Id	d4f8a032-6d5b-4e9f-b3a0-8c2e4f7d0b6e
Rulename	Google SecOps - Multi-Event Correlated Alert
Description	Creates incidents in Microsoft Sentinel when Google Security Operations raises an active multi-event correlated alert (MULTI_EVENT, riskScore gte 40) at HIGH or CRITICAL severity. These alerts indicate complex attack patterns like lateral movement, staged persistence, or command-and-control identified by correlating multiple signals across a time window.
