Discussion

The "at" daemon control files restrict access to scheduled job manipulation and must be protected. Unauthorized modification of the at.deny file could result in Denial of Service to authorized "at" users or provide unauthorized users with the ability to run "at" jobs.

Check Content

Check the permissions of the file.
# ls -lL /etc/at.deny
If the file has a mode more permissive than 0600, this is a finding.

Fix Text

Change the mode of the file.
# chmod 0600 /etc/at.deny
