Fix Recommendation

Configure OL 9 to shut down by default upon audit failure (unless availability is an overriding concern).

Add or update the following line (depending on configuration "disk_full_action" can be set to "SYSLOG" or "SINGLE" depending on configuration) in "/etc/audit/auditd.conf" file:

disk_full_action = HALT

If availability has been determined to be more important, and this decision is documented with the information system security officer (ISSO), configure the operating system to notify SA staff and ISSO staff in the event of an audit processing failure by setting the "disk_full_action" to "SYSLOG".

Check Contents

Verify that OL 9 takes the appropriate action when the audit storage volume is full.

Check that OL 9 takes the appropriate action when the audit storage volume is full with the following command:

$ sudo grep disk_full_action /etc/audit/auditd.conf
disk_full_action = HALT

If the value of the "disk_full_action" option is not "SYSLOG", "SINGLE", or "HALT", or the line is commented out, ask the system administrator (SA) to indicate how the system takes appropriate action when an audit storage volume is full. If there is no evidence of appropriate action, this is a finding.
