Verify the audit system off-loads audit records if the SUSE operating system storage volume becomes full. Check that the records are properly off-loaded to a remote server with the following command: # sudo grep -i "disk_full_action" /etc/audisp/audisp-remote.conf disk_full_action = syslog If "disk_full_action" is not set to "syslog", "single", or "halt" or the line is commented out, this is a finding.
Configure the SUSE operating system to take the appropriate action if the audit storage is full. Add, edit, or uncomment the "disk_full_action" option in "/etc/audisp/audisp-remote.conf". Set it to "syslog", "single" or "halt" as in the example below: disk_full_action = syslog
