Assessment Title

Rule Text

The services file must be owned by root or bin.

Description

Discussion Text

Failure to give ownership of sensitive files or utilities to root or bin provides the designated owner and unauthorized users with the potential to access sensitive information or change the system configuration which could weaken the system's security posture.

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

SCC Automation Reference

The reconstructed evaluation script behind this rule's OVAL check(s) — every module a compound check combines, with this rule's own concrete values and DISA's SCC tool's real per-module mechanism curated from static teardown of SCC releases.

# Test owner of /etc/services is root

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:235
if [ ! -f "/etc/services" ]; then echo "PASS" && exit 0; fi
if [ $(stat -c "%u" "/etc/services") = "0" ] || [ $(id -u bin) -eq $(stat -c "%u" "/etc/services") ]; then echo "PASS" && exit 0; else echo "FAIL" && exit 1; fi

Remediation

Change the ownership of the services file to root or bin.
# chown root /etc/services
