Description
This detection will trigger when a content search is initiated within the Office 365 Security and Compliance Center, a critical component in the suite’s governance, risk management, and compliance (GRC) capabilities. By monitoring the SearchCreated operation within the o365_management_activity logs, specifically under the SecurityComplianceCenter workload, this analytic flags the commencement of searches across the organization’s data, including emails, documents, and more, that reside in ExchangeLocations.
Detection logic
