Secure Kernel Code Integrity
Microsoft Corporation - FIPS 140 #4640
Secure Kernel Code Integrity (SKCI) running in the Virtual Secure Mode (VSM) of the Hyper-V hypervisor will only grant execute access to physical pages in the kernel that have been successfully verified. Executable pages will not have write permission outside of Hyper-V. Therefore, only verified code can be executed.
