Assessment Title

Rule Text

For systems capable of using GRUB, the system must be configured with GRUB as the default boot loader unless another boot loader has been authorized, justified, and documented using site-defined procedures.

Description

Discussion Text

GRUB is a versatile boot loader used by several platforms that can provide authentication for access to the system or boot loader.

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:443 compliance check
if [ -e /boot/grub/grub.conf ]; then echo "PASS"; exit 0; else echo "FAIL"; exit 1; fi

Remediation

Configure the system to use the GRUB bootloader or document, justify, and authorize the alternate bootloader.
