Trailrunner7 writes "In a column on Threatpost, Bruce Schneier writes that the recent security breach at Newark Airport shows that fixing a given security problem isn't always the right move. 'An unidentified man breached airport security at Newark Airport on Sunday, walking into the secured area through the exit, prompting an evacuation of a terminal and flight delays that continued into the next day. This problem isn't common, but it happens regularly. The result is always the same, and it's not obvious that fixing the problem is the right solution. American airports can do more to secure against this risk, but I'm reasonably sure it's not worth it. We could double the guards to reduce the risk of inattentiveness, and redesign the airports to make this kind of thing less likely, but that's an expensive solution to an already rare problem. As much as I don't like saying it, the smartest thing is probably to live with this occasional but major inconvenience.'"
