Rethinking the layered security approach

What a recent airport security breach can teach us about how we think of layered security instead of just layered alerts


Back to my thinking on layers of security: I don't believe it's enough to call a simple alert a layer of security, unless that alert and the subsequent response actually is effected in a manner where the response is fast enough to stop the action. If it doesn't create a response fast enough to do that, then I would argue that we are creating "layers of alerts", but not layers of security.

And in the end, we're lucky that this Mr. Duncan was simply trying to catch a free flight, and was not there to perpetrate a malicious act like sabotage a plane or slap an IED onto a wing.
