accountability and investigation purposes. The other options are not as effective as transaction log review in compensating for the lack of segregation of duties. Background checks are preventive controls that can help screen potential employees for any criminal records or dishonest behavior, but they do not prevent existing employees from abusing their access privileges. User awareness training is a detective control that can help educate users on how to report any suspicious or abnormal activities in the IS environment, but it does not monitor or verify the actions of IS staff. Mandatory holidays are deterrent controls that can discourage IS staff from engaging in fraudulent activities by requiring them to take periodic leave, but they do not prevent or detect such activities when they occur. References: CISA Review Manual (Digital Version), Chapter 3, Section 3.2

The best guard against the risk of attack by hackers is encryption. Encryption is the process of transforming data into an unreadable format using a secret key or algorithm. Encryption can protect data in transit and at rest from unauthorized access, modification, or disclosure by hackers. Encryption can also ensure the authenticity and integrity of data by using digital signatures or hashes.

Tunneling, message validation, and firewalls are not the best guards against the risk of attack by hackers. Tunneling is a technique that encapsulates one network protocol within another to create a secure connection between two endpoints. Message validation is a process that verifies the format, content, and origin of a message before accepting it. Firewalls are devices or software that filter network traffic based on predefined rules. These controls may help reduce the exposure or impact of hacker attacks, but they do not provide the same level of protection as encryption.

 If an IS auditor finds that management did not address a prior period audit finding, the next course of action should be to interview management to determine why the finding was not addressed, as this would help to understand the root cause, the impact, and the risk level of the issue. Noting the exception in a new report, recommending alternative solutions, or conducting a risk assessment are possible subsequent steps, but they should not precede interviewing management. References: CISA Review Manual (Digital Version), Chapter 1, Section 1.6

 An organization’s audit charter primarily describes the auditors’ authority to conduct audits. The audit charter is a formal document that defines the purpose, scope, responsibilities, and reporting relationships of the internal audit function. It also establishes the auditors’ right of access to information, records, personnel, and physical properties relevant to their work. The audit charter provides the basis for the auditors’ independence and accountability to the governing body and senior management. 

 A black box penetration test is a type of security assessment that simulates an attack on a system or network without any prior knowledge of its configuration or architecture. The main objective of this test is to identify vulnerabilities and weaknesses that can be exploited by external or internal threat actors. To plan a black box penetration test, it is most important to ensure that the environment and penetration test scope have been determined. This means that the tester and the client organization have agreed on the boundaries, objectives, methods, and deliverables of the test, as well as the legal and ethical aspects of the engagement. Without a clear definition of the environment and scope, the test may not be effective, efficient, or compliant with relevant standards and regulations. Additionally, the tester may cause unintended damage or disruption to the client’s systems or networks, or violate their privacy or security policies.

 During an audit of a reciprocal disaster recovery agreement between two companies, the IS auditor would be most concerned with the allocation of resources during an emergency. A reciprocal disaster recovery agreement is an arrangement by which one organization agrees to use another’s resources in the event of a business continuity event or incident. The IS auditor would need to ensure that both parties have clearly defined their roles and responsibilities, their resource requirements, their priority levels, their communication channels, and their escalation procedures in case of a disaster. The IS auditor would also need to verify that both parties have tested their agreement and have updated it regularly to reflect any changes in their business environments. The frequency of system testing is not as critical as the allocation of resources during an emergency, because system testing can be performed periodically or on demand, while resource allocation is a dynamic and complex process that requires careful planning and coordination. The differences in IS policies and procedures are not as critical as the allocation of resources during an emergency, because both parties can agree on common standards and protocols for their disaster recovery operations, or they can adapt their policies and procedures to suit each other’s needs. The maintenance of hardware and software compatibility is not as critical as the allocation of resources during an emergency, because both parties can use compatible or interoperable systems, or they can use virtualization or cloud computing technologies to overcome any compatibility issues. References: ISACACISA Review Manual 27th Edition, page 281

The best recommendation to prevent fraudulent electronic funds transfers by accounts payable employees is dual control. Dual control is a segregation of duties control that requires two or more individuals to perform or authorize a transaction or activity. Dual control can prevent fraudulent electronic funds transfers by requiring independent verification and approval of payment requests, amounts, and recipients by different accounts payable employees. The other options are not as effective as dual control in preventing fraudulent electronic funds transfers, as they do not involve independent checks or approvals. Periodic vendor reviews are detective controls that can help identify any irregularities or anomalies in vendor payments, but they do not prevent fraudulent electronic funds transfers from occurring. Independent reconciliation is a detective control that can help compare and confirm payment records with bank statements, but it does not prevent fraudulent electronic funds transfers from occurring. Re-keying of monetary amounts is an input control that can help detect any errors or discrepancies in payment amounts, but it does not prevent fraudulentelectronic funds transfers from occurring. References: CISA Review Manual (Digital Version), Chapter 3, Section 3.2

Risk-based auditing is an audit approach that focuses on the analysis and management of risk within an organization. Risk-based auditing helps identify and prioritize the areas or processes that pose the highest risk to the organization’s objectives and allocate audit resources accordingly. Risk-based auditing also helps provide assurance and advisory services related to the organization’s risk management processes and controls. By using risk-based auditing, internal auditors can optimize the use of their audit resources and add value to the organization.

Agile auditing, continuous auditing, and outsourced auditing are not audit approaches that are most helpful in optimizing the use of IS audit resources. Agile auditing is a flexible and iterative audit methodology that adapts to changing circumstances and stakeholder needs. Continuous auditing is a method of performing audit activities on a real-time or near-real-time basis using automated tools and techniques. Outsourced auditing is a practice of contracting external auditors to perform some or all of the internal audit functions. These audit methods may have some advantages or disadvantages depending on the context and objectives of the audit, but they do not necessarily optimize the use of IS audit resources.

One benefit of return on investment (ROI) analysis in IT decision making is that it provides the basis for allocating financial resources. ROI analysis is a method of evaluating the profitability or cost-effectiveness of an IT project or investment by comparing the expected benefits with the required costs. ROI analysis can help IT decision makers prioritize and justify their IT initiatives, allocate their financial resources optimally, and demonstrate the value contribution of IT to the organization’s goals and objectives. Basis for allocating indirect costs, cost of replacing equipment, and estimated cost of ownership are not benefits of ROI analysis in IT decision making. These are more inputs or outputs of ROI analysis that could be used to calculate or estimate the costs or benefits of an IT project or investment. References: [ISACA CISA Review Manual 27th Edition], page 307

The most effective method to verify that a service vendor keeps control levels as required by the client is to conduct periodic on-site assessments using agreed-upon criteria. On-site assessments can provide direct evidence of whether the vendor’s controls are operating effectively and consistently in accordance with the client’s expectations and requirements. Agreed-upon criteria can ensure that the assessments are objective, relevant, and reliable. The other options are not as effective as on-site assessments in verifying the vendor’s control levels. Periodically reviewing the SLA with the vendor can help monitor whether the vendor meets its contractual obligations and service standards, but it does not provide assurance of whether the vendor’s controls are adequate or sufficient. Conducting an unannounced vulnerability assessment of vendor’s IT systems can help identify any weaknesses or gaps in the vendor’s security controls, but it may violate the terms and conditions of the vendor-client relationship or cause operational disruptions. Obtaining evidence of the vendor’s CSA can provide some indication of whether the vendor’s controls are self-monitored and reported, but it does not verify whether the vendor’s controls are independent or accurate. References: CISA Review Manual (Digital Version), Chapter 5, Section 5.4

 Secure coding practices are the best way to prevent cross-site scripting (XSS) attacks, because they can ensure that the web application validates and sanitizes user input and output data to prevent malicious scripts from being executed on the web browser. XSS attacks are a type of web application vulnerability that exploit the lack of input validation or output encoding in webpages that accept user input or display dynamic content. Application firewall policy settings, a three-tier web architecture, and use of common industry frameworks are not effective controlsto prevent XSS attacks, because they do not address the root cause of the vulnerability in the web application code. References: CISA Review Manual (Digital Version), Chapter 5, Section 5.4.2

 The best method to safeguard data on an organization’s laptop computers is full disk encryption. Full disk encryption is a technique that encrypts all the data stored on a harddrive, including the operating system, applications, files, and folders. This means that if the laptop is lost, stolen, or accessed by an unauthorized person, they will not be able to read or modify any data without knowing the encryption key or password. Full disk encryption provides a strong level of protection for data at rest, as it prevents data leakage or exposure in case of physical theft or loss of the device.

Moving validation controls from the server side into the browser would most likely increase the risk of a successful attack by structured query language (SQL) injection. SQL injection is a technique that exploits a security vulnerability in an application’s database layer by inserting malicious SQL statements into user input fields. Validation controls are used to check and filter user input before sending it to the database. If these controls are moved to the browser, they can be easily bypassed or modified by an attacker, who can then execute arbitrary SQL commands on the database. References: CISA Review Manual, 27th Edition, page 361

The most important control to assess in an audit of an organization’s accounts payable processes is segregation of duties between issuing purchase orders and making payments. Segregation of duties is a principle that requires different individuals or departments to perform different tasks or functions within a process, in order to prevent fraud, errors, or conflicts of interest. In the accounts payable process, segregation of duties between issuing purchase orders and making payments ensures that no one person can initiate and complete a transaction without proper authorization and verification. This reduces the risk of duplicate payments, overpayments, unauthorized payments, or payments to fictitious vendors.

