I guess hardware security refers to the security of it's firmware, but the firmware is just software, so why do we call it hardware security?
If I am wrong, can anyone explain what is hardware security? If there is no code, how could vulnerabilities exist?
Is finding bugs in a router's firmware or in computer's BIOS considered as hardware hack?
Is this Hacker News report about Intel server chips considered as hardware hack? Do those chips have firmware? Which computer hardware parts have firmware and which haven't?
