Verify User Who Owns /etc/at.allow file

An XCCDF Rule

Description

If /etc/at.allow exists, it must be owned by root. To properly set the owner of /etc/at.allow, run the command:

$ sudo chown root /etc/at.allow

Rationale

If the owner of the at.allow file is not set to root, the possibility exists for an unauthorized user to view or edit sensitive information.
