Description​

Microsoft Defender for Resource Manager scans incoming administrative requests to change your infrastructure from both CLI and the Azure portal.

Rationale​

Scanning resource requests lets you be alerted every time there is suspicious activity in order to prevent a security threat from being introduced.

Enabling Microsoft Defender for Resource Manager requires enabling Microsoft Defender for your subscription. Both will incur additional charges.

A Subscription is also marked as INCOMPLIANT if the Defender Plan for Resource Manager does not exist in the CMDB.

Default Value​

By default, Microsoft Defender for Resource Manager is not enabled.
