What is a pre-requisite for configuring virtualization-based security (VBS)?

Configuring virtualization-based security (VBS) requires the use of UEFI firmware. UEFI (Unified Extensible Firmware Interface) is a modern replacement for the older BIOS (Basic Input/Output System) that provides a more secure and flexible booting process, which is essential for features like VBS. VBS relies on the capabilities provided by UEFI to establish a secure memory space and utilize features such as Secure Boot and virtualized security features.

In contrast, Legacy BIOS does not support the modern security features and functionalities that VBS requires. The transition to UEFI enables the system to leverage hardware virtualization and enhanced security mechanisms, which are vital for implementing VBS effectively. Therefore, changing the firmware type from Legacy BIOS to UEFI is a fundamental step necessary to prepare the environment for VBS configuration.
