Fix Recommendation

Configure Amazon Linux 2023 to take action when the audit log storage volume reaches 75 percent of the maximum storage capacity.

Edit "/etc/audit/auditd.conf" and ensure the parameter "space_left = 25%" is configured.

Check Contents

Verify Amazon Linux 2023 takes action when allocated audit record storage volume reaches 75 percent of the repository maximum audit record storage capacity with the following command:

$ sudo grep -w space_left /etc/audit/auditd.conf
space_left = 25%

If the value of the "space_left" keyword is not set to 25 percent of the storage volume allocated to audit logs, or if the line is commented out, ask the system administrator (SA) to indicate how the system is providing real-time alerts to the SA and information system security officer (ISSO). If the "space_left" value is not configured to the correct value, this is a finding.
