Title

Cron and crontab directories must be group-owned by root, sys, bin or other. (Cat II impact)

Discussion

To protect the integrity of scheduled system jobs and to prevent malicious modification to these jobs, crontab files must be secured. Failure to give group-ownership of cron or crontab directories to a system group provides the designated group and unauthorized users with the potential to access sensitive information or change the system configuration which could weaken the system's security posture.

Check Content

Check the group owner of the crontab directories. # ls -lLd /var/spool/cron/crontabs If the directory is not group-owned by root, sys, bin or other, this is a finding.

Fix Text

Change the group owner of the crontab directories to root, sys, bin or other. # chown root /var/spool/cron/crontabs
