BIOS Guard

The platform must implement hardware controls to provide the platform manufacturer a robust mechanism to prevent unauthorized flash updates, while still allowing platform manufacturer approved updates. Intel® Platform Protection Technology with BIOS Guard accomplishes this by providing a very robust environment from which signed update images can be cryptographically verified and host flash writes can be done. Furthermore, a BIOS Guard enabled system does not allow host flash writes from any other environment.
