Implementatie
20u (tech: 12u)
Van toepassing op:
✓ Azure AD
✓ Sentinel
✓ Sentinel
Identity is primary aanvalsvector. Monitoring detecteert: account compromises, privilege escalation, insider threats, compliance schendingen. Azure AD logt naar Sentinel voor SIEM correlation, automated response, long-term retention.
PowerShell Modules Vereist
Primary API: Microsoft Graph
Connection:
Required Modules: Microsoft.Graph.Reports
Connection:
Connect-MgGraphRequired Modules: Microsoft.Graph.Reports
Implementatie
Monitoring stack: Azure AD logt → Sentinel (SIEM), Workbooks voor dashboards, Alert rules (suspicious sign-ins, privilege changes, break-glass usage), Automated response (Schakel uit account, revoke sessions), Compliance reports (MFA coverage, passwordless adoption, risky users).
- Azure AD diagnostic settings → Verzend to Sentinel (all loggen categories)
- Sentinel alert rules: Suspicious sign-ins, admin changes, MFA failures
- Workbooks: Identity security dashboard, Compliance overview
- Automated response playbooks voor common scenarios
Vereisten
- Azure AD Premium P1/P2
- Azure Sentinel workspace
- Security Operations Center (SOC) capacity
- incidentrespons procedures
Implementatie
Gebruik PowerShell-script reporting-monitoring.ps1 (functie Invoke-Remediation) – Monitoring setup.
- Azure AD diagnostic settings → Verzend to Sentinel (all loggen categories)
- Sentinel alert rules: Suspicious sign-ins, admin changes, MFA failures
- Workbooks: Identity security dashboard, Compliance overview
- Automated response playbooks voor common scenarios
Monitoring
Gebruik PowerShell-script reporting-monitoring.ps1 (functie Invoke-Monitoring) – Controleren.
Daily: Alert triage, Weekly: Trend analysis, Monthly: Compliance reports, Quarterly: Review met management
Compliance en Auditing
- BIO 12.04 - Logging
- ISO 27001 A.12.4 - logging en monitoring
- NIS2 art. 21 - Monitoring capabilities
Remediatie
Gebruik PowerShell-script reporting-monitoring.ps1 (functie Invoke-Remediation) – Herstellen.
Compliance & Frameworks

Risico zonder implementatie
Risico zonder implementatie
High: Identity attacks undetected = prolonged compromise (months dwell time), slow incident response, compliance violations (NIS2 24-uur notification). Blind spot identity security. Het risico is HOOG - attack detection.
Management Samenvatting
Identity Reporting & Monitoring: Entra ID logs → Sentinel SIEM, Alert rules (suspicious sign-ins, privilege escalation, risky users, failed MFA), Dashboards (identity security posture), Automated response (block risky users, revoke sessions), Workbooks (identity analytics). Activatie: Entra ID → Diagnostic settings → Stream to Sentinel + Alert rules. Kosten: Sentinel ingestion. Verplicht BIO 16.01, NIS2. Implementatie: 12-20 uur. Essential identity threat detection.
