4.1.1.1 Ensure audit log storage size is configured

Information

Configure the maximum size of the audit log file. Once the log reaches the maximum size, it will be rotated and a new log file will be started.

Rationale:

It is important that an appropriate size is determined for log files so that they do not impact the system and audit data is not lost.

Solution

Set the following parameter in /etc/audit/auditd.conf in accordance with site policy:

max_log_file = <MB>

Additional Information:

The max_log_file parameter is measured in megabytes.
