Description

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.

ℹ️ Check

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

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