The most concerning issue when determining if information assets are adequately safeguarded during transport and disposal is lack of appropriate data classification. Data classification is a process that assigns categories or levels of sensitivity to different types of information assets based on their value, criticality, or risk to the organization. Data classification can help safeguard information assets during transport and disposal by providing criteria and guidelines for identifying, labeling, handling, and protecting information assets according to their sensitivity. Lack of appropriate data classification can compromise the security and confidentiality of information assets during transport and disposal by exposing them to unauthorized access, disclosure, theft, damage, or destruction. The other options are not as concerning as lack of appropriate data classification in safeguarding information assets during transport and disposal, as they do not affect the identification, labeling, handling, or protection of information assets according to their sensitivity. Lack of appropriate labeling is a possible factor that may increase the risk of misplacing, losing, or mishandling information assets during transport and disposal, but it does not affect the classification of information assets according to their sensitivity. Lack of recent awareness training is a possible factor that may affect the knowledge or behavior of staff involved in transporting or disposing of information assets, but it does not affect the classification of information assets according to their sensitivity. Lack of password protection is a possible factor that may affect the security or confidentiality of information assets stored on devices during transport and disposal, but it does not affect the classification of information assets according to their sensitivity. References: CISA Review Manual (Digital Version), Chapter 5, Section 5.3.2

The first step when planning a penetration test is to obtain management consent for the testing. This is because a penetration test involves simulating a cyberattack against theorganization’s systems and networks, which may have legal, ethical, and operational implications. Without proper authorization from management, a penetration test may violate laws, policies, contracts, or service level agreements. Management consent also helps define the objectives, scope, and boundaries of the test, as well as the roles and responsibilities of the testers and the stakeholders. Obtaining management consent for the testing also demonstrates due care and due diligence on the part of the testers and the organization.

Executing nondisclosure agreements (NDAs), determining reporting requirements for vulnerabilities, and defining the testing scope are important steps when planning a penetration test, but they are not the first step. These steps should be done after obtaining management consent for the testing, as they depend on the approval and involvement of management and other parties.

The most important aspect of an application development acceptance test is that user management approves the test design before the test is started, as this ensures that the test objectives, criteria, and procedures are aligned with the user requirements and expectations. The programming team’s involvement in the testing process, the testing of data files for valid information before conversion, and the quality assurance (QA) team’s charge of the testing process are also important, but they are not as critical as user management’s approval of the test design. References: CISA Review Manual (Digital Version), Chapter 4, Section 4.4.2

The first step in addressing a vulnerability is to evaluate the associated risk, which involves assessing the likelihood and impact of a potential exploit. Based on the risk assessment, the appropriate mitigation strategy can be determined, such as implementing a new system, addingfirewalls, or decommissioning the server. References: ISACA CISA Review Manual 27th Edition, page 280

 The IS auditor’s independence would be most likely impaired if they implemented a specific control during the development of an application system. This is because the IS auditor would be auditing their own work, which creates a self-review threat that could compromise their objectivity and impartiality. The IS auditor should avoid participating in any operational or management activities that could affect their ability to perform an unbiased audit. The other options do not pose a significant threat to the IS auditor’s independence, as long as they follow the ethical standards and guidelines of the profession.

 Substantive testing provides the most reliable audit evidence on the validity of transactions in a financial application. Substantive testing is an audit procedure that examines the financial statements and supporting documentation to see if they contain errors or misstatements. Substantive testing can help to verify that the transactions recorded in the financial applicationare authorized, complete, accurate, and properly classified. Substantive testing can include methods such as vouching, confirmation, analytical procedures, or physical examination. 

 Input validation is the best control to address SQL injection vulnerabilities, because it can prevent malicious users from entering SQL commands or statements into input fields that are intended for data entry, such as usernames or passwords. SQL injection is a technique that exploits a security vulnerability in an application’s software by inserting SQL code into a query string that can execute commands on a database server. Unicode translation, SSL encryption, and digital signatures are not effectivecontrols against SQL injection, because they do not prevent or detect SQL code injection into input fields. References: CISA Review Manual (Digital Version), Chapter 5, Section 5.4.2

Reconciliation of total amounts by project is the best control to ensure that data is accurately entered into the job-costing system from spreadsheets. Reconciliation is a process of comparing two sets of data to identify any differences or discrepancies between them. By reconciling the total amounts by project from spreadsheets with those from the job-costing system, any errors or omissions in data entry can be detected and corrected. Validity checks are controls that verify that data conforms to predefined formats or ranges. They can prevent entry of character data into numeric fields, but they cannot ensure that the numeric data is correct or complete. Reasonableness checks are controls that verify that data is within expected or acceptable limits. They can detect outliers or anomalies in data, but they cannot ensure that the data matches the source. Display back of project detail after entry is a control that allows the user to review and confirm the data entered into the system. It can help reduce human errors, but it cannot guarantee that the data is accurate or consistent with the source. References: Information Systems Operations and Business Resilience, CISA Review Manual (Digital Version)

 The best recommendation to reduce the risk of data leakage from employee use of social networking sites for business purposes is to provide education and guidelines to employees on use of social networking sites. Education and guidelines can help employees understand the benefits and risks of using social media for business purposes, such as enhancing brand awareness, engaging with customers, or sharing industry insights. They can also inform employees about the dos and don’ts of social media etiquette, such as respecting privacy, protecting intellectual property, avoiding conflicts of interest, or complying with legal obligations. Education and guidelines can also raise awareness of potential data leakage scenarios, such as phishing attacks, malicious links, fake profiles, or oversharing sensitive information, and provide tips on how to prevent or respond to them. 

The IS auditor’s first course of action should be to verify the results of the critical automatic calculations made by the system to determine the validity of user concerns. This is because the IS auditor needs to obtain sufficient and appropriate audit evidence to support the audit findings and conclusions. By verifying the results, the IS auditor can assess whether there are any errors or discrepancies in the system’s calculations that could affect the accuracy and reliability of the financial data. The IS auditor can use various techniques to verify the results, such as re-performing the calculations, comparing them with expected values, or tracing them to source documents. 

 The best detective control for a job scheduling process involving data transmission is job failure alerts that are automatically generated and routed to support personnel. Job failure alerts are notifications that indicate when a scheduled job or task fails to execute or complete successfully, such as due to errors, interruptions, or delays. Job failure alerts can help detect and correct any issues or anomalies in the job scheduling process involving data transmission by informing and alerting the support personnel who can investigate and resolve the problem. The other options are not as effective as job failure alerts in detecting issues or anomalies in the job scheduling process involving data transmission, as they do not provide timely or specific information or feedback. Metrics denoting the volume of monthly job failures are reported and reviewed by senior management is a reporting technique that can help measure and improve the performance and reliability of the job scheduling process, but it does not provide immediate or detailed information on individual job failures. Jobs are scheduled to be completed daily and data is transmitted using a Secure File Transfer Protocol (SFTP) is a preventive control that can help ensure the timeliness and security of the job scheduling process involving data transmission, but it does not detect any issues or anomalies that may occur during the process. Jobs are scheduled and a log of this activity is retained for subsequent review is a logging technique that can help record and track the status and results of the job scheduling process involving data transmission, but it does not provide real-time or proactive information on job failures. References: CISA Review Manual (Digital Version), Chapter 3, Section 3.2

The best testing approach to facilitate rapid identification of application interface errors is automated testing. Automated testing is the use of software tools or scripts to execute predefined test cases, compare expected and actual outcomes, and report any discrepancies. Automated testing can help to speed up the testing process, increase test coverage, reduce human errors, and improve test accuracy and consistency. Automated testing can also help to detect interface errors that may occur due to incompatible data formats, communication protocols, or system configurations. References:

CISA OnlineReview Course, Domain 2, Module 2, Lesson 1

The most important thing for the IS auditor to determine in a post-implementation review of a recently purchased system is whether the user requirements were met. User requirements are the specifications and expectations of the users of the system, such as the features, functions, performance, quality, and security of the system. User requirements are usually defined and documented in the early stages of the system acquisition process, such as in the request for proposal (RFP) or the contract. User requirements are also used as the basis for testing and evaluating the system before and after implementation.

Determining whether the user requirements were met can help the IS auditor assess whether the system is fit for purpose and delivers value and benefits to the users and the organization. Determining whether the user requirements were met can also help the IS auditor identify any gaps, issues, or problems with the system that may affect its functionality, usability, or reliability. Determining whether the user requirements were met can also help the IS auditor provide feedback and recommendations for improvement or enhancement of the system.

Stakeholder expectations were identified is not the most important thing for the IS auditor to determine in a post-implementation review of a recently purchased system, but rather a prerequisite or input for it. Stakeholder expectations are the needs and wants of the various parties who have an interest or influence in the system, such as users, managers, customers, suppliers, regulators, or auditors. Stakeholder expectations are usually identified and analyzed in the initial stages of the system acquisition process, such as in the feasibility study or the business case. Stakeholder expectations are also used as inputs for defining and prioritizing the user requirements.

Vendor product offered a viable solution is not the most important thing for the IS auditor to determine in a post-implementation review of a recently purchased system, but rather an outcome or result of it. Vendor product is the system that is provided by an external supplier or service provider to meet the user requirements. Vendor product offered a viable solution means that the vendor product satisfied or exceeded the user requirements and delivered value and benefits to the users and organization. Vendor product offered a viable solution can be determined by comparing and evaluating the user requirements and the vendor product performance and quality.

Test scenarios reflected operating activities is not the most important thing for the IS auditor to determine in a post-implementation review of a recently purchased system, but rather a factor or criterion for it. Test scenarios are sets of conditions or situations that are used to test and verify whether the system meets the user requirements. Test scenarios reflected operating activities means that test scenarios simulated or replicated real-world scenarios that occur during normal operations of business processes or functions that use or depend on the system. Test scenarios reflected operating activities can help ensure that test results are valid, reliable, and relevant.

A business impact analysis (BIA) is a process that identifies and evaluates the potential effects of disruptions to critical business operations as a result of a disaster, accident or emergency. A BIA should include an inventory of relevant business processes that support the organization’s strategic objectives and are essential for its continuity. The inventory should also identify the dependencies, interdependencies, recovery priorities and time frames for each business process. Policies for business procurement, documentation of application configurations and results of business resumption planning efforts are not as useful as an inventory of relevant business processes for performing a BIA. References:

 The best source of information to determine the required level of data protection on a file server is the data classification policy and procedures, which define the criteria and methods for classifying data according to its sensitivity, value, and criticality, and specify the appropriate security measures and controls for each data category. Data classification policy and procedures help to ensure that data is protected in proportion to its importance and risk exposure. Access rights of similar file servers, previous data breach incident reports,and acceptable use policy and privacy statements are not sufficient or reliable sources of information to determine the required level of data protection on a file server, as they do not provide clear and consistent guidance on how to classify and protectdata. References: CISA Review Manual (Digital Version), Chapter 5: Protection of Information Assets, Section 5.1: Information Asset Security Framework

 IT performance measures are indicators of how well an organization is achieving its IT goals and objectives. Benchmarking surveys are useful tools for comparing an organization’s IT performance measures with those of other organizations in the same industry or sector. Benchmarking surveys can provide insights into best practices, gaps, trends, and opportunities for improvement. IT governance frameworks, utilization reports, and balanced scorecards are not as helpful for comparing ITperformance measures across organizations, as they may vary in scope, methodology, and terminology. References: IT Resources | Knowledge & Insights | ISACA, CISA Review Manual (Digital Version)

The lack of system documentation should be of most concern to an IS auditor reviewing the information systems acquisition, development, and implementation process. This is because system documentation is a vital source of information that describes the system’s purpose, functionality, design, architecture, testing, deployment, operation, and maintenance. System documentation helps the IS auditor to understand and evaluate the system’s quality, performance, security, compliance, and alignment with the business requirements and objectives. Without system documentation, the IS auditor may not be able to perform a thorough and effective audit of the system, aswell as identify any issues or risks that may affect the system’s reliability or integrity12.

