CISA - Certified Information Systems Auditor Practice Questions: Information Systems Auditing Process Domain

Correct Answer: B

Explanation: A well-defined incident escalation procedure (B) is critical for ensuring that incidents are addressed promptly and appropriately, minimizing potential damage. While having a dedicated team (D) and providing training (A) are important, the escalation procedure directly impacts the timeliness and effectiveness of the response. Regular updates to the plan (C) are necessary but do not ensure immediate response effectiveness.

Correct Answer: B

Explanation: The primary objective of a data classification policy is to facilitate the appropriate handling of data based on its sensitivity and criticality. This ensures that data is protected according to its value and risk. While compliance, roles, and retention are important, they are secondary to the core purpose of data classification.

Correct Answer: D

Explanation: The most important aspect of an effective risk assessment is its alignment with the organization's risk appetite, ensuring that risks are managed within acceptable levels. Option A is important for regular updates but not as crucial as alignment with risk appetite. Option B ensures comprehensive input but does not guarantee effectiveness. Option C is a method choice and may not suit all organizations.

Correct Answer: C

Explanation: The primary concern for an IS auditor should be that the application meets the business requirements and security standards. This ensures that the application will function as intended and protect sensitive financial data. While using the latest programming language and staying within budget are important, they are not as critical as meeting business and security needs. High turnover may affect development, but it is not the primary concern.

Correct Answer: C

Explanation: The auditor should focus on assessing whether the system's performance meets the expected benefits as this directly relates to the success and effectiveness of the implementation. While budget comparison, training records, and vendor compliance are part of the review, the key measure of success is whether the system delivers the expected benefits.

Correct Answer: C

Explanation: The primary concern should be that users have access to only the data necessary for their job functions, following the principle of least privilege. This minimizes the risk of unauthorized access and data breaches. While multifactor authentication, regular access reviews, and logging are important security measures, ensuring appropriate access levels is fundamental to effective access control.

Correct Answer: A

Explanation: The most significant risk of not regularly testing the DRP is increased recovery time in the event of a disaster. Regular testing helps identify weaknesses and ensures that the plan is effective and can be executed efficiently. While non-compliance and outdated information are concerns, the primary risk is the potential delay in recovery efforts.

Correct Answer: B

Explanation: The primary risk of not regularly reviewing IDS logs is the delayed detection of security breaches. Regular review of logs is crucial for identifying and responding to potential security incidents in a timely manner. While false positives and costs are concerns, they do not pose as immediate a risk as delayed breach detection. Reduced network performance is not directly related to log review.

Correct Answer: A

Explanation: The primary concern with undocumented emergency changes is the potential for unauthorized changes, as this can lead to security vulnerabilities, data integrity issues, and non-compliance with regulatory requirements. While the lack of a formal policy (B) and staff training (D) are important, they are secondary to the risk of unauthorized changes. The inability to track system performance impact (C) is a consequence but not the primary risk.

Correct Answer: C

Explanation: Aligning the risk assessment with business objectives (C) ensures that the risks identified are relevant to the organization's goals and priorities, making the assessment more effective. Conducting it annually (A) or using a standardized tool (D) are procedural aspects that do not guarantee effectiveness. Communication to all employees (B) is valuable but secondary to alignment with business objectives.
