What is Virtualization-Based Security (VBS) and how does it work?
Virtualization-Based Security (VBS) is a Windows 10 and 11 feature that uses hardware virtualization to create a secure environment for sensitive operations. It works by leveraging the capabilities of the CPU to create a virtualized environment, known as a virtual secure mode (VSM), which is isolated from the rest of the system. This environment is used to run sensitive code, such as Windows Defender Advanced Threat Protection (ATP) and Windows Credential Guard, in a secure and isolated manner.
The VSM is created using the CPU’s virtualization extensions, which allow the operating system to create a virtual machine (VM) that is isolated from the rest of the system. The VSM is then used to run sensitive code, which is loaded into the VM and executed in a secure environment. This provides an additional layer of protection against malware and other types of attacks, as the sensitive code is isolated from the rest of the system and cannot be accessed by malicious code.
How do I check if my PC has VBS enabled?
To check if VBS is enabled on your PC, you can use the System Information tool in Windows. To do this, press the Windows key + R to open the Run dialog box, type “msinfo32” and press Enter. This will open the System Information tool, which will display information about your system, including whether VBS is enabled. Look for the “Virtualization-based security” section, which will indicate whether VBS is enabled or disabled.
Alternatively, you can also use the Windows PowerShell to check if VBS is enabled. To do this, open PowerShell as an administrator and run the command “Get-ComputerInfo -Property “VirtualizationBasedSecurity*””. This will display information about VBS, including whether it is enabled or disabled. If VBS is enabled, the output will indicate that it is running, and you will see information about the virtual secure mode (VSM) and the sensitive code that is running in it.
What are the system requirements for VBS?
To enable VBS on your PC, your system must meet certain requirements. These include a 64-bit version of Windows 10 or 11, a CPU that supports virtualization (such as Intel VT-x or AMD-V), and a Trusted Platform Module (TPM) 2.0 chip. Additionally, Secure Boot must be enabled and set to UEFI mode, and the CPU must support Second Level Address Translation (SLAT).
If your system meets these requirements, you can enable VBS by going to the Windows Settings app, clicking on “Update & Security”, and then clicking on “Windows Security”. From there, click on “Device security” and then click on “Core isolation details”. If VBS is supported on your system, you will see an option to enable it. Note that VBS may not be compatible with all systems, so you may need to check your system specifications to determine if it is supported.