Data owners are not trained on the use of data conversion tools is not the most concerning issue, although it may indicate a lack of user readiness or competence for the system implementation. Data conversion tools are software applications that help users to transform data from one format or structure to another, such as from legacy systems to new systems. Data owners are users who have the responsibility and authority to manage and control the data within their domain. Data owners should be trained on how to use data conversion tools to ensure that the data is accurately and securely transferred to the new system, as well as to avoid any data loss, corruption, or inconsistency. However, data owners are not the only users who need training for the system implementation, and data conversion tools are not the only tools that need training34.

A post-implementation lessons-learned exercise was not conducted is not the most concerning issue, although it may indicate a lack of continuous improvement or learning culture for the system development and implementation process. A post-implementation lessons-learned exercise is a meeting or a session that takes place after the completion of a system implementation project, where the project team and stakeholders discuss and document the successes and failures of the project, as well as identify any best practices or areas for improvement for future projects. Apost-implementation lessons-learned exercise can help to enhance the project management skills, knowledge, and performance of the project team and stakeholders, as well as to avoid repeating the same mistakes or problems in future projects56.

System deployment is routinely performed by contractors is not the most concerning issue, although it may pose some challenges or risks for the system implementation process. System deployment is the final stage of the system development life cycle (SDLC), where the system is installed and configured on the target environment and made available for use by end-users. System deployment can be performed by internal staff or external contractors, depending on the availability, expertise, and cost of resources. System deployment by contractors may offer some benefits such as faster delivery, lower cost, or higher quality than internal staff. However, system deployment by contractors mayalso introduce some risks such as loss of control, dependency, or security breaches over the system implementation process

 A disaster recovery plan (DRP) is a set of detailed, documented guidelines that outline a business’ critical assets and explain how the organization will respond to unplanned incidents. Unplanned incidents or disasters typically include cyberattacks, system failures, power outages, natural disasters, equipment failures, or infrastructure damage1. A DRP aims to minimize the impact of a disaster on the business continuity, data integrity, and service delivery of the organization. A DRP also helps the organization recover from a disaster as quickly and efficiently as possible.

A DRP should include steps for obtaining replacement supplies, as this is an essential part of restoring the normal operation of the organization after a disaster. Replacement supplies may include hardware, software, data, network components, office equipment, or other resources that are needed to resume the business functions and processes that were disrupted by the disaster. Obtaining replacement supplies may involve contacting vendors, suppliers, or partners; activating backup or alternative systems; or purchasing or renting new equipment. A DRP should identify the sources, locations, and costs of the replacement supplies, as well as the procedures and responsibilities for acquiring and installing them.

The other three options are not steps that a DRP should include, as they are either part of the pre-disaster planning process or not directly related to the disaster recovery objectives. Assessing and quantifying risk is a step that should be done before creating a DRP, as it helps identify the potential threats and vulnerabilities that could affect the organization and determine the likelihood and impact of each scenario2. Negotiating contracts with disaster planning consultants is also a pre-disaster activity that may help the organization design, implement, test, and maintain a DRP with external expertise and guidance3. Identifying application control requirements is not a step in a DRP, but rather a part of the application development and maintenance process that ensures the quality, security, and reliability of the software applications used by the organization.

Therefore, obtaining replacement supplies is the correct answer.

The primary advantage of using virtualization technology for corporate applications is to achieve better utilization of resources, such as hardware, software, network and storage. Virtualization technology allows multiple applications to run on a single physical server or device, which reduces the need for additional hardware and maintenance costs. Virtualization technology also enables dynamic allocation and reallocation of resources according to the demand and priority of the applications, which improves efficiency and flexibility. The other options are not the primary advantage of using virtualization technology, although they may be some of the benefits or challenges depending on the implementation and configuration. References:

A database administrator (DBA) is responsible for maintaining the integrity, security and performance of the database systems. A DBA who is also responsible for developing and executing changes into the production environment may have a conflict of interest and pose a risk to the data quality and availability. Therefore, the IS auditor should first identify whether any compensating controls exist to mitigate this risk, such as independent reviews, approvals, audits or monitoring of the changes. Determining whether another DBA could make the changes, reporting a potential segregation of duties violation and ensuring a change management process is followed prior to implementation are possible actions that the auditor could take after identifying the compensating controls or the lack thereof. References:

The best recommendation to include in an organization’s bring your own device (BYOD) policy to help prevent data leakage is to require multi-factor authentication on BYOD devices. BYOD is a practice that allows employees to use their own personal devices, such as smartphones, tablets, or laptops, to access the organization’s network, data, and systems. Data leakage is a risk that involves the unauthorized or accidental disclosure or transfer of sensitive or confidential data from the organization to external parties or devices. Multi-factor authentication is a security measure that requires users to provide two or more pieces of evidence to verify their identity and access rights, such as passwords, tokens, biometrics, or codes. Multi-factor authentication can help prevent data leakage by reducing the likelihood of unauthorized access to the organization’s data and systems throughBYOD devices, especially if they are lost, stolen, or compromised. The other options are not as effective as requiring multi-factor authentication on BYOD devices, because they either do not prevent data leakage directly, or they are reactive rather than proactive measures. References: CISA Review Manual (Digital Version)1, Chapter 5, Section 5.2.3

 Internet Protocol (IP) address restrictions are used in a firewall to protect the entity’s internal resources by allowing or denying access to specific IP addresses or ranges of IP addresses based on predefined rules. Remote access servers, Secure Sockets Layers (SSLs), and failover services are not directly related to firewall protection, but rather to other aspects of network security, such as authentication, encryption, and availability. References: CISA Review Manual (Digital Version), Chapter 5: Protection of Information Assets, Section 5.2: Network Security Devices and Technologies

The audit finding that should be of greatest concern is that tasks defined on the critical path do not have resources allocated, as this means that the project is likely to face significant delays and cost overruns, since the critical path is the sequence of activities that determines the minimum time required to complete the project. The actual start times of some activities being later than originally scheduled may indicate some minor deviations from the project plan, but they may not necessarily affect the overall project completion time if they are not on the critical path. The project manager lacking formal certification may affect the quality and efficiency of the project management process, but it does not necessarily imply that the project manager is incompetent or unqualified. Milestones have been defined for all project products, but they may not be realistic or achievable if they do not take into account the resource constraints and dependencies of the critical path tasks. References: CISA Review Manual (Digital Version), Chapter 2: Governance and Management of IT, Section 2.3: IT Project Management

The first step in auditing a data communication system is to determine the business use and types of messages to be transmitted. This is because the auditor needs to understand the purpose, scope, and objectives of the data communication system, as well as the nature, volume, and sensitivity of the data being transmitted. This will help the auditor to identify the risks, controls, and audit criteria for the data communication system. Traffic volumes and response-time criteria, physical security for network equipment, and the level of redundancy in the various communication paths are important aspects of a data communication system, but they are not the first step in auditing it. They depend on the business use and types of messages to be transmitted, and they may vary according to different scenarios and requirements. References: CISA Review Manual (Digital Version), [ISACA Auditing Standards]

An IS auditor reviewing the threat assessment for a data center would be most concerned if all identified threats relate to external entities. This indicates that the threat assessment is incomplete and biased, as it ignores the potential threats from internal sources, such as employees, contractors, vendors, or authorized visitors. Internal threats can pose significant risks to the data center, as they may have access to sensitive information, systems, or facilities, and may exploit their privileges for malicious or fraudulent purposes. According to a study by IBM, 60% of cyberattacks in 2015 were carried out by insiders1

Some of the identified threats are unlikely to occur is not a cause for concern, as it shows that the threat assessment is comprehensive and realistic, and considers all possible scenarios, regardless of their probability. A threat assessment should not exclude any potential threats based on subjective judgments or assumptions, as they may still have a high impact if they materialize.

The exercise was completed by local management is not a cause for concern, as it shows that the threat assessment is conducted by the people who are most familiar with the data center’s operations, environment, and risks. Local management may have more relevant and accurate information and insights than external parties, and may be more invested in the outcome of the threat assessment.

Neighboring organizations’ operations have been included is not a cause for concern, as it shows that the threat assessment is holistic and contextual, and considers the interdependencies and influences of external factors on the data center’s security. Neighboring organizations’ operations may pose direct or indirect threats to the data center, such as physical damage, network interference, or shared vulnerabilities.

Full disk encryption (FDE) is a means of protecting information by encrypting all of thedata on a disk, including temporary files, programs, and system files1. FDE is best suited for addressing the risk scenario of physical theft of media on which information is stored, as it prevents unauthorized access to the data even if the device is lost or stolen2. FDE does not prevent data leakage as a result of employees leaving to work for competitors, as they may still have access to the data while using the device or copy the data to another device before leaving. FDE does not prevent noncompliance fines related to storage of regulated information, as it does not ensure that the data is stored in accordance with the applicable laws and regulations. FDE does not prevent unauthorized logical access to information through an application interface, as it does not control the access rights and permissions of users and applications. *References: According to the ISACA IT Audit and Assurance Standards, Guidelines and Tools and Techniques for IS Audit and Assurance Professionals, section 2402 Planning, “The IS audit and assurance professional should identify and assess risk relevant to the area under review.” 3 Oneof the risk factors to consider is “the sensitivity of information processed, stored or transmitted by the system” 3. FDE is one of the possible controls to mitigate the risk of unauthorized disclosure of sensitive information due to physical theft of media.

