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.

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.mozilla.firefox.rhel:def:360
if [ -f "$(grep -r '^\s*pref\(\"extensions.htmlaboutaddons.recommendations.enabled\"\s*,\s*false\s*;' ~/.mozilla/firefox/*.default-*/*.prefs.js)" ]; then echo "PASS"; else echo "FAIL"; fi
exit 0

Remediation

Ensure the preference “extensions.htmlaboutaddons.recommendations.enabled" is set and locked to the value of “false”.
