Title

The "at" directory must have mode 0755 or less permissive. (Cat II impact)

If the "at" directory has a mode more permissive than 0755, unauthorized users could be allowed to view or to edit files containing sensitive information within the "at" directory. Unauthorized modifications could result in Denial-of-Service to authorized "at" jobs.

Check Content

Check the mode of the "at" directory. Procedure: # ls -ld /var/spool/cron/atjobs /var/spool/atjobs /var/spool/at If the directory mode is more permissive than 0755, this is a finding.