The greatest advantage of vulnerability scanning over penetration testing is that the testing process can be automated to cover large groups of assets. Vulnerability scanning is an automated, high-level security test that reports its findings of known vulnerabilities in systems, networks, applications, and devices. Vulnerability scanning can be performed frequently, quickly, and efficiently to scan a large number of assets and identify potential weaknesses that need to be addressed. Vulnerability scanning can also help organizations comply with security standards and regulations, such as PCI DSS1.

The other options are not as advantageous as option D, as they may not reflect the true benefits or limitations of vulnerability scanning compared to penetration testing. The testing produces a lower number of false positive results, but this is not necessarily true, as vulnerability scanning may report vulnerabilities that are not exploitable or relevant in the context of the organization. Network bandwidth is utilized more efficiently, but this may not be a significant advantage, as vulnerability scanning may still consume considerable network resources depending on the scope and frequency of the scans. Custom-developed applications can be tested more accurately, but this is also not true, as vulnerability scanning may not be able to detect complex or unknown vulnerabilities that require manual analysis or exploitation.

The first thing that an IS auditor should recommend when an organization is made aware of a new regulation that is likely to impact IT security requirements is to determine which systems and IT-related processes may be impacted. This is because the impact assessment is a crucial step to understand the scope and magnitude of the changes that the new regulation may entail, as well as the potential risks and gaps that need to be addressed. The impact assessment can help the organization to prioritize and plan the necessary actions and resourcesto comply with the new regulation in a timely and effective manner12.

Updating security policies based on the new regulation is not the first thing to do, because it requires a clear understanding of the impact and implications of the new regulation, which can only be obtained after conducting an impact assessment. Updating security policies without an impact assessment may result in incomplete, inconsistent, or ineffective policies that may not meet the regulatory requirements or the organizational needs12.

Evaluating how security awareness and training content may be impacted is not the first thing to do, because it is a secondary or supporting activity that depends on the results of the impact assessment and the policy updates. Evaluating security awareness and training content without an impact assessment or policy updates may result in inaccurate, outdated, or irrelevant content that may not reflect the regulatory requirements or the organizational expectations34.

Reviewing the design and effectiveness of existing IT controls is not the first thing to do, because it is a monitoring or assurance activity that follows the implementation of the changes based on the impact assessment and the policy updates. Reviewing IT controls without an impact assessment or policy updates may result in misleading, incomplete, or invalidfindings that may not capture the regulatory requirements or the organizational performance

The most effective way to identify exfiltration of sensitive data by a malicious insider is to establish behavioral analytics monitoring. Behavioral analytics is the process of analyzing the patterns and anomalies in user behavior to detect and prevent insider threats. Behavioral analytics can help identify unusual or suspicious activities, such as accessing sensitive data at odd hours, transferring large amounts of data to external devices or locations, or using unauthorized applications or protocols. Behavioral analytics can also help correlate data from multiple sources, such as network logs, user profiles, and access rights, to provide a holistic view of user activity and risk.

Data loss prevention (DLP) software is a tool that can help prevent exfiltration of sensitive data by a malicious insider, but it is not the most effective way to identify it. DLP software can block or alert on unauthorized data transfers based on predefined rules and policies, but it may not be able to detect sophisticated or stealthy exfiltration techniques, such as encryption, steganography, or data obfuscation.

Reviewing perimeter firewall logs is a way to identify exfiltration of sensitive data by a malicious insider, but it is not the most effective way. Perimeter firewall logs can show the traffic volume and destination of data transfers, but they may not be able to show the content or context of the data. Perimeter firewall logs may also be overwhelmed by the amount of normal traffic and miss the signals of malicious exfiltration.

Providing ongoing information security awareness training is a way to reduce the risk of exfiltration of sensitive data by a malicious insider, but it is not a way to identify it. Information security awareness training can help educate users on the importance of protecting sensitive data and the consequences of violating policies and regulations, but it may not deter or detect those who are intentionally or maliciously exfiltrating data.

The finding that should be of greatest concern to an IS auditor assessing the risk associated with end-user computing (EUC) in an organization is the lack of defined criteria for EUC applications. EUC applications are applications that are developed and maintained by end-users, rather than by IT professionals, to support their business functions and processes. Examples of EUC applications include spreadsheets, databases, reports, and scripts. The lack of defined criteria for EUC applications means that the organization does not have clear and consistent standards or guidelines to identify, classify, and manage EUC applications. This can lead to various risks, such as:

Inaccurate or unreliable data and results from EUC applications that are not validated, verified, or tested

Unauthorized or inappropriate access or use of EUC applications that are not secured, controlled, or monitored

Inconsistent or incompatible data and results from EUC applications that are not integrated, documented, or updated

Loss or corruption of data and results from EUC applications that are not backed up, recovered, or archived

Therefore, the IS auditor should be most concerned about the lack of defined criteria for EUC applications, as it can affect the quality, integrity, and availability of the EUC applications and the data they produce.

Insufficient processes to track ownership of each EUC application is a finding that should be of concern to an IS auditor assessing the risk associated with EUC in an organization, but it is not the greatest concern. The ownership of an EUC application refers to the person or group who is responsible for creating, maintaining, and using the EUC application. Insufficient processes to track ownership of each EUC application means that the organization does not have adequate mechanisms orrecords to identify and communicate who owns each EUC application. This can lead to risks, such as:

Lack of accountability or ownership for the quality and accuracy of the EUC application and its data

Lack of support or maintenance for the EUC application when the owner leaves or changes roles

Lack of awareness or training for the users of the EUC application on its purpose and functionality

However, these risks are less severe than those caused by the lack of defined criteria for EUC applications.

Insufficient processes to test for version control is a finding that should be of concern to an IS auditor assessing the risk associated with EUC in an organization, but it is not the greatest concern. Version control is a process that tracks and manages the changes made to an EUC application over time. Insufficient processes to test for version control means that the organization does not have adequate procedures or tools to ensure that the changes made to an EUC application are authorized, documented, and tested. This can lead to risks, such as:

Errors or inconsistencies in the data and results from different versions of the EUC application

Conflicts or confusion among the users of the EUC application on which version is current or correct

Loss or overwrite of data and results from previous versions of the EUC application

However, these risks are less severe than those caused by the lack of defined criteria for EUC applications.

Lack of awareness training for EUC users is a finding that should be of concern to an IS auditor assessing the risk associated with EUC in an organization, but it is not the greatest concern. Awareness training for EUC users is a process that educates and informs the users of the EUC applications on their roles, responsibilities, and risks. Lack of awareness training for EUC users means that the organization does not have adequate programs or materials to raise the knowledge and skills of the users on how to use and manage the EUC applications effectively and securely. This can lead to risks, such as:

Misuse or abuse of the EUC applications by users who are not aware of their impact or implications

Non-compliance or violation of policies or regulations by users who are not aware of their requirements or expectations

Dissatisfaction or frustration among users who are not aware of their benefits or limitations

However, these risks are less severe than those caused by the lack of defined criteria for EUC applications.

 The planning phase is the stage of the internal audit process where contact is established with the individuals responsible for the business processes in scope for review. The planning phase involves defining the objectives, scope, and criteria of the audit, as well as identifying the key risks and controls related to the audited area. The planning phase also involves communicating with the auditee to obtain relevant information, documents, and data, as well as to schedule interviews, walkthroughs, and meetings. The planning phase aims to ensure that the audit team has a clear understanding of the audited area and its context, and that the audit plan is aligned with the expectations and needs of the auditee and other stakeholders.

The execution phase is the stage of the internal audit process where the audit team performs the audit procedures according to the audit plan. The execution phase involves testing the design and operating effectiveness of the controls, collecting and analyzing evidence, documenting the audit work and results, and identifying any issues or findings. The execution phase aims to provide sufficient and appropriate evidence to support the audit conclusions and recommendations.

The follow-up phase is the stage of the internal audit process where the audit team monitors and verifies the implementation of the corrective actions agreed upon by the auditee in response to the audit findings. The follow-up phase involves reviewing the evidence provided by the auditee, conducting additional tests or interviews if necessary, and evaluating whether the corrective actions have adequately addressed the root causes of the findings. The follow-up phase aims to ensure that the auditee has taken timely and effective actions to improve its processes and controls.

The selection phase is not a standard stage of the internal audit process, but it may refer to the process of selecting which areas or functions to audit based on a risk assessment or an annual audit plan. The selection phase involves evaluating the inherent and residual risks of each potential auditable area, considering the impact, likelihood, and frequency of those risks, as well as other factors such as regulatory requirements, stakeholder expectations, previous audit results, and available resources. The selection phase aims to prioritize and allocate the audit resources to those areas that present the highest risks or opportunities for improvement.

Therefore, option A is the correct answer.

