HP-UX 11.31 STIG: GEN003270 (in versions v1 r19 through v1 r13)

Title

The cron.deny file must be group-owned by root, bin, sys or other. (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

Determine the cron.deny file's group owner. # ls -lL /var/adm/cron/cron.deny If the file is not group-owned by root, bin sys or other, this is a finding.

Fix Text

Change the group-owner of the cron.deny file. # chgrp root /var/adm/cron/cron.deny
