| Firmware: **UEFI firmware version 2.3.1.c or higher with UEFI Secure Boot** | **Requirements**: See the following Windows Hardware Compatibility Program requirement: [System.Fundamentals.Firmware.UEFISecureBoot](http://msdn.microsoft.com/library/windows/hardware/dn932805.aspx#system-fundamentals-firmware-uefisecureboot)
**Security benefits**: UEFI Secure Boot helps ensure that the device boots only authorized code. This can prevent boot kits and root kits from installing and persisting across reboots. |
| Firmware: **Secure firmware update process** | **Requirements**: UEFI firmware must support secure firmware update found under the following Windows Hardware Compatibility Program requirement: [System.Fundamentals.Firmware.UEFISecureBoot](http://msdn.microsoft.com/library/windows/hardware/dn932805.aspx#system-fundamentals-firmware-uefisecureboot).
**Security benefits**: UEFI firmware just like software can have security vulnerabilities that, when found, need to be patched through firmware updates. Patching helps prevent root kits from getting installed. |
| Software: **HVCI compatible drivers** | **Requirements**: See the Windows Hardware Compatibility Program requirements under [Filter.Driver.DeviceGuard.DriverCompatibility](https://msdn.microsoft.com/library/windows/hardware/mt589732(v=vs.85).aspx).
**Security benefits**: [HVCI Compatible](https://blogs.msdn.microsoft.com/windows_hardware_certification/2015/05/22/driver-compatibility-with-device-guard-in-windows-10/) drivers help ensure that VBS can maintain appropriate memory permissions. This increases resistance to bypassing vulnerable kernel drivers and helps ensure that malware cannot run in kernel. Only code verified through code integrity can run in kernel mode. |
