Credential Guard uses virtualization-based security to protect data that could be used in credential theft attacks if compromised. A number of system requirements must be met 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.
For stand-alone or nondomain-joined systems, this is not applicable. Verify the system has a TPM and it 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 or 1.2 If a TPM is not found or is not ready for use, this is a finding.
Ensure domain-joined systems have a TPM that is configured for use. (Versions 2.0 or 1.2 support Credential Guard.) The TPM must be enabled in the firmware. Run "tpm.msc" for configuration options in Windows.
