Configure the audit log and audit log directory to be protected from unauthorized read access, by setting the correct owner as "root" with the following command:
$ sudo chgrp root [audit_log_file]
Replace "[audit_log_file]" to the correct audit log path, by default this location is "/var/log/audit/audit.log."
