What type of log can be found under Audit Logs?

The correct answer is Authentication Logs. Audit logs serve to track actions and events concerning user access and administrative activities within a system. Authentication logs specifically record the details of user logins and access attempts, including successful and unsuccessful authentication events. This provides a clear accountability trail and enhances security by helping identify suspicious activities.

The nature of authentication logs as part of audit tracking emphasizes user verification processes, ensuring that only authorized personnel can access specific functions within the system. Monitoring these logs is crucial for understanding user behavior and maintaining security integrity within the organization's email systems.

While other types of logs, such as secure messaging, policy, and activity logs, are also important, they serve different functions in system monitoring and do not specifically pertain to user authentication events within the scope of audit logs. Secure messaging logs focus on the encryption and transmission of messages, policy logs center around compliance and rule enforcement, and activity logs detail user actions, but none of these align directly with the critical role that authentication logs play in tracking access and security measures.
