To determine the action that takes place if the disk is full on the remote server, use the following command: # grep -i disk_full_action /etc/audisp/audisp-remote.conf disk_full_action = single 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.
