Windows Server 2019 domain-joined systems must have a Trusted Platform Module (TPM) enabled and ready for use.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity

Description
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 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.

Details

Check Text (C-205848r991589_chk)

For standalone or nondomain-joined systems, this is NA. 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.

Fix Text (F-6113r355907_fix)

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.
