Humans are the most insecure device attached to computers..
The attack on RSA made me realize that an old joke needs to be updated. The one about "whats the most secure computer" Old Answer: "A computer which is disconnected from the internet, unpowered, buried under 10 feet of concrete." New Answer "A computer which is disconnected from the internet, unpowered, buried under 10 feet of concrete, which no human knows about" Social engineering has always been the week point. But humans have now taken over internet as being the most unreliable piece of equipment connected to the computer.
