You have spent lots of money on a highgrade, pickresistant, ANSIrated lock for your door. Your vendor has assured you how it will resist attack and how difficult it would be for someone to copy your key. Maybe they’re right. But… the bulk of attacks that both penetration testers and also criminals attempt against doors have little or nothing to do with the lock itself! This talk will be a hardhitting exploration (full of photo and video examples) of the ways in which your door — the most fundamental part of your physical security — can possibly be thwarted by someone attempting illicit entry. The scary problems will be immediately followed by simple solutions that are instantly implementable and usually very withinbudget. You, too, can have a nearperfect door… if you’re willing to learn and understand the problems that all doors tend to have.
