System Management Mode deep dive: How SMM isolation hardens the platform
Key to defending the hypervisor, and by extension the rest of the OS, from low-level threats is protecting System Management Mode (SMM), an execution mode in x86-based processors that runs at a higher effective privilege than the hypervisor.
