Title

Windows 11 systems must have a Trusted Platform Module (TPM) enabled.

Control

Verify the system has a TPM and is ready for use. Run "tpm.msc". Review the sections in the center pane. "Status" must indicate it has been configured with a message such as "The TPM is ready for use" or "The TPM is on and ownership has been taken". TPM Manufacturer Information - Specific Version = 2.0 If a TPM is not found or is not ready for use, this is a finding.

Discussion

Credential Guard uses virtualization-based security to protect information that could be used in credential theft attacks if compromised. There are a number of system requirements that must be met in order for Credential Guard to be configured and enabled properly. Without a TPM enabled and ready for use, Credential Guard keys are stored in a less secure method using software.

Fix

Ensure systems have a TPM that is configured for use. (Versions 2.0 supports Credential Guard.) The TPM must be enabled in the firmware. Run "tpm.msc" for configuration options in Windows.
