WN10-CC-000070 - Virtualization Based Security must be enabled on Windows 10 with the platform security level configured to Secure Boot or Secure Boot with DMA Protection.

Information

Virtualization Based Security (VBS) provides the platform for the additional security features, Credential Guard and Virtualization based protection of code integrity. Secure Boot is the minimum security level with DMA protection providing additional memory protection. DMA Protection requires a CPU that supports input/output memory management unit (IOMMU).

Solution

VBS, including Credential Guard, currently cannot be implemented in virtual desktop implementations (VDI) due to specific supporting requirements including a TPM, UEFI with Secure Boot, and the capability to run the Hyper-V feature within the virtual desktop.

For VDIs where the virtual desktop instance is deleted or refreshed upon logoff, this is NA.

Configure the policy value for Computer Configuration >> Administrative Templates >> System >> Device Guard >> 'Turn On Virtualization Based Security' to 'Enabled' with 'Secure Boot' or 'Secure Boot and DMA Protection' selected for 'Select Platform Security Level:'.
