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

At the command line, run the following command to verify auditd is alerting when low disk space is detected:

# grep '^space_left' /etc/audit/auditd.conf

Expected result:

space_left = 25%
space_left_action = SYSLOG

If the output does not match the expected result, this is a finding.

Fix Text

Navigate to and open:

/etc/audit/auditd.conf

Ensure the "space_left" and "space_left_action" lines are uncommented and set to the following:

space_left = 25%
space_left_action = SYSLOG

At the command line, run the following command:

# pkill -SIGHUP auditd
