Processor microarchitecture security
- {Instructor] In addition to securing an applications code and infrastructure, you can extend your security efforts all the way down to the CPU. In order to do that though, you need to know a little bit about processor micro architecture security extensions. Processor micro architecture security extensions. That's quite a mouthful, isn't it? Let's break it down to make it a little easier to digest. A computer's processor includes an instruction set that tells the processor how to interact with the computer's hardware. This instruction set varies depending on who manufactured the processor. In addition to those basic instructions, manufacturers have added some specific codes to protect those CPUs from hardware-based attacks. We call those codes security extensions.
