Description
max_log_file (size in megabytes) multiplied by num_logs must make full use of the auditd storage volume (separate to the root partition). If max_log_file_action is set to ROTATE or KEEP_LOGS then num_logs must be set to a value between 2 and 99.

Check Text (C-269530r1050413_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.

Fix Text (F-73462r1049941_fix)

Configure AlmaLinux OS 9 to make full use of the auditd storage volume with rotation enabled. Add or update the following line ("num_logs" can be set to a number between 2 and 99) in the "/etc/audit/auditd.conf" file: num_logs = 5
