Discussion

Without information about the outcome of events, security personnel cannot make an accurate assessment as to whether an attack was successful or if changes were made to the security state of the system. Event outcomes can include indicators of event success or failure and event-specific results (e.g., the security state of the information system after the event occurred). As such, they also provide a means to measure the impact of an event and help authorized personnel to determine the appropriate response.

Verify the audit event "status" is displayed:

The log file can be set by the "trail" variable in /etc/security/audit/config.

# grep trail /etc/security/audit/config
        trail = /audit/trail

Note: The default log file is /audit/trail.

Use the following command to display the audit events:

# /usr/sbin/auditpr -i <audit log file> -helRtcp
