Discussion

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.

Check

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

If a TPM is not found or is not ready for use, this is a finding.

Fix

Ensure systems have a TPM that is configured for use. (Version 2.0 supports Credential Guard.)

The TPM must be enabled in the firmware.

Run "tpm.msc" for configuration options in Windows.
