Vulnerability Discussion

If action is not taken when storage volume reaches 75 percent utilization, the auditing system may fail when the storage volume reaches capacity.

Check

Verify RHEL 10 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 "admin_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 to indicate how the system is taking action if the allocated storage is about to reach capacity.

If the "space_left" value is not configured to the correct value, this is a finding.

Fix

Configure RHEL 10 to initiate an action when allocated audit record storage volume reaches 75 percent of the repository maximum audit record storage capacity by adding/modifying the following line in the /etc/audit/auditd.conf file:

space_left = 25%

Restart the audit daemon with the following command for the changes to take effect:

$ sudo service auditd restart
