What it detects

This rule detects Entra ID operations that add cross-tenant partners, invite external users, or create access packages, overlooked entry points into Microsoft Azure that adversaries abuse for persistence per Red Canary. These identity changes can silently grant outside principals durable access to a tenant, so unexpected occurrences should be validated against approved administrative activity.
