Windows endpoints zijn primary attack target. Comprehensive security baseline voorkomt: ransomware via ASR rules en Defender, data theft via BitLocker versleuteling, Netwerk aanvallen via Firewall, en exploits via Windows security hardening. Zonder baseline zijn endpoints vulnerable.
PowerShell Modules Vereist
Primary API: Microsoft Graph
Connection:
Required Modules: Microsoft.Graph.DeviceManagement
Connection:
Connect-MgGraphRequired Modules: Microsoft.Graph.DeviceManagement
Implementatie
Security baseline omvat: BitLocker (OS + data drives, AES-256, TPM), Windows Defender (realtime bescherming, cloud-delivered, PUA, ASR rules), Windows Firewall (all profiles ingeschakeld, inbound blocked), AppLocker/WDAC (application control), Security baselines (CIS/Microsoft), en Intune compliance policies.
Vereisten
- Windows 10/11 Pro/Enterprise
- Intune
- Defender voor Endpoint
- TPM 2.0
Implementatie
Gebruik PowerShell-script windows-security.ps1 (functie Invoke-Remediation) – Windows security baseline deployment.
Implementeer via Intune: Security baselines, BitLocker policies, Defender configuration, ASR rules, firewallregels, Compliance policies.
monitoring
Gebruik PowerShell-script windows-security.ps1 (functie Invoke-Monitoring) – Controleren.
monitor: compliance rate, BitLocker versleuteling, Defender bescherming, ASR blocks, malware detections.
Compliance en Auditing
- CIS Windows Benchmark
- BIO 12.02 - Endpoint bescherming
- ISO 27001 A.8.7
- NIS2 Artikel 21
Remediatie
Gebruik PowerShell-script windows-security.ps1 (functie Invoke-Remediation) – Herstellen.
Compliance & Frameworks
- CIS M365: Control Windows Benchmark (L1) - Comprehensive Windows hardening
- BIO: 12.02.01, 10.01.01 - Bescherming tegen malware en versleuteling
- ISO 27001:2022: A.8.7, A.8.24 - Endpoint bescherming
- NIS2: Artikel - Endpoint security
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).

Critical: Unprotected endpoints = ransomware (#1 threat), data theft device loss, malware infections. Average incident cost: €500K-5M. 70 procent ransomware enters via endpoints. Compliance: CIS, BIO 12.02, NIS2. Het risico is KRITIEK - endpoint security foundation.
Management Samenvatting
Windows Security Baseline: BitLocker (full disk encryption), Microsoft Defender (antimalware + EDR), Attack Surface Reduction rules (blocks Office macros, script execution), Windows Firewall (block inbound), Credential Guard, Application Control (AppLocker/WDAC), Exploit protection. Activatie: Intune → Endpoint security → Security baseline deployment. Gratis (Defender included M365 E3+). Verplicht CIS, BIO 12.02, NIS2. Implementatie: 80-120 uur (comprehensive baseline + pilot + rollout). CRITICAL security foundation - endpoints = #1 attack vector.
- Implementatietijd: 120 uur
