Title

The cron.deny file must not have an extended ACL. (Cat II impact)

Discussion

If file permissions for cron.deny are more permissive than 0700, sensitive information could be viewed or edited by unauthorized users.

Check Content

Check the permissions of the file. # ls -lL /etc/cron.d/cron.deny If the permissions include a "+", the file has an extended ACL and this is a finding.

Fix Text

Remove the extended ACL from the file. # chmod A- /etc/cron.d/cron.deny
