Title

The AIX /var/spool/cron/atjobs directory must be group-owned by cron. (Cat II impact)

Discussion

Unauthorized group ownership of the /var/spool/cron/atjobs directory could permit unauthorized users the ability to alter atjobs and run automated jobs as privileged users. Failure to set proper permissions of the /var/spool/cron/atjobs directory provides 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 ownership of the /var/spool/cron/atjobs directory using command: # ls -ld /var/spool/cron/atjobs The above command should yield the following output: drw-r----- 1 bin cron 993 Mar 11 07:04 /var/spool/cron/atjobs If the group owner of the "atjobs" directory is not "cron", this is a finding.

Fix Text

Change the group ownership of the "atjobs" directory to cron using command: # chgrp cron /var/spool/cron/atjobs
