Assessment Script Powered by AISandbox-executed

A standalone Shell script to assess this control automatically. Review before running it in your environment.

Syntax-checked and actually executed in an isolated sandbox (not the real system this checks) — confirmed to run without errors.

#!/bin/sh
# OVAL definition: oval:mil.disa.fso.hpux11:def:193
if [ ! -d "/var/spool/cron/atjobs" ]; then echo "PASS"; exit 0; fi
if [ $(stat -c "%G" /var/spool/cron/atjobs) = root ] || [ $(grep -E "^bin:[^:]*:" /etc/group | cut -d: -f3) -eq $(stat -c "%g" /var/spool/cron/atjobs) ] || [ $(grep -E "^sys:[^:]*:" /etc/group | cut -d: -f3) -eq $(stat -c "%g" /var/spool/cron/atjobs) ]; then echo "PASS"; exit 0; else echo "FAIL"; exit 1; fi

Remediation

Change the group ownership of the file to root, bin, sys or other.

# chgrp root /var/spool/cron/atjobs
