💼 Management Samenvatting

Windows configuratiebaseline design voor Windows 10/11 devices via Intune en groep beleid om enterprise security, compliance, en gebruikerservaring te waarborgen.

Van toepassing op:
✓ Windows 10
✓ Windows 11
✓ Intune

Windows endpoints zijn primary platform voor enterprise work. configuratiebaseline zorgt voor: (1) Security hardening - CIS Benchmark alignment, security features ingeschakeld (Defender, Firewall, BitLocker, credential Guard), (2) Compliance - Audit beleidsregels, logging, security baselines voor regulatory requirements, (3) gebruikerservaring - Corporate branding, Standaard applications, network configuration, (4) Management - Update beleidsregels, remote management, monitoring agents. Zonder configuratiebaseline: inconsistent beveiligingspositie, compliance hiaten, ondersteunen overhead, security vulnerabilities. CIS Windows Benchmarks bieden comprehensive configuration guidance - Level 1 (baseline) en Level 2 (high security).

PowerShell Modules Vereist
Primary API: Microsoft Graph
Connection: Connect-MgGraph
Required Modules: Microsoft.Graph.DeviceManagement

Implementatie

Windows configuratiebaseline omvat: Security Baseline (CIS Level 1/2), BitLocker versleuteling (XTS-AES 256), Windows Defender configuration (realtime bescherming, cloud-delivered bescherming, PUA blocking), firewallregels (Blokkeer inbound, loggen drops), credential Guard ingeschakeld, LSA bescherming, veilige Boot + TPM validatie, Audit beleidsregels (comprehensive logging), Update beleidsregels (automatische updates, feature update deferrals), Network configuration (WiFi, VPN profiles), Application beleidsregels (AppLocker/WDAC voor application control), Privacy settings (telemetry limited, consumer features disabled). implementeren via: Intune Security Baselines + aangepaste configuration profiles + groep beleid (hybrid environments).

Vereisten

  1. Microsoft Intune subscription
  2. Windows 10/11 Enterprise of Education
  3. Azure AD Join of Hybrid Azure AD Join
  4. TPM 2.0 voor BitLocker en credential Guard
  5. UEFI firmware voor veilige Boot
  6. PKI infrastructure voor certificaatn (optioneel maar aanbevolen)
  7. CIS Windows Benchmark referentie documentation

Implementatie

Gebruik PowerShell-script windows-configuration.ps1 (functie Invoke-Remediation) – Windows configuratiebaseline deployment.

Intune Security Baselines deployment:

  1. Intune → Endpoint security → Security baselines
  2. Deploy: Windows 11 Security Baseline (laTest version)
  3. Deploy: Microsoft Defender voor Endpoint baseline
  4. Deploy: Microsoft Edge baseline
  5. Customize: Organizational requirements (balance security vs usability)
  6. Assign: alle Windows devices
  7. monitor: compliance rapportage

aangepaste configuration profiles (supplement baselines):

  1. BitLocker: XTS-AES 256, TPM + PIN, recovery key escrow to Azure AD
  2. Windows Update: Quality updates automatic, Feature updates deferred (Test phase)
  3. Network: Corporate WiFi profiles, VPN (Always op VPN aanbevolen)
  4. Privacy: Telemetry is Security (1), consumer features disabled
  5. Applications: AppLocker rules of WDAC beleidsregels

monitoring

Gebruik PowerShell-script windows-configuration.ps1 (functie Invoke-Monitoring) – Controleren.

Comprehensive monitoring:

  1. Intune → Devices → Compliance dashboard
  2. Security baseline compliance percentage (target: >95%)
  3. Non-compliant devices → remediation workflows
  4. Configuration profile deployment status
  5. Windows Update compliance
  6. BitLocker versleuteling coverage
  7. Defender voor Endpoint integration - beveiligingspositie visibility

Compliance en Auditing

  1. CIS Windows 11 Enterprise Benchmark Level 1/2
  2. BIO 12.06 - Endpoint security configuration
  3. ISO 27001:2022 A.8.9 - configuratiebeheer
  4. ISO 27001:2022 A.8.19 - Installation of software op operational systems
  5. NIST SP 800-171 - configuratiebeheer
  6. NIS2 Artikel 21 - Security measures

Remediatie

Gebruik PowerShell-script windows-configuration.ps1 (functie Invoke-Remediation) – Herstellen.

Compliance & Frameworks

Automation

Gebruik het onderstaande PowerShell script om deze security control te monitoren en te implementeren. Het script bevat functies voor zowel monitoring (-Monitoring) als remediation (-Remediation).

Risico zonder implementatie

Risico zonder implementatie
High: Zonder Windows configuration baseline = inconsistent security, compliance violations (CIS, BIO, ISO 27001), unencrypted devices, weak authentication, missing security controls, excessive privileges, data leaks misconfigured privacy. Het risico is HOOG - enterprise baseline mandatory.

Management Samenvatting

Windows Configuration Baseline: Intune Security Baselines (CIS-aligned) + Custom profiles - BitLocker encryption, Defender hardening, Update management, Privacy controls, Firewall rules, User privileges (standard user), Authentication settings. Activatie: Intune → Endpoint security → Security baselines + Configuration profiles. Gratis (Intune included M365). Verplicht CIS, BIO 12.02, ISO 27001. Implementatie: 24-48 uur (baseline + pilot + validation). CRITICAL enterprise security foundation - non-negotiable.
