Verify Group Who Owns cron.deny
An XCCDF Rule
Description
To properly set the group owner of /etc/cron.deny, run the command:
$ sudo chgrp root /etc/cron.deny
Rationale
Service configuration files enable or disable features of their respective services that if configured incorrectly can lead to insecure and vulnerable configurations. Therefore, service configuration files should be owned by the correct group to prevent unauthorized changes.
