UBTU-16-020030 - The Ubuntu operating system must notify the System Administrator (SA) and Information System Security Officer (ISSO) (at a minimum) via email when allocated audit record storage volume reaches 75% of the repository maximum audit record storage capacity - action_mail_acct

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.

Solution

Configure the operating system to immediately notify the SA and ISSO (at a minimum) via email when allocated audit record storage volume reaches 75% of the repository maximum audit record storage capacity.

Edit '/etc/audit/auditd.conf' and set the 'space_left_action' parameter to 'exec', 'email', or 'syslog'. 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).
