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