Same reason you lock your front door despite the landlord having a spare key, or the lock maker having a master key. You're screwed if the landlord or a rouge lock maker employee want to get into your place -- but it's good protection against everything else.
- emn13 11y agoPhysicals locks are poor analogies for encryption. A physical lock isn't designed to provide robust security - it's trivially easy to open almost any lock - it's to make opening it a noisy, slow, dangerous and expensive affair. And even if you have that magical perfect physical lock, few houses (or other containers) are impregnable. A physical lock is more like an effective intrusion detection system - it's not going to prevent hacks, but it might make those that have something to lose think twice, and at least you're likely to know if you've been robbed. Just like intrusion detection, physical locks make it at least somewhat risky to even try to break in - after all, you might get caught.
- nickpsecurity 11y agoExactly what you said whether people like the lock analogy or not. I used to encourage the use of high assurance security that comes from defense sector. People said "but they might be backdoored by NSA!" I said, "Maybe but they'll protect you from all the other threats which are doing the real damage here. You can always layer something foreign in there if you want to give NSA headaches." Same concept.
