## VBS Key Protection
VBS key protection helps secure Windows keys using virtualization-based security (VBS). VBS uses the virtualization extension capability of the CPU to create an isolated runtime outside of the normal OS. When in use, VBS keys are isolated in a secure process, allowing key operations to occur without ever exposing the private key material outside of this space. At rest, private key material is encrypted by a TPM key which binds VBS keys to the device. Keys protected in this way cannot be dumped from process memory or exported in plain text from a user’s machine, preventing exfiltration attacks by any admin-level attacker.
