Verify Owner on cron.deny

An XCCDF Rule

Description

To properly set the owner of /etc/cron.deny, run the command: 

$ sudo chown 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 user to prevent unauthorized changes.
