Discussion

Cron daemon control files restrict the scheduling of automated tasks and must be protected. Unauthorized modification of the cron.deny file could result in Denial of Service to authorized cron users or could provide unauthorized users with the ability to run cron jobs.

Check Content

Check the group ownership of the file.

Procedure:
# ls -lL /etc/cron.deny

If the file is not group-owned by root, bin or sys this is a finding.

Fix Text

Change the group ownership of the file.
# chgrp root /etc/cron.deny
