Verify Permissions on /etc/at.allow file
An XCCDF Rule
Description
If /etc/at.allow exists, it must have permissions 0600
or more restrictive.
To properly set the permissions of /etc/at.allow, run the command:
$ sudo chmod 0600 /etc/at.allow
Rationale
If the permissions of the at.allow file are not set to 0600 or more restrictive, the possibility exists for an unauthorized user to view or edit sensitive information.
