Fix Recommendation

Edit the /etc/audit/auditd.conf file and add or update the "overflow_action" option to one of "syslog", "single", or "halt":

overflow_action = syslog

The audit daemon must be restarted for changes to take effect.

Check Contents

Verify the audit system is configured to take an appropriate action when the internal event queue is full:

$ sudo grep -i overflow_action /etc/audit/auditd.conf

overflow_action = syslog

If the value of the "overflow_action" option is not set to "syslog", "single", "halt", or the line is commented out, ask the System Administrator to indicate how the audit logs are offloaded to a different system or media.

If there is no evidence that the transfer of the audit logs being offloaded to another system or media takes appropriate action if the internal event queue becomes full, this is a finding.
