Fix Recommendation

Configure the Ubuntu operating system 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", "HALT" or "SINGLE") in "/etc/audit/auditd.conf" file:

disk_full_action = HALT

Restart the "auditd" service so the changes take effect:

$ sudo systemctl restart auditd.service

Check Contents

Verify the Ubuntu operating system 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, this is a finding.
