![]() Virtualization-based security protects your secrets against Malware running in the operating system with administrative privileges.Better protection against advanced persistent threats: Securing derived domain credentials using the virtualization-based security blocks the credential theft attack techniques and tools that are used in many targeted attacks.Hardware security: Credential Guard increases the security of derived domain credentials by taking advantage of platform security features including, Secure Boot and virtualization.(Boot order, Boot entries, Secure Boot, Virtualization extensions, IOMMU, Microsoft UEFI CA.) UEFI firmware version 2.3.1 or higher: UEFI is locked down, so that the settings in UEFI cannot be changed to compromise Device Guard security. Dell has verified select Precision, Latitude, and OptiPlex computers that must have updated BIOS and HVCI-compliant drivers. Virtualization-Based Security features of Windows 10 Enterprise/Education leverage a range of security elements like UEFI, Secure Boot, Trusted Platform Module (TPM) 2.0. Device Guard depends on Virtualization based security (VBS). So that the device can only run trusted applications that are defined in your code integrity policies. You can configure it to lock a device down. If it is not a trusted application, it cannot run. When they are configured together, they lock a device down so that it can only run trusted applications. Credential Guard is not dependent on Device Guard.ĭevice Guard is a combination of enterprise-related hardware and software security features. ![]() Credential Guard uses virtualization-based security to isolate secrets so that only privileged system software can access them. Credential Guard prevents these attacks by protecting NT LAN Manager protocol (NTLM) password hashes and Kerberos Ticket Granting Tickets. ![]() Unauthorized access to these secrets can lead to credential theft attacks. It is only available to computers covered by a Microsoft Volume License Agreement (VLA).Ĭredential Guard uses virtualization-based security to isolate secrets (credentials) so that only privileged system software can access them. With Local Security Authority (LSA) functions using Hypervisor Code Integrity (HVCI) drivers and a compliant BIOS with the Windows 10 Enterprise/Education Edition operating system. What is Device Guard and Credential Guard?ĭevice Guard and Credential Guard are Virtualization-based security (VBS). Summary: "Overview of two new Windows 10 Enterprise Ready Security features: Credential Guard and Device Guard."
