| > Hardware kill switch - Firewall-level failsafe, not software I think that firewalling/filtering and routing are software (though they can be accelerated in hardware). "Hardware kill switch" is a useful pre-existing term, which I've only seen used to mean a user-controlled mechanical switch that physically opens or closes one or more electrical circuit conductor paths necessary for whatever is to be "killed" (electrically disconnected). For example, let's say your network connector had several pins; a kill switch might mechanically disconnect those pins from wires or PCB traces, in a very simple and verifiable way, which obviously nothing in software/firmware/backdoors/etc. could circumvent. (Well, unless the software could control a robot arm, to go flip the mechanical switch, or solder in a bypass.) Calling something else "hardware kill switch" seems incorrect. I don't say this to be pedantic, but because it's an important security feature, which this system claims to have, but does not. |
