This document discusses five methods for performing cloud discovery with Microsoft Cloud App Security (MCAS): 1) snapshot reports, 2) Microsoft Defender for Endpoint, 3) secure web gateway, 4) Cloud Discovery API, and 5) automatic log upload. It focuses on option 5, describing how to deploy a log collector to automatically upload firewall/proxy logs to MCAS for continuous reporting on cloud app usage. The key steps are installing Docker on Windows, Linux on-premises or in Azure; configuring the log collector VM; and allowing network access for log ingestion and uploads to MCAS.
