Control: 3.1.1.2 Ensure that Microsoft Defender for Cloud Apps integration with Microsoft Defender for Cloud is Selected

Description

This integration setting enables Microsoft Defender for Cloud Apps (formerly 'Microsoft Cloud App Security' or 'MCAS' - see additional info) to communicate with Microsoft Defender for Cloud.

Microsoft Defender for Cloud offers an additional layer of protection by using Azure Resource Manager events, which is considered to be the control plane for Azure. By analyzing the Azure Resource Manager records, Microsoft Defender for Cloud detects unusual or potentially harmful operations in the Azure subscription environment. Several of the preceding analytics are powered by Microsoft Defender for Cloud Apps. To benefit from these analytics, subscription must have a Cloud App Security license.

Microsoft Defender for Cloud Apps works only with Standard Tier subscriptions.
