Vulnerability Discussion

Secure Boot is a standard that ensures systems boot only to a trusted operating system. Secure Boot is required to support additional security features in Windows, including Virtualization Based Security and Credential Guard. If Secure Boot is turned off, these security features will not function.

Check

Devices that have UEFI firmware must have Secure Boot enabled.

Run "System Information".

Under "System Summary", if "Secure Boot State" does not display "On", this is a finding.

On server core installations, run the following PowerShell command:

Confirm-SecureBootUEFI

If a value of "True" is not returned, this is a finding.

Fix

Enable Secure Boot in the system firmware.
