CISA Reviews Questions

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
