Discussion

If security personnel are not notified immediately when storage volume reaches 75 percent utilization, they are unable to plan for audit record storage capacity expansion.

Check Content

Determine if SLEM 5 auditd is configured to notify the SA and ISSO when the audit record storage volume reaches 75 percent of the storage capacity with the following command:

     > sudo grep -iw space_left /etc/audit/auditd.conf
     space_left = 25% 

If "space_left" is not set to "25%" or greater, this is a finding.

Fix Text

Configure SLEM 5 auditd service to notify the SA and ISSO immediately when audit storage capacity is 75 percent full.

Add or modify the following lines in the "/etc/audit/auditd.conf " file: 

space_left = 25%
