4.1.2.2 Ensure audit logs are not automatically deleted

Information

The max_log_file_action setting determines how to handle the audit log file reaching the max file size. A value of keep_logs will rotate the logs but never delete old logs.

Rationale:

In high security contexts, the benefits of maintaining a long audit history exceed the cost of storing the audit history.

Solution

Set the following parameter in /etc/audit/auditd.conf:

max_log_file_action = keep_logs
