Rule Text

RHEL 10 must be configured so that the "/etc/gshadow-" file is owned by "root".

Description

Discussion Text

The "/etc/gshadow-" file is a backup of "/etc/gshadow", and as such contains group password hashes. Protection of this file is critical for 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

if [ -e /etc/gshadow- ] && [ $(stat -c "%u" /etc/gshadow-) -eq 0 ]; then echo "PASS"; else echo "FAIL"; fi
exit 0

Remediation

Configure RHEL 10 so that the owner of the "/etc/gshadow-" file is set to "root" by running the following command:

$ sudo chown root /etc/gshadow-