 A stateful firewall provides the greatest assurance that outgoing Internet traffic is controlled, as it monitors and filters packets based on their source, destination and connection state. A stateful firewall can prevent unauthorized or malicious traffic from leaving the network, as well as block incoming traffic that does not match an established connection. An intrusion detection system (IDS) can detect and alert on suspicious or anomalous traffic, but it does not block or control it. A security information and event management (SIEM) system can collect and analyze logs and events from various sources, but it does not directly control traffic. A load balancer can distribute traffic among multiple servers, but it does not filter or monitor it. References: CISA ReviewManual (Digital Version), Chapter 6, Section 6.2

The finding that should be of most concern to an IS auditor when evaluating information security governance within an organization is that the data center manager has final sign-off on security projects. This indicates a lack of segregation of duties and a potential conflict of interest between the operational and security roles. The data center manager may have access to sensitive information or systems that should be protected by security controls, or may influence or override security decisions that are not in the best interest of the organization. This finding also suggests that there is no clear accountability or authority for information security governance at a higher level, such as senior management or board of directors. The other findings are not as concerning as this one, although they may indicate some areas for improvement or monitoring. References:

The auditor should be most concerned about the information security policy not being approved by the policy owner. This is because the policy owner is the person who has the authority and accountability for ensuring that the policy is implemented and enforced. Without the policy owner’s approval, the policy may not reflect the organization’s objectives, risks, and compliance requirements. The policy owner is usually a senior executive or a board member who has a stake in the information security governance. The other options are less critical than the policy owner’s approval, although they may also indicate some weaknesses in the policy development and maintenance process. References:

The greatest risk if two users have concurrent access to the same database record is data integrity. Data integrity is the property that ensures that the data is accurate, complete, consistent, and valid throughout its lifecycle. If two users have concurrent access to the same database record, they may modify or delete the data in a conflicting or inconsistent manner, resulting in data corruption, loss, or duplication. This can affect the reliability and quality of the data, and cause errors or anomalies in the database operations and functions. The IS auditor should verify that the database has adequate controls to prevent or resolve concurrent access issues, such as locking mechanisms, transaction isolation levels, concurrency control protocols, or timestamping methods. References: CISA Review Manual (Digital Version)1, Chapter 5, Section 5.2.7

Whenclassifying information, it is most important to align the classification to business risk, because it ensures that the information is protected according to its value andimpact to the organization34. Business risk considers factors such as legal, regulatory, contractual, operational, reputational, and financial implications of information disclosure or compromise34. Aligning information classification to business risk also helps to prioritize and allocate resources for information security measures. Security policy, data retention requirements, and industry standards are important considerations for information classification, but not as important as business risk. References: 3: CISA Review Manual(Digital Version), Chapter 5, Section 5.4.2 4: CISA Online Review Course, Module 5, Lesson 4

 The most useful analytical method when trying to identify groups with similar behavior or characteristics in a large population is classification. Classification is a technique that assigns data points to predefined categories or classes based on their features or attributes. Classification can help to discover patterns, trends, and relationships among the data and reveal the similarities or differences among the groups. Classification can also help to support decision making, prediction, or recommendation based on the data analysis. References:

The auditor’s next action after finding that there is an informal unwritten set of standards in the IS department is to document and test compliance with the informal standards. This is because the auditor’s role is to evaluate the adequacy and effectiveness of the existing controls, regardless of whether they are formal or informal, written or unwritten. The auditor should also assess the risks and implications of having informal standards, such as lack of consistency, accountability, or traceability. The auditor should not make recommendations, postpone the audit, or finalize the audit without performing the audit procedures. References:

Issuing authentication tokens is the most reliable method of preventing unauthorized logon, as it provides a strong form of authentication that requires users to present something they have (the token) and something they know (the personal identification number or PIN) to access the system. Authentication tokens are physical devices that generate a one-time password or code that changes periodically and is synchronized with the authentication server. This makes it difficult for attackers to steal or guess the credentials of legitimate users. Reinforcing current security policies, limiting after-hours usage and installing an automatic password generator are not as reliable as issuing authentication tokens, as they do not provide a strong form of authentication and may still be vulnerable to unauthorized logon attempts. References:

 Implementing an email containerization solution on personal devices is the best recommendation for an IS auditor, because it allows the organization to separate and secure the email data from the rest of the device data. Email containerization creates a virtual environment that encrypts andisolates the email data, preventing unauthorized access, leakage, or loss of sensitive information12. Requiring passwords or antivirus protection on personal devices may not be sufficient or enforceable, while prohibiting employees from storing companyemail onpersonal devices may not be feasible or practical. References: 1: CISA Review Manual (DigitalVersion), Chapter 5, Section 5.4.3 2: CISA Online Review Course, Module 5, Lesson 4

 The type of control that is in place when an organization has established hiring policies and procedures designed specifically to ensure network administrators are well qualified is directive. Directive controls are those that guide or direct the actions of individuals or groups to achieve a desired outcome. Directive controls can also help to prevent or reduce the occurrence of undesirable events. Hiring policies and procedures are examples of directive controls that aim to ensure that only qualified and competent personnel are employed to perform IT-related tasks. References:

The most important thing to consider before including an audit of IT capacity management in the program is whether the system’s performance poses a significant risk to the organization. IT capacity management is a process that ensures that IT resources are sufficient to meet current and future business needs, and that they are optimized for cost and performance. A poor IT capacity management can result in system slowdowns, outages, failures, or breaches, which can affect the availability, reliability, security, and efficiency of IT services and business processes. Therefore, before conducting an audit of IT capacity management, the auditor should assess the potential impact and likelihood of these risks on the organization’s objectives, reputation, compliance, and customer satisfaction.

Whether system delays result in more frequent use of manual processing (option A) is not the most important thing to consider before including an audit of IT capacity management in the program, as it is only one possible consequence of poor IT capacity management. Manual processing can introduce errors, delays, inefficiencies, and inconsistencies in the data and reports, which can affect the quality and accuracy of financial information. However, manual processing is not the only or the worst outcome of poor IT capacity management; there may be other more severe or frequent risks that need to be considered.

Whether stakeholders are committed to assisting with the audit (option C) is also not the most important thing to consider before including an audit of IT capacity management in the program, as it is a factor that affects the feasibility and effectiveness of the audit, not the necessity or priority of it. Stakeholder commitment is important for ensuring that the auditor has access to relevant information, documents, data, and personnel, as well as for facilitating communication, collaboration, and feedback during the audit process. However, stakeholder commitment is not a sufficient reason to conduct an audit of IT capacity management; there must be a clear risk-based rationale for selecting this area for audit.

Whether internal auditors have the required skills to perform the audit (option D) is also not the most important thing to consider before including an audit of IT capacity management in the program, as it is a factor that affects the quality and credibility of the audit, not the urgency or importance of it. Internal auditors should have the appropriate knowledge, skills, and experience to perform an audit of IT capacity management, which may include technical, business, analytical, and communication skills. However, internal auditors can also acquire or supplement these skills through training, coaching, consulting, or outsourcing. Therefore, internal auditors’ skills are not a decisive factor for choosing this area for audit.

Therefore, option B is the correct answer.

 The auditor should be most concerned with the impact AI will have on enterprise architecture (EA) when reviewing a project to replace multiple manual data entry systems with an AI system. EA is a comprehensive framework that defines the structure, components, relationships, and principles of an organization’s IT environment. EA can help to align the IT strategy with the business strategy and ensure the coherence, consistency, and integration of the IT systems and services. Replacing manual data entry systems with an AI system may have significant implications for the EA, such aschanging the business processes, data flows, security requirements, performance standards, or governance models. The auditor should assess whether the project has considered the impact of AI on EA and whether the EA has been updated accordingly. References:

The best assurance of data integrity after file transfers is hash values. Hash values are unique strings that are generated by applying a mathematical function to the data. Hash values can be used to verify that the data has not been altered or corrupted during the transfer, as any change in the data would result in a different hash value. By comparing the hash values of the source and destination files, one can confirm that the data is identical and intact.

The other options are not as effective as hash values for ensuring data integrity after file transfers. Check digits are digits added to a number to detect errors in data entry or transmission, but they are not reliable for detecting intentional or complex modifications of the data. Monetary unit sampling is a statistical sampling technique used for auditing financial statements, but it is not applicable for verifying data integrity after file transfers. Reasonableness check is a validation method that checks whether the data falls within an expected range or format, but it does not guarantee that the data is accurate or consistent with the source.

 A distributed security administration system is a system that allows different administrators to manage the security of different parts of the network or organization. This can provide more flexibility, scalability, and efficiency than a centralized system, where one administrator is responsible for the entire security. However, a distributed security administration system also presents some potential challenges and risks, such as:

Inconsistency and conflict among different security policies and standards

Lack of coordination and communication among different administrators

Difficulty in monitoring and auditing the overall security status and performance

Increased complexity and cost of security management and maintenance

Therefore, the greatest potential concern for implementing a distributed security administration system is that the security procedures may be inadequate to support the change. Security procedures are the rules and guidelines that define how security is implemented and enforced in an organization. They include policies, standards, processes, roles, responsibilities, controls, and metrics. Security procedures should be aligned with the business objectives, risks, and requirements of the organization, as well as the best practices and regulations in the industry. Security procedures should also be reviewed and updated regularly to reflect the changes in the environment, technology, and threats.

If the security procedures are not adequate to support the change from a centralized to a distributed security administration system, the organization may face increased security risks, such as unauthorized access, data breaches, compliance violations, reputation damage, and financial losses. Therefore, it is essential to ensure that the security procedures are revised and adapted to suit the new system, and that they are communicated and enforced effectively across the organization.

The greatest concern to an IS auditor conducting an audit of an organization that recently experienced a ransomware attack is that backups were only performed within the local network. This means that the backups could have been encrypted or deleted by the ransomware, making it impossible to restore the data and systems without paying the ransom or losing the data. Backups are a critical part of the recovery process from a ransomware attack, and they should be performed frequently, securely, and off-site or in the cloud to ensure their availability and integrity.

The other options are not as concerning as option C, although they may also indicate some security weaknesses. Antivirus software was unable to prevent the attack even though it was properly updated, but this is not surprising given that ransomware variants are constantly evolving and antivirus software may not be able to detect them all. The most recent security patches were not tested prior to implementation, but this is a trade-off between security and availability that may be justified depending on the severity and urgency of the patches. Employees were not trained on cybersecurity policies and procedures, but this is a preventive measure that may not have prevented the attack if it was initiated by other means such as phishing or exploiting vulnerabilities.

 An IS auditor is analyzing a sample of accounts payable transactions for a specific vendor and identifies one transaction with a value five times as high as the average transaction. The next step that the auditor should do is to request an explanation of the variance from the auditee. This is because the variance may indicate an error, fraud, or an unusual but legitimate transaction that requires further investigation. The auditor should not report the variance immediately to the audit committee without verifying its cause and significance. The auditor should not increase the sample size to 100% of the population without considering the cost-benefit analysis and the sampling methodology. The auditor should not exclude the transaction from the sample population without justification, as itmay affect the validity and reliability of the audit results. References: CISA Review Manual (Digital Version), [ISACA Auditing Standards]

 The best method to reduce the risk associated with the transition to a new system using technologies that are not compatible with the old system is parallel changeover. Parallel changeover is a method of system conversion that involves running both the old and the new systems simultaneously for a period of time, until the new system is verified to be working correctly and completely. Parallel changeover can help reduce the risk of data loss, errors, or disruptions that may occur due to the incompatibility of the technologies, as well as provide a backup option in case of failure or malfunction of the new system. Parallel changeover can also help users compare and validate the results of both systems, and facilitate their training and adaptation to the new system.

