UBTU-18-010006 - The Ubuntu operating system must immediately notify the SA and ISSO (at a minimum) when allocated audit record storage volume reaches 75% of the repository maximum audit record storage capacity - action_mail_acct

Details

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

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.
