Title
The cron.deny file must be group-owned by root, bin, or sys. (Cat II impact)
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.d/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 to root, sys, or bin. Procedure: # chgrp root /etc/cron.d/cron.deny
