Software supply chain focuses on software. How about hardware supply chain security? I refer to Compromise Hardware Supply Chain ("https://attack.mitre.org/techniques/T1195/003/").
I wish to know how can one detect if one's hardware such as CPU, memory chip has been compromised at the hardware level? Are there ways/tools to do so? e.g., perform fuzzing on the hardware layer.
Also, in related to detecting, how does one deter such attacks?
