No, that is not a stupid question. I don't see the threat level is so sophisticated that you have to worry about them discovering the hole in your force protection. This is a simple force on force exercise. If your security makes them pay a high price, they will look elsewhere. Not only would I beef up my security, I would make sure that everyone knows how strong it is and how futile it would be to challenge that security. The opponents are not "Mission Impossible" kind of people sneaking through the air vents with their computer over ride codes.
