The AIX /var/spool/cron/atjobs directory must have a mode of 0640 or less permissive.

Incorrect permissions 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 the mode of the /var/spool/cron/atjobs directory using command:

# ls -ld /var/spool/cron/atjobs drw-r----- 1 daemon daemon 993 Mar 11 07:04 /var/spool/cron/atjobs

If the directory has a mode more permissive than "0640", this is a finding.

Change the mode of the /var/spool/cron/atjobs directory: # chmod 640 /var/spool/cron/atjobs
