Comprehensive and Detailed Explanation From BIG-IP Administration Control Plane Administration do38cuments: While HA state is managed under "Device Management," the specific failover behavior of a traffic object is linked to its configuration.

On BIG-IP systems,authentication and authorization eventsare logged in/var/log/secure. This includes:

Successful and failedSSH login attempts

Invalid user authentication attempts

PAM (Pluggable Authentication Module) authentication failures

Access denials related to secure services

Why the other options are incorrect:

/var/log/messagescontains general system messages and service events, not detailed authentication failures.

/var/log/auditrecords administrative configuration changes (who changed what and when), not login attempts.

/var/log/ltmlogs traffic-management (TMM) and application-related events.

Therefore, the correct log file for investigatingunauthorized SSH login attemptsis/var/log/secure.
