Verify Permissions on /etc/at.allow file

An XCCDF Rule

Description

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

$ sudo chmod 0640 /etc/at.allow

Rationale

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