The review of audit logs serves as a crucial control mechanism primarily because it identifies unauthorized access. By regularly examining audit logs, organizations can monitor user activities and detect any anomalies or irregular behaviors that suggest breaches or unauthorized access attempts. This proactive approach is essential in safeguarding sensitive information and maintaining the integrity of systems.

When unauthorized access is detected through audit logs, swift action can be taken to remediate security threats, thereby preventing potential data breaches and ensuring that the organization's assets are effectively protected. This function of audit log review adds a layer of oversight and enhances overall security posture.

While creating a record of actions, ensuring compliance with policies, and providing insights into system performance are also important functions of audit logs, their primary role in this context centers on identifying security incidents and threats, which is foundational for effective risk management in information systems.
