Discussion

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 max_log_file must be set to a value that makes the most use of the storage available.

Check Content

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 max_log_file /etc/audit/auditd.conf

max_log_file = 8

If the value of the "max_log_file" option is not sufficiently large to maximize the use of the storage volume, is commented out, or is missing, this is a finding.

Fix Text

Configure AlmaLinux OS 9 to make full use of the auditd storage volume with rotation enabled.
 
Add or update the following line in the "/etc/audit/auditd.conf" file to a value large enough to make efficient use of the auditd storage volume:
 
max_log_file = 100
