| Check Text (C-73561r1049940_chk) |
| Verify that AlmaLinux OS 9 is configured to make full use of the auditd storage volume when rotation is enabled, with the following command: $ grep num_logs /etc/audit/auditd.conf num_logs = 5 If the value of the "num_logs" option is not between 2 and 99, is commented out, or is missing, this is a finding. |