Modular changeover is a method of system conversion that involves replacing one module or component of the old system with a corresponding module or component of the new system at a time, until the entire system is replaced. Modular changeover can help reduce the complexity and scope of the conversion, as well as minimize the impact on the users and operations. However, modular changeover may not be feasible or effective when the technologies of the old and new systems are not compatible, as it may create integration or interoperability issues among the modules.

Phased operation is a method of system conversion that involves implementing the new system in stages or increments, each with a subset of functions or features, until the entire system is operational. Phased operation can help reduce the risk and cost of implementing a large and complex system, as well as allow for testing and feedback at each stage. However, phased operation may not be suitable or efficient when the technologies of the old and new systems are not compatible, as it may require extensive modifications or adaptations to enable partial functionality.

Pilot operation is a method of system conversion that involves implementing the new system in a limited or controlled environment, such as a department or a location, before rolling it out to the entire organization. Pilot operation can help test and evaluate the performance and usability of the new system, as well as identify and resolve any issues or problems before full-scale implementation. However, pilot operation may not be relevant or reliable when the technologies of the old and new systems are not compatible, as it may not reflect the actual conditions or challenges of operating both systems concurrently.

The first step in managing the impact of a recently discovered zero-day attack is to identify vulnerable assets. A zero-day attack is a cyberattack that exploits a previously unknown or unpatched vulnerability in a software or system, before the vendor or developer has had time to fix it. Identifying vulnerable assets is crucial for managing the impact of a zero-day attack, because it helps to determine the scope and severity of the attack, prioritize the protection and mitigation measures, and isolate or quarantine the affected assets from further damage or compromise. The other options are not the first steps in managing the impact of a zero-day attack, because they either require more informationabout the vulnerable assets, or they are part of the subsequentsteps of assessing, responding, or recovering from the attack. References: CISA Review Manual (Digital Version)1, Chapter 5, Section 5.2.4

A demilitarized zone (DMZ) is a network segment that is separated from the internal network and the external network, such as the internet, by firewalls or other security devices. A DMZ provides an extra layer of security for the organization’s internal network by isolating the servers and services that need to be accessible to external users, such as a file server, from the rest of the network. A DMZ also prevents external users from accessing the internal network directly, as they have to go through two firewalls to reach it. Therefore, setting up a DMZ is an IS auditor’s best recommendation to protect anorganization from attacks when its file server needs to be accessible to external users12.

The other possible options are:

Enforce a secure tunnel connection: This means that the organization requires external users to establish a secure and encrypted connection, such as a virtual private network (VPN), to access its file server. This can provide some level of security and privacy for the data transmission, but it does not protect the file server or the internal network from attacks if the connection is compromised or if the external users are malicious. Therefore, enforcing asecuretunnel connection is not an IS auditor’s best recommendation to protect an organization from attacks when its file server needs to be accessible to external users3.

Enhance internal firewalls: This means that the organization improves the security and performance of its internal firewalls, which are devices that filter and control the network traffic between different segments of the network. This can provide some level of protection for the internal network from unauthorized or malicious access, but it does not protect the file server or the external network from attacks if the file server is exposed to the internet or if the external network is compromised. Therefore, enhancing internal firewalls is not an IS auditor’s best recommendation to protect an organization from attacks when its file server needs to be accessible to external users4.

Implement a secure protocol: This means that the organization uses a secure and standardized protocol, such as Secure File Transfer Protocol (SFTP) or Secure Shell (SSH), to transfer files between its file server and external users. This can provide some level of security and integrity for the data transmission, but it does not protect the file server or the internal network from attacks if the protocol is exploited or if the external users are malicious. Therefore, implementing a secure protocol is not an IS auditor’s best recommendation to protect an organization from attacks when its file server needs to be accessible to external users5. References: 1: What Is a DMZ Network and Why Would You Use It? | Fortinet 2: Demilitarised zone (DMZ) | Cyber.gov.au 3: What Is VPN Tunneling? | Fortinet 4: Firewall - Wikipedia 5: Secure Shell - Wikipedia

The answer D is correct because the number of reopened tickets is the best indicator for measuring the performance of IT help desk function. Reopened tickets are tickets that have been marked as resolved by the help desk agents, but the customers are not satisfied with the resolution and reopen them for further assistance. Reopened tickets reflect the quality and effectiveness of the help deskservice, as well as the customer satisfaction level. A high number of reopened tickets indicates that the help desk agents are not resolving the issues properly, or that they are not communicating well with the customers. This can lead to customer frustration, dissatisfaction, and churn. Therefore, minimizing the number of reopened tickets is a key goal for any help desk function.

The other options are not as good as option D. Percentage of problems raised from incidents (option A) is a metric that shows how many incidents are escalated to problems, which are more complex and require root cause analysis and long-term solutions. This metric reflects the complexity and severity of the issues faced by the customers, but it does not directly measure the performance of the help desk function. Mean time to categorize tickets (option B) is a metric that shows how long it takes for the help desk agents to assign a category to each ticket, such as technical, billing, or feedback. This metric reflects the efficiency and accuracy of the help desk agents, but it does not measure the quality or effectiveness of the resolution. Number of incidents reported (option C) is a metric that shows how many issues are reported by the customers to the help desk function. This metric reflects the demand and workload of the help desk function, but it does not measure how well the issues are resolved or how satisfied the customers are.

 Information security governance is the subset of enterprise governance that provides strategic direction, ensures that objectives are achieved, manages risk appropriately, uses organizational resources responsibly, and monitors the success or failure of the enterprise security program. Information security governance is essential for ensuring that an organization’s information assets are protected from internal and external threats, and that the organization complies with relevant laws and standards.

Demonstrated support from which of the following roles in an organization has the most influence over information security governance? The answer is C, the board of directors. The board of directors is the highest governing body of an organization, responsible for overseeing its strategic direction, performance, and accountability. The board of directors sets the tone at the top for information security governance by:

Establishing a clear vision, mission, and values for information security

Approving and reviewing information security policies and standards

Allocating sufficient resources and budget for information security

Appointing and empowering a chief information security officer (CISO) or equivalent role

Holding management accountable for information security performance and compliance

Communicating and promoting information security awareness and culture

The board of directors has the most influence over information security governance because it has the ultimate authority and responsibility for ensuring that information security is aligned with the organization’s business objectives, risks, and stakeholder expectations.

Attribute sampling is a method of audit sampling that is used to test the effectiveness of controls by measuring the rate of deviation from a prescribed procedure or attribute. Attribute sampling is suitable for testing compliance with the data center’s physical access log system, as the auditor can compare the identification document numbers and photos of the visitors with the records in the system and determine whether there are any discrepancies or errors. Attribute sampling can also provide an estimate of the deviation rate in the population and allow the auditor to draw a conclusion about the operating effectiveness of the control.

Variable sampling, on the other hand, is a method of audit sampling that is used to estimate the amount or value of a population by measuring a characteristic of interest, such as monetary value, quantity, or size. Variable sampling is not appropriate for testing compliance with the data center’s physical access log system, as the auditor is not interested in estimating the value of the population, but rather in testing whether the system is operating as intended.

Quota sampling and haphazard sampling are both examples of non-statistical sampling methods that do not use probability theory to select a sample. Quota sampling involves selecting a sample based on certain criteria or quotas, such as age, gender, or location. Haphazard sampling involves selecting a sample without any specific plan or method. Both methods are not suitable for testing compliance with the data center’s physical access log system, as they do not ensure that the sample is representative of the population and do not allow the auditor to measure the sampling risk or project the results to the population.

Therefore, attribute sampling is the most useful sampling method for an IS auditor conducting compliance testing for the effectiveness of the data center’s physical access log system.

A web-based CRM system that is directly accessed by customers via the Internet should be hosted in a secure and isolated environment to protect it from external threats and unauthorized access. A web-based CRM system should also be reliable, trusted, and backedup regularly1.

Hosting the system on an external third-party service provider’s servers (A) or a hybrid-cloud platform managed by a service provider (B) may not be a concern for the auditor if the service provider has adequate security measures and service level agreements in place. The auditor should verify the security controls and contractual terms of the service provider before trusting them with the CRM data23.

Hosting the system within a demilitarized zone (DMZ) of a corporate network © is a common practice to provide an extra layer of security to the CRM system from untrusted networks, such as the Internet. A DMZ is a perimeter network that isolates the CRM system from the internal network and filters the incoming traffic from the external network using a security gateway4567.

Hosting the system within an internal segment of a corporate network (D) is a concern for the auditor because it exposes the CRM system and the internal network to potential attacks from the Internet. The CRM system should not be directly accessible from the Internet without a DMZ or a firewall to protect it. This could compromise the confidentiality, integrity, and availability of the CRM data and the internal network78.

A recovery point objective (RPO) is the maximum acceptable amount of data loss after an unplanned data-loss incident, expressed as an amount of time. This is generally thought of as the point in time before the event at which data can be successfully recovered– that is, the time elapsed since the most recent reliable backup1. RPOs are important to consider when reviewing an organization’s defined data backup and restoration procedures, because they determine how frequently the organization needs to perform backups, and how much data it can afford to lose in case of a disaster. RPOs are usually defined based on the business impact and criticality of the data, as well as the compliance and regulatory requirements. For example, a financial institution may have a very low RPO (such as a few minutes or seconds) for its transactional data, while a research institute may have a higher RPO (such as a few hours or days) for its experimental data.

The other possible options are:

A. Business continuity plan (BCP): A BCP is a document that outlines how an organization will continue to operate or resume its critical functions and processes in the event of a disruption or disaster. A BCP includes various elements, such as risk assessment, business impact analysis, recovery strategies, roles and responsibilities, communication plan, and testing and maintenance. A BCP is related to an organization’s defined data backup and restoration procedures, but it is not the most important factor to consider when reviewing them. A BCP defines the recovery objectives and strategies for the entire organization, while the data backup and restoration procedures are more specific and technical in nature.

