M365 Purview Security Compliance Signal

Collects alerts generated by Microsoft Purview (formerly Office 365 Security & Compliance Center) through the SecurityComplianceCenter provider. These alerts represent policy violations, compliance issues, and threats detected by Microsoft Purview's built-in detection capabilities including DLP policy matches, eDiscovery actions, retention policy violations, and other compliance-related events. This building block rule generates security events for correlation, threat hunting, and telemetry collection without creating standalone alerts, reducing alert fatigue while maintaining comprehensive visibility into Microsoft Purview's compliance and security detections.
