What is Virtualization-Based Security (VBS)

The Internet provides rapid information access but also serves as a breeding ground for cyber threats. With the rise of sophisticated threats, safeguarding computer systems has become more important than ever. One advanced security feature designed to enhance protection is Virtualization-Based Security (VBS).

Leveraging hardware virtualization, VBS creates a more resilient and secure computing environment.​

What is Virtualization-Based Security (VBS)?

Virtualization-Based Security (VBS) is a security technology that uses hardware virtualization and the Windows hypervisor to create an isolated, secure environment within the system. This virtual space acts as a trusted foundation for the operating system, protecting critical components from threats such as malware and unauthorized access. By maintaining a separate, secure execution area, VBS ensures that even if the main OS is compromised, sensitive processes remain protected.

Hypervisor Types

A hypervisor is a software layer that enables the creation and management of virtual machines (VMs) by abstracting hardware resources. There are two primary types of hypervisors:​

Type 1 Hypervisors

Also known as bare-metal hypervisors, Type 1 hypervisors run directly on the host’s hardware, controlling the physical resources and managing guest operating systems. They are renowned for their efficiency and are commonly employed in enterprise environments. Examples include VMware ESXi, Microsoft Hyper-V, and Xen.

Type 2 Hypervisors

Referred to as hosted hypervisors, Type 2 hypervisors operate atop a conventional operating system, functioning like any other software application. While they offer flexibility and ease of use, they may introduce additional latency due to their reliance on the host OS. Popular examples are VMware Workstation and Oracle VirtualBox. ​

What is Virtualization-Based Security in Windows?

In Windows, VBS takes advantage of the Windows hypervisor to create a protected memory environment, isolating sensitive processes from potential attacks. This technology supports advanced security features such as Credential Guard and Hypervisor-Enforced Code Integrity (HVCI).

• Credential Guard protects user credentials by keeping them separate from the rest of the operating system, preventing attackers from extracting login information.
• HVCI ensures that only trusted and digitally signed drivers and applications can run, blocking malicious software from executing.

By implementing VBS, Windows significantly enhances its security posture, making it more resistant to modern cyber threats.
