Verify Permissions on /etc/cron.allow file

An XCCDF Rule

Description

If /etc/cron.allow exists, it must have permissions 0640 or more restrictive. To properly set the permissions of /etc/cron.allow, run the command: 

$ sudo chmod 0640 /etc/cron.allow

Rationale

If the permissions of the cron.allow file are not set to 0640 or more restrictive, the possibility exists for an unauthorized user to view or edit sensitive information.
