Additional Information

At the time of writing Microsoft Defender for IoT has been recently released. To ensure correct terminology, the Center for Internet Security (CIS) plans to include commands for this in v1.6. There are additional configurations for Microsoft Defender for IoT that allow for types of deployments called hybrid or local. Both run on your physical infrastructure. These complicated setups are mostly outside of the scope of a purely Azure benchmark. Please see the reference to consider these options for your organization.
