Assessment Title

Rule Text

RHEL 10 must not have the "gdm" package installed.

Description

Discussion Text

Unnecessary service packages must not be installed to decrease the attack surface of the system. A graphical environment is unnecessary for certain types of systems including a virtualization hypervisor.

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

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.

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.stig.rhel10os:def:280950

if ! command -v rpm &> /dev/null; then
  echo "FAIL"
  exit 1
fi

if rpm -q gdm &> /dev/null; then
  echo "FAIL"
  exit 1
fi

echo "PASS"
exit 0

Remediation

Configure RHEL 10 to not have the "gdm" package installed with the following command:

$ sudo dnf -y remove gdm
