Rule Text

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

Description

Discussion Text

The "/etc/shadow-" file is a backup file of "/etc/shadow", and as such contains the list of local system accounts and 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.

if [ -e /etc/shadow- ] && [ -r /etc/shadow- ] && [ $(stat -c "%G" /etc/shadow-) = "root" ]; then echo "PASS"; exit 0; else echo "FAIL"; exit 1; fi

Remediation

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

$ sudo chgrp root /etc/shadow-
