Security is an illusion. It's not a boolean state--on or off, secure or insecure. It's relative. Relative to the value of the thing(s) you're trying to protect, but also relative to the security around you. Kind of like two men with a bear chasing them, I don't have to make my house the most secure house around, it just has to be more secure than my neighbors'.
As I said before, I am a security expert. Information security, but still. I've used bump keys. There's video of 12-year-old girls using bump keys successfully. And then there's the lockpicking "obstacle course" at one con, where teens and youngsters compete at opening the most different kinds of locks in the shortest overall time.
So this is where my conundrum comes... I have been wanting a set of good, bump-proof locks for my house. And then I find Z-Wave-based door locks. Two brands--Schlage and Kwikset. I haven't investigated them very well yet, but I know that Kwikset has no bump-proof locks, at last check. I know Schlage does, but not across their entire line.
So I'm torn... do I defend against the unlikely, but class-breaking bump key? Or do I go for the ease and peace-of-mind that comes with being able to automatically lock my whole house down whenever I leave?