C. Mean time to restore (MTTR): MTTR is a metric that measures the average time it takes to restore a system or service after a failure or outage. MTTR is an indicator of the efficiency and effectiveness of an organization’s recovery process, as well as the availability and reliability of its systems or services. MTTR is related to an organization’s defined data backup and restoration procedures, but it is not the most important factor to consider when reviewing them. MTTR reflects the actual performance of the recovery process, while the data backup and restoration procedures define the expected steps and actions for the recovery process.

D. Mean time between failures (MTBF): MTBF is a metric that measures the average time between failures or outages of a system or service. MTBF is an indicator of the quality and durability of an organization’s systems or services, as well as their susceptibility to failures or outages. MTBF is related to an organization’s defined data backup and restoration procedures, but it is not the most important factor to consider when reviewing them. MTBF reflects the potential frequency of failures or outages, while the data backup and restoration procedures define the contingency plans for failures or outages.

 This is because privacy regulations are laws or rules that protect the personal information of individuals from unauthorized access, use, disclosure, or transfer by third parties. Payroll audit documentation may contain sensitive and confidential data, such as employee names, salaries, benefits, taxes, deductions, and bank accounts. If the audit management application is hosted by a third party in a different country, the organization may need to comply with the privacy regulations of both its own country and the host country, as well as any international or regional agreements or frameworks that apply. Privacy regulations may impose various requirements and obligations on the organization, such as obtaining consent from the data subjects, implementing appropriate security measures, notifying data breaches, and ensuring data quality and accuracy. Privacy regulations may also grant various rights to the data subjects, such as accessing, correcting, deleting, or transferring their data. Failing to comply with privacy regulations may expose the organization to significant risks and consequences, such as legal actions, fines, sanctions, reputational damage, or loss of trust.

Some examples of privacy regulations affecting the organization are:

The General Data Protection Regulation (GDPR), which is a comprehensive and strict privacy regulation that applies to anyorganization that processes personal data of individuals in the European Union (EU) or offers goods or services to them, regardless ofwhere the organization or the data is located1.

The California Consumer Privacy Act (CCPA), which is a broad and influential privacy regulation that applies to any organization that collectspersonal information of California residentsand meets certain thresholds of revenue, data volume, or data sharing2.

The Health Insurance Portability and Accountability Act (HIPAA), which is a sector-specific privacy regulation that applies to any organization that handles protected health information(PHI) of individuals in the United States, such as health care providers, health plans, or health care clearinghouses3.

Therefore, before using an audit management application hosted by a third party in a different country, the internal audit team should conduct a thorough assessment of the privacy regulations affecting the organization and ensure that they have adequate policies, procedures, and controls in place to comply with them.

The concept of materiality is most important for an IS auditor to apply when planning an audit engagement, because it helps the auditor to determine the scope, objectives, procedures and resources of the audit. Materiality is the degree to which an omission or misstatement of information could affect the users’ decisions or the achievement of the audit objectives. By applying the concept of materiality, the auditor can focus on the most significant and relevant areas of the audit and avoid wasting time and effort on trivial or immaterial matters. The other options are not as important as planning an audit engagement, because they are either based on or affected by the materiality assessment done during the planning phase. References:

ISACA, CISA Review Manual, 27th Edition, chapter 1, section 1.31

ISACA, IT Audit and Assurance Standards, Guidelines and Tools and Techniques forIS Audit and Assurance Professionals, section 12022

The greatest concern to an IS auditor who is assessing an organization’s configuration and release management process is that changes and change approvals are not documented. This is because documentation is essential for ensuring the traceability, accountability, and quality of the changes made to the configuration items (CIs) and the releases deployed to the production environment. Without documentation, it would be difficult to verify the authenticity, validity, and authorization of the changes, as well as to identify and resolve any issues or incidents that may arise from the changes. Documentation also helps to maintain compliance with internal and external standards and regulations, as well as to facilitate audits and reviews.

The other options are not as concerning as option B, although they may also indicate some weaknesses in the configuration and release management process. The organization does not use an industry-recognized methodology, but this does not necessarily mean that their process is ineffective or inefficient. The organization may have developed their own methodology that suits their specific needs and context. However, using an industry-recognized methodology could help them adopt best practices and improve their process maturity. All changes require middle and senior management approval, but this may not be a problem if the organization has a clear and streamlined approval process that does not cause delays or bottlenecks in the change implementation. However, requiring too many approvals could also introduce unnecessary complexity and bureaucracy in the process. There is no centralized configuration management database (CMDB), but this does not mean that the organization does not have a way of managing their CIs and their relationships. The organization may use other tools or methods to store and access their configuration data, such as spreadsheets, documents, or repositories. However, having a centralized CMDB could help them improve their visibility, accuracy, and consistency of their configuration data.

The best way for the auditor to address this issue is to verify management has approved a policy exception to accept the risk. A policy exception is a formal authorization that allows a deviation from the established policy requirements for a specific situation or period of time. A policy exception should be based on a risk assessment that evaluates the impact and likelihood of the potential threats and vulnerabilities, as well as the cost and benefit of the alternative controls. A policy exception should also be documented, approved, and monitored by management.

Recommending the application be patched to meet requirements is not the best way for the auditor to address this issue. Patching the application may not be feasible, cost-effective, or timely, given that the application will be decommissioned in three months. Patching the application may also introduce new risks or errors that could affect the functionality or performance of the application.

Informing the IT director of the policy noncompliance is not the best way for the auditor to address this issue. Informing the IT director of the policy noncompliance may not resolve the issue or mitigate the risk, especially if the IT director is already aware of the situation and has decided to accept it. Informing the IT director of the policy noncompliance may also create unnecessary conflict or tension between the auditor and the auditee.

Taking no action since the application will be decommissioned in three months is not the best way for the auditor to address this issue. Taking no action may expose the organization to significant risks or consequences, such as data breaches, regulatory fines, or reputational damage, if the application is compromised or exploited by malicious actors. Taking no action may also violate the auditor’s professional standards and responsibilities, such as due care, objectivity, and reporting.

The best way to sanitize a hard disk for reuse to ensure the organization’s information cannot be accessed is data wiping. Data wiping is a process that overwrites the data on the hard disk with random or meaningless patterns, making it unrecoverable by any software or hardware methods. Data wiping can provide a high level of security and assurance that the organization’s information is permanently erased from the hard disk, and that it cannot be accessed by unauthorized parties or malicious actors.

Re-partitioning is not a way to sanitize a hard disk for reuse, but rather a way to organize the hard disk into different logical sections or volumes. Re-partitioning does not erase the data on the hard disk, but only changes the structure and allocation of the disk space. Re-partitioning may make the data inaccessible to the operating system, but not to other tools or methods that can scan or recover the data from the disk sectors.

Degaussing is a way to sanitize a hard disk for reuse, but only for magnetic hard disks, not solid state drives (SSDs). Degaussing is a process that exposes the hard disk to a strong magnetic field, which disrupts and destroys the magnetic alignment of the data on the disk platters. Degaussing can effectively erase the data on magnetic hard disks, but it can also damage or render unusable the electronic components of the hard disk, such as the read/write heads or circuit boards. Degaussing also does not work on SSDs, which store data using flash memory cells, not magnetic media.

Formatting is not a way to sanitize a hard disk for reuse, but rather a way to prepare the hard disk for use by an operating system. Formatting is a process that creates a file system on the hard disk, which defines how the data is stored and accessed on the disk. Formatting does not erase the dataon the hard disk, but only deletes the file system metadata and marks the disk space as available for new data. Formatting may make the data invisible to the operating system, but not to other tools or methods that can restore or recover the data from the disk sectors.

 The best recommendation for an organization that does not have a process to identify and correct records that do not get transferred to the receiving system is to implement software to perform automatic reconciliations of data between systems. This will ensure that the data integrity and completeness are maintained and that any errors or discrepancies are detected and resolved in a timely manner. Enabling encryption, decryption, and electronic signing of data files may enhance the data security and authenticity, but not the data accuracy or consistency. Having coders perform manual reconciliation of data between systems may be prone to human errors and inefficiencies. Automating the transfer of data between systems as much as feasible may reduce the chances of data loss or corruption, but not eliminate them completely. References: ISAudit and Assurance Standards, section “Standard 1202: Risk Assessment in Planning”

 An organization is shifting to a remote workforce. In preparation, the IT department is performing stress and capacity testing of remote access infrastructure and systems. This type of control is being implemented to direct or guide actions to achieve a desired outcome. Therefore, it is a directive control. Directive controls are proactive controls that seek to prevent undesirable events from occurring. They include policies, standards, procedures, guidelines, training, and testing. Detective controls are reactive controls that seek to identify undesirable events that have already occurred. They include monitoring, logging, auditing, and reporting. Preventive controls are proactive controls that seek to avoid undesirable events from occurring. They include authentication, encryption, firewalls, and antivirus software. Compensating controls are alternative controls that provide a similar level of protection as the primary controls when the primary controls are not feasible or cost-effective. They include segregation of duties, manual reviews, and backup systems. References: CISA Review Manual (Digital Version), [ISACA Glossary of Terms]

The answer D is correct because the greatest concern for an IS auditor with the situation of business owners being removed from the project initiation phase is that the requirements may be incomplete. The project initiation phase is the first step in starting a new project, where the project’s purpose, scope, objectives, and deliverables are defined and documented. The project initiation phase also involves identifying and engaging the key stakeholders who have an interest or influence in the project, such as sponsors, customers, users, or business owners.

Business owners are the individuals or entities who have the authority and responsibility to define the business needs and expectations for the project. They are also the primary beneficiaries of the project outcomes and benefits. Business owners play a crucial role in the project initiation phase, as they provide valuable input and feedback on the requirements and specifications of the project. Requirements are the statements that describe what the project should accomplish or deliver to meet the business needs and expectations. Requirements are essential for guiding the project planning, execution, monitoring, and closure phases.

If business owners are removed from the project initiation phase, it can result in incomplete or inaccurate requirements, which can have negative impacts on the project’s quality, scope, time, cost, and risk. Some of the possible consequences of incomplete requirements are:

Misalignment: The project may not align with the business strategy, vision, or goals, which can reduce its value or relevance.

Confusion: The project team may not have a clear understanding of what the project should achieve or deliver, which can affect their performance or productivity.

Rework: The project may need to undergo frequent changes or revisions to accommodate new or modified requirements, which can increase the time and cost of the project.

