Fix Recommendation

Configure the auditd service to take action in the event of allocated audit record storage volume reaches 95 percent of the repository maximum audit record storage capacity.

Edit the following line in "/etc/audit/auditd.conf" to ensure that the system is forced into single user mode in the event the audit record storage volume is about to reach maximum capacity:

admin_space_left_action = single

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

Restart auditd:
$ sudo service auditd restart

Check Contents

Verify that OL 9 is configured to take action in the event of allocated audit record storage volume reaches 95 percent of the repository maximum audit record storage capacity with the following command:

$ sudo grep admin_space_left_action /etc/audit/auditd.conf
admin_space_left_action = single

If the value of the "admin_space_left_action" is not set to "single", or if the line is commented out, ask the system administrator (SA) to indicate how the system is providing real-time alerts to the SA and information system security officer (ISSO).

If there is no evidence that real-time alerts are configured on the system, this is a finding.
