Title

The AIX /var/spool/cron/atjobs directory must be owned by root or bin. (Cat II impact)

Discussion

Unauthorized 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 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 owner of the "atjobs" directory is not "root" or "bin", this is a finding.
