CISA Leak Questions

The best audit evidence that a firewall is configured in compliance with the organization’s security policy is to review the rule base. The rule base is a set of rules that defines the criteria for allowing or denying network traffic through the firewall. By reviewing the rule base, the auditor can verify if the firewall configuration matches the security policy requirements and objectives. Analyzing how the configuration changes are performed, analyzing log files, and performing penetration testingare useful audit techniques, but they do not provide direct evidence of the firewall configuration compliance. References: CISA Review Manual (Digital Version)1, page 383.

The best recommendation to address the risk of privileged application accounts with passwords set to never expire in a 24/7 processing environment is to introduce database access monitoring into the environment. Database access monitoring is a security control that tracks and records all activities and transactions performed on a database, especially by privileged users or accounts. Database access monitoring can help address the risk of privileged application accounts with passwords set to never expire by detecting and alerting any unauthorized or abnormal access or actions on the database. The other options are not as effective as database access monitoring in addressing the risk, as they may cause disruption to the business or violate the access management policy. Modifying applications to no longer require direct access to the database is a complex and costly solution that may affect the functionality or performance of the applications, and it may not be feasible or practical in a 24/7 processing environment. Modifying the access management policy to make allowances for application accounts is a risky solution that may create exceptions or loopholes in the policy, and it may not comply with the best practices or standards for password management. Scheduling downtime to implement password changes is a disruptive solution that may affect the availability or continuity of the systems or applications, and it may not be acceptable or possible in a 24/7 processing environment. References: CISA Review Manual (Digital Version), Chapter 5, Section 5.2.4

This is because audit trails are records of system activity and user actions that can provide evidence of the validity and integrity of transactions and data in a financial application system. Audit trails can help to ensure compliance with laws, regulations, policies, and standards, as well as to detect and prevent fraud, errors, or misuse of information. Audit trails can also facilitate auditing, monitoring, and evaluation of the financial application system’s performance and controls1.

The application should meet the organization’s requirements (A) is not the best answer, because it is a general and obvious criterion that applies to any application system acquisition, not a specific and important recommendation for a financial application system. The organization’s requirementsshould be clearly defined and documented in the RFP, but they may not necessarily include audit trails as a design feature.

Potential suppliers should have experience in the relevant area © is not the best answer, because it is a factor that affects the selection of the supplier, not the design of the financial application system. The experience and reputation of potential suppliers should be evaluated and verified during the RFP process, but they may not guarantee that the supplier will include audit trails in the design.

Vendor employee background checks should be conducted regularly (D) is not the best answer, because it is a measure that affects the security and trustworthiness of the vendor, not the design of the financial application system. Vendor employee background checks should be performed as part of the vendor management and due diligence process, but they may not ensure that the vendor will include audit trails in the design.
