The weakest link is the user!
As if we didn’t already know it, where security is concerned, the user is the flaw. Guido has published the perfect example:
Everyone has to carry around not only their government communications network issued Blackberry phone, but a Blackberry Smart Card Reader too, with another SIM card in it. If the two are separated by more than ten metres or so the Blackberry stops working. So if a pickpocket stole the Blackberry, it would stop working. Carrying two units is a little cumbersome and inconvenient. Unfortunately from a security point of view, the wonks and spinners have taken to just sello-taping the two of them back to back…
