What type of messages are found in the secure logs?

Secure logs specifically contain security-related messages, which typically include information about authentication attempts, user logins, and various security events that may indicate suspicious activity or breaches. These logs are essential for monitoring system security and ensuring that only authorized users have access to the resources.

For instance, secure logs track failed login attempts, the establishment of secure connections, and access to sensitive files or resources. This information is crucial for systems administrators to analyze security incidents and to maintain the overall integrity of the system.

The other options do not pertain to secure logs. Audio logs would relate to sound recording data, administrative command logs would focus on commands executed in the system, and file system error messages would document issues related to file storage and management. Each of these serves different purposes within system monitoring, but none belong to the category of secure logs.
