Assessment Title

Rule Text

The /etc/access.conf file must have a privileged group owner.

Description

Discussion Text

Depending on the access restrictions of the /etc/access.conf file, if the group owner were not a privileged group, it could endanger system security.

How this relates to the STIG checklist: STIG vs SCAP benchmark.

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:mil.disa.fso.rhel11:def:15
if [ ! -e "/etc/security/access.conf" ]; then echo "PASS"; exit 0; fi; if [ "$(stat -c "%G" /etc/security/access.conf)" = "root" ] || [ "$(stat -c "%G" /etc/security/access.conf)" = "bin" ] || [ "$(stat -c "%G" /etc/security/access.conf)" = "sys" ]; then echo "PASS"; exit 0; else echo "FAIL"; exit 1; fi

Remediation

Use the chgrp command to ensure the group owner is root, sys, or bin.
(for example:
# chgrp root /etc/security/access.conf

).
