Certified Information Security Manager (CISM) — Question 188

Which of the following is the MOST effective way to help assure the integrity of an organization's accounting system?

Answer options

• A. Performing frequent security reviews of the audit log
• B. Implementing two-factor authentication
• C. Conducting an annual security audit of the system
• D. Providing security awareness training to accounting staff

Correct answer: A

Explanation

Performing frequent security reviews of the audit log is crucial as it helps in detecting any unauthorized access or anomalies in real-time, thus maintaining the integrity of the accounting system. While two-factor authentication, annual audits, and training are important security measures, they do not provide the same level of ongoing monitoring and immediate detection of potential issues as frequent log reviews do.
