Insider threats (malicious of negligent) veroorzaken 34% van datalekes. IRM detecteert: abnormal file downloads, mass deletions, external sharing spikes, en departure risk (exiting employees). Machine learning identificeert patterns.
PowerShell Modules Vereist
Primary API: Microsoft Graph
Connection:
Required Modules: Microsoft.Graph
Connection:
Connect-MgGraphRequired Modules: Microsoft.Graph
Implementatie
IRM policies: departing employees (90 days before/after), data theft, Gegevensleks, offensive behavior. Triggers: HR connector (termination dates), DLP overtredingen en alerts, abnormal activities. Privacy-preserving: pseudonymized Totdat investigation.
Vereisten
- M365 E5 Compliance
- HR data connector
- Insider Risk Administrator rol
- Privacy impact beoordeling
Implementatie
Gebruik PowerShell-script insider-risk-management.ps1 (functie Invoke-Remediation) – IRM setup.
Purview → Insider risicobeheer: policies, HR connector, analytics, alert triage workflow.
monitoring
Gebruik PowerShell-script insider-risk-management.ps1 (functie Invoke-Monitoring) – Controleren.
monitor: alerts, cases, departing employee risks, investigation status.
Compliance en Auditing
- BIO 12.04 - monitoring
- ISO 27001 A.12.4.1
- Privacy regulations (pseudonymization)
Remediatie
Gebruik PowerShell-script insider-risk-management.ps1 (functie Invoke-Remediation) – Herstellen.
Compliance & Frameworks
- BIO: 12.04.02 - User activity monitoring
- ISO 27001:2022: A.12.4.1 - Gebeurtenissen logging en audittrails
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).

High: Insider threats undetected = data exfiltration by departing employees, IP theft, sabotage. 34 procent breaches insider-related. Verizon DBIR: insiders = significant threat. Het risico is HOOG - insider threat detection.
Management Samenvatting
Insider Risk Management: ML-powered detection risky user behavior (mass downloads, unusual access patterns, departing employee activity). Alerts: data exfiltration, policy violations, risky file activities. Vereist: M365 E5 Compliance. Privacy-sensitive - legal/HR/Works Council approval. Activatie: Purview → Insider Risk → Policies (departing users, data theft, leaks). Kosten: E5 Compliance. Implementatie: 24-64 uur (policies + privacy review + HR training). Essential insider threat detection - 34% breaches insider-related.
- Implementatietijd: 64 uur
- FTE required: 0.25 FTE
