Exam CISA Topic 3 Question 1294 Discussion

The auditor's best course of action after a security breach in which a hacker exploited a well-known vulnerability in the domain controller is to determine if the logs were monitored. Log monitoring is an essential control for detecting and responding to security incidents, especially when known vulnerabilities exist in the system. The auditor should assess if the logs were properly configured, collected, reviewed, analyzed, and acted upon by the responsible parties. Updating patches, monitoring network traffic, and classifying domain controllers for high availability are also important controls, but they are not directly related to the detection and response of the security breach.
