Open Turn on Virtualization Based Security and choose Enabled (radio button). Virtualization based protection of code integrity enforces kernel mode memory protections as well as protecting Code Integrity validation paths. Comprehensive protection without the implementation challenges. In Windows 10, Microsoft introduced virtualization-based security (VBS), the set of security solutions Credential Guard with armor key protection and smartcard-based authentication As described in [sop], it is possible to configure an account so that it can authenticate only from a VBS-enforced code integrity. Enable virtualization-based protection of code integrity. The below-OS implementation [5, 9, 17, 38] of security solutions was a logical consequence of the large-scale adoption of virtualization used to run more virtual machines (VM) on the same physical system. Group Policy - centrally enable and configure virtualization based security settings on endpoints, deploy Catalog files and Code Integrity policies. The security tools in such cases are based on the control capabilities of the virtualization system, usually called hypervisor or VM monitor (VMM).
