Information
If security personnel are not notified immediately when storage volume reaches 75% utilization, they are unable to plan for audit record storage capacity expansion.
NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.
Solution
Edit /etc/audit/auditd.conf and set the space_left_action parameter to "exec" or "email".
If the space_left_action parameter is set to "email" set the action_mail_acct parameter to an e-mail address for the System Administrator (SA) and Information System Security Officer (ISSO).
If the space_left_action parameter is set to "exec", make sure the command being execute notifies the System Administrator (SA) and Information System Security Officer (ISSO).
Edit /etc/audit/auditd.conf and set the space_left parameter to be, at least, 25% of the repository maximum audit record storage capacity.
