An interesting report on not-quite high-security locks, as demonstrated at DefCon this year. Most people are surprised at just easily a common padlock can be bypassed (even I can pick a Master padlock without too much difficulty), and even more, I imagine, will be surprised to discover that some “high security” locks aren’t a whole lot better.
It’s a moot point, really. People attack weak security points, whatever they might be. You don’t pick the lock on a gate whose fence you can easily climb over; you don’t pick a door lock when you can jimmy a window lock instead, or enter through an unlocked loading-dock door. A determined adversary isn’t going to be stopped just because you put shiny, expensive locks on your door…
