SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Windows endpoints ship with permissive default configurations that expand the attack surface and fail compliance audits. This Skill guides the full process of applying CIS Benchmark security baselines to Windows 10/11 and Server 2019/2022 endpoints, from GPO import through automated compliance validation.

Core Features & Use Cases

  • CIS Profile Selection: Choose between Level 1 (general enterprise) and Level 2 (high-security) benchmark profiles based on data classification.
  • GPO Baseline Deployment: Import CIS Build Kit GPOs into Active Directory and link them to target OUs with PowerShell commands.
  • Automated Compliance Validation: Run CIS-CAT Pro Assessor scans, schedule recurring assessments, and feed results to a SIEM for drift detection.
  • Use Case: A security team remediating SOC 2 audit findings imports the CIS Windows 11 L1 GPO baseline, validates a 95%+ CIS-CAT score, and documents exceptions with compensating controls.

Quick Start

Harden my Windows 11 workstations using the CIS Level 1 benchmark and show me how to validate compliance with CIS-CAT.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I harden Windows 11 with CIS Benchmark?▼

Import the CIS Build Kit GPO for your Windows version into Active Directory using Import-GPO, link it to the target OU, then validate with CIS-CAT Pro Assessor. Select Level 1 for general workstations or Level 2 for systems handling sensitive data.

What is the difference between CIS Level 1 and Level 2 profiles?▼

Level 1 provides practical hardening with minimal operational impact, covering password policy, audit policy, and firewall settings. Level 2 adds stricter controls like disabling Autoplay and restricting Remote Desktop, intended for endpoints handling PII, PHI, or PCI data.

How do I verify a CIS GPO is actually applied to endpoints?▼

Run gpresult /h report.html or Get-GPResultantSetOfPolicy on the target host and confirm the baseline appears under Applied GPOs. Also verify audit settings with auditpol /get /category:* since CIS 17.x subcategories require the SCENoApplyLegacyAuditPolicy override.

Can I apply CIS benchmarks to standalone Windows machines without a domain?▼

Yes, standalone systems cannot use domain GPOs, so apply baselines with Microsoft's LGPO.exe tool or manage them through Microsoft Intune. CIS benchmarks assume domain-joined endpoints by default.

Why does my CIS-CAT score not reflect real compliance gaps?▼

CIS-CAT only evaluates Scored items in the profile you selected, so running Level 1 hides missing Level 2 controls. An outdated benchmark XML also reports false passes, so match the benchmark version to your OS build.

When should I not use CIS Windows endpoint benchmarks?▼

Do not use this approach for Linux endpoints, which require the CIS Linux benchmark, or for cloud-native workloads that need CIS cloud benchmarks. Also avoid applying Level 2 broadly, since its restrictions break standard workstation workflows.
