UEFI is a technology that forces a computer to only load a digitally signed operating system. This has some security benefits, as it makes parts of the operating system unbootable if they become infected, since the viruses won’t be digitally signed by a reputable vendor.
Great idea, right? From a security perspective, absolutely. The more attack vectors for viruses we can eliminate, the better off we’ll be. But Microsoft’s policy on ARM systems shows how it can be abused.
