We’re all doomed! Scary, right? Well, maybe, but I should explain a bit first.
Back in the dark ages of computing, say 2011, Microsoft announced they would implement Secure Boot, which is a protocol included in the UEFI, Unified Extensible Firmware Interface(BIOS successor), in Windows 8 – which had not been implemented previously.
The purpose of Secure Boot is to ensure that the software, or operating system, being loaded on a computer is genuine, unchanged, and secure. In short, it’s forms a chain of trust from the moment you power on your computer until the OS is loaded while preventing root kits, boot kits, and other nefarious software from infecting your computer.