Dissatisfaction: The project may not meet the expectations or satisfaction of the business owners or other stakeholders, which can affect their acceptance or support of the project.

Failure: The project may not deliver the expected outcomes or benefits, which can affect its success or viability.

Therefore, an IS auditor should be concerned about the involvement and participation of business owners in the project initiation phase, as it affects the completeness and quality of requirements. An IS auditor should review the policies and procedures for stakeholder identification and engagement, verify that the business owners have adequate knowledge and skills to define their requirements, and test that the requirements are well-defined, documented, approved, and communicated.

An IT balanced scorecard (BSC) is a performance metric that is used to identify, improve, and control the various functions and outcomes of an IT department or organization. An IT BSC is based on the concept of the balanced scorecard, which was introduced by Robert Kaplan and David Norton in 1992 as a strategic management system that translates the vision and strategy of an organization into measurable objectives and actions. An IT BSC adapts the balanced scorecard framework to the specific needs and goals of the IT function, aligning it with the business strategy and value proposition.

An IT BSC typically consists of four perspectives that help managers plan, implement, and evaluate the IT performance: customer, internal process, learning and growth, and financial. Each perspective defines a set of objectives, measures, targets, and initiatives that reflect the IT contribution to the organization’s success. For example, the customer perspective may measure the satisfaction and retention of internal and external customers who use IT services or products; the internal process perspective may measure the efficiency and effectiveness of IT processes such as development, delivery, support, or security; the learning and growth perspective may measure the skills, knowledge, innovation, and culture of the IT staff; and the financial perspective may measure the costs, benefits, and return on investment of IT projects or assets.

An IT BSC provides a new IS auditor with the most useful information to evaluate overall IT performance because it:

Provides a comprehensive and balanced view of the IT function from multiple angles and stakeholders

Links the IT objectives and activities to the business strategy and value creation

Enables a clear communication and alignment of expectations and priorities among IT managers, staff, customers, and other stakeholders

Facilitates a continuous monitoring and improvement of IT performance based on data-driven feedback and analysis

Supports a holistic and integrated approach to IT governance, risk management, and compliance

Therefore, an IT BSC is a valuable tool for a new IS auditor to assess how well the IT function is fulfilling its mission and delivering value to the organization.

The greatest concern for an IS auditor when auditing an organization’s IT strategy development process is that information security was not included as a key objective in the IT strategic plan. Information security is a vital component of IT strategy, as it ensures the confidentiality, integrity and availability of information assets, and supports the business objectives and regulatory compliance. The other options are not as significant as the lack of information security in the IT strategic plan. References: CISA Review Manual (Digital Version), Chapter 1, Section 1.31

Stress testing is a type of performance testing that evaluates how a system behaves under extreme load conditions, such as high user traffic, large data volumes, or limited resources. It is useful for identifying potential bottlenecks, errors, or failures that may affect the system’s functionality or availability. Stress testing during the quality assurance (QA) phase would have identified the concern of users complaining that a newly released ERP system is functioning too slowly. The other options are not as relevant for this concern, as they relate to different aspects of testing, such as regression testing (verifying that existing functionality is not affected by new changes), interface testing (verifying that the system interacts correctly with other systems or components), or integration testing (verifying that the system works as a whole after combining different modules or units). References: CISA Review Manual (Digital Version), Domain 5: Protection of Information Assets, Section 5.4 Testing Techniques1

The main purpose of an IDS is to detect and report malicious or suspicious activity on a network or a host. If an IDS fails to identify actual attacks, it means that the IDS is not functioning properly or effectively, and it exposes the organization to serious security risks and potential damage. This is the most concerning scenario for an IS auditor, as it indicates a major deficiency in the IDS performance and configuration.

 Recounting the transaction records to ensure no records are missing provides assurance that the best transactions were recovered successfully from a snapshot copy. This is because recounting the transaction records can verify that the number of records in the restored database matches the number of records in the snapshot copy, which represents the state of the database before the deletion occurred. Recounting the transaction records can also detect any data corruption or inconsistency that may have occurred during the restore process1.

Reviewing transaction recovery logs to ensure no errors were recorded is not the best answer, because transaction recovery logs may not capture all the details or issues that may affect the data quality or integrity. Transaction recovery logs are mainly used to monitor and troubleshoot the restore process, but they may not reflect the actual content or accuracy of the restored data2.

Rerunning the process on a backup machine to verify the results are the same is not the best answer, because rerunning the process may introduce additional errors or inconsistencies that may affect the data quality or integrity. Rerunning theprocess may also consume more time and resources than necessary, and it may not guarantee that the results are identical to the original data3.

Comparing transaction values against external statements to verify accuracy is not the best answer, because external statements may not be available or reliable for all transactions. External statements are documents or reports that provide information about transactions from a third-party source, such as a bank, a vendor, or a customer. However, external statements may not cover all transactions, or they may have differentformats, standards, or timeliness than the internal data

The quality assurance (QA) phase is the phase where the IS auditor should first examine requirements from an in-house SDLC project that has not met user specifications. This is because the QA phase is the phase where the system is tested and verified against the user specifications and the design specifications to ensure that it meets the functional and non-functional requirements, as well as the quality standards and expectations. The QA phase involves various testing activities, such as unit testing, integration testing, system testing, acceptance testing, performance testing, security testing, etc., to identify and resolve any defects, errors, or deviations from the specifications12.

The configuration phase is not the phase where the IS auditor should first examine requirements from an in-house SDLC project that has not met user specifications. The configuration phase is the phase where the system is installed and configured on the target environment, such as hardware, software, network, etc., to prepare it for deployment and operation. The configuration phase may involve activities such as installation, customization, migration, integration, etc., to ensure that the system is compatible and interoperable with the existinginfrastructure and systems34.

The user training phase is not the phase where the IS auditor should first examine requirements from an in-house SDLC project that has not met user specifications. The user training phase is the phase where the end-users are trained and educated on how to use the system effectively and efficiently. The user training phase may involve activities such as developing training materials, conducting training sessions, providing feedback and support, etc., to ensure that the users are familiar and comfortable with the system features and functions56.

The development phase is not the phase where the IS auditor should first examine requirements from an in-house SDLC project that has not met user specifications. The development phase is the phase where the system is coded and built based on the design specifications and the user specifications. The development phase may involve activities such as programming, debugging, documenting, etc., to create a working prototype or a final product of the system

The best way to determine whether unauthorized changes have been made to production programs is to use source code comparison software to compare the current version of the programs with the previous version or the approved version. This will identify any changes that have been made without proper authorization or documentation. Tracing PCRs to logs or vice versa will only verify that the authorized changes have been recorded, but not detect any unauthorized changes. References: Standards, Guidelines, Tools and Techniques - ISACA, section “IS Audit and Assurance Tools and Techniques”

 A web proxy server for corporate connections to external resources reduces organizational risk by anonymizing users through changed IP addresses. A web proxy server is an intermediarybetween the web and client devices, that can provide proxy services to a client or a group of clients1. One of the main benefits of using a web proxy server is that it allows users to change their IP address andlocation, circumventing geoblocking and hiding their identity from the target website2.

Anonymizing internal IP addresses is important for online security, as it helps protect the organization from several threats. If an attacker controls a server that employees connect to, the outgoing IP address of the organization’s router is logged on the server. This IP address can be used by the attacker to launch a denial-of-service (DoS) attack or to create more targeted attacks such as phishing2. With a web proxy server, the IP shown in web logs is the web proxy’s, which means an attacker would not have access to theorganization’s router outgoing IP address2.

Anonymizing outgoing IP addresses is also important when carrying out sensitive actions online, such as law enforcement investigations or competitive intelligence. A web proxy server can help users avoid exposing their internal IP address that leads back to their organization, and instead use a third-party web proxy that provides more anonymity2.

The other options are not directly related to reducing organizational risk by using a web proxy server. Providing multi-factor authentication for additional security (option B) is a benefit of some web proxy servers, but it is not the main purpose of using a web proxy server3. Providing faster response than direct access(option C) is a benefit of some web proxy servers that cache content forbetter data transfer speeds and less bandwidth usage, but it is not directly related to reducing organizational risk1. Load balancing traffic to optimize data pathways (option D) is a benefit of some web proxy servers that distribute traffic across multiple servers, but it is not directly related to reducing organizational risk4.

Validation of rules by the business is the most helpful in establishing a baseline for measuring data quality because it ensures that the rules reflect the business needs and expectations. Validation of rules by the business also helps to identify and resolve any inconsistencies or conflicts among different data sources or stakeholders. Input from customers, industry standard business definitions and built-in data error prevention application controlsare useful for improving data quality, but they are not sufficient for establishing a baseline. References: CISA Review Manual (Digital Version) 1, Chapter 5, Section 5.4.1

The answer B is correct because a system-generated list of staff and their project assignments, roles, and responsibilities is the most useful to an IS auditor performing a review of access controls for a document management system. A document management system is a software that helps organizations store, manage, and share documents electronically. Access controls are the mechanisms that restrict or allow access to the documents based on predefined criteria, such as user identity, role, or project. An IS auditor needs to verify that the access controls are properly configured and implemented to ensure the security, confidentiality, and integrity of the documents.

A system-generated list of staff and their project assignments, roles, and responsibilities can help the IS auditor to perform the following tasks:

Identify the users who have access to the document management system and their level of access (e.g., read-only, edit, delete, etc.).

Compare the actual access rights of the users with their expected or authorized access rights based on their roles and responsibilities.

Detect any anomalies, discrepancies, or violations in the access rights of the users, such as excessive or unauthorized access, segregation of duties conflicts, or dormant or inactive accounts.

Evaluate the effectiveness and efficiency of the access control policies and procedures, such as user provisioning, deprovisioning, authentication, authorization, auditing, etc.

The other options are not as useful as option B. Policies and procedures for managing documents provided by department heads (option A) are not reliable sources of information for an IS auditor because they may not reflect the actual practices or compliance status of the document management system. Previous audit reports related to other departments’ use of the same system (option C) are not relevant for an IS auditor because they may not address the specific issues or risks associatedwith the current department’s use of the document management system. Information provided by the audit team lead on the authentication systems used by the department (option D) is not sufficient for an IS auditor because authentication is only one aspect of access control and it does not provide information on the authorization or auditing of the document access.
