saturday afternoon defcon 13

Mark Tobias and his security.org crew had an interesting discussion about full disclosure for physical security devices e.g. locks and safes. So a number of vulnerabilities were discussed. All were well known. The main question was asked, "Does it increase security of locks to disclose defects"? Of course the answer was yes. but it was actulaly pointed out the both kryptonite and best locks are now made without previou defects found.

Following that was another talk on lockpicking. Perhaps the most important demonstration was the one showing a defect in common gun locks. These can be breached in about 5 seconds by anyone with a wire. Kind of chilling.

Got some pizza and water for lunch.
