Cute, but a lot of people seem to be wondering this, so a better answer is deserved. The ATM machine is somewhat protected for the extremely obvious reason that it has cash in it, but an ATM is hardly impervious. http://www.youtube.com/watch?v=4P8WM8ZZDHk There are all sorts of strategies for attacking ATM's, and being susceptible to a sledgehammer, crowbar, or truck smashing into the unit shouldn't be hard to understand. Most data centers have security that is designed to keep honest people out of places that they shouldn't be. Think that "security guard" at the front will stop someone from running off with something valuable? Maybe. Have you considered following the emergency fire exits instead? Running out the loading dock? Etc? Physical security is extremely difficult, and defending against a determined, knowledgeable, and appropriately resourced attacker out to get *you* is a losing battle, every time. Think about a door. You can close your bathroom door and set the privacy lock, but any adult with a solid shoulder can break that door, or with a pin (or flathead or whatever your particular knob uses) can stick it in and trigger the unlock. Your front door is more solid, but if it's wood, and not reinforced, I'll give my steel-toed boots better than even odds against it. What? You have a commercial hollow steel door? Ok, that beats all of that, let me go get my big crowbar, a little bending will let me win. Something more solid? Ram it with a truck. You got a freakin' bank vault door? Explosives, torches, etc. Fort Knox? Bring a large enough army, you'll still get in. Notice a pattern? For any given level of protection, countermeasures are available. Your house is best "secured" by making changes that make it appear ordinary and non-attractive. That means that a burglar is going to look at your house, say "nah," and move on to your neighbor's house, where your neighbor left the garage open. But if I were a burglar and I really wanted in your house? There's not that much you could really do to stop me. It's just a matter of how well prepared I am, how well I plan. So. Now. Fiber. Here's the thing, now. First off, there usually isn't a financial motivation to attack fiber optic infrastructure. ATM's get some protection because without locks, criminals would just open them and take the cash. Having locks doesn't stop that, it just makes it harder. However, the financial incentive for attacking a fiber line is low. Glass is cheap. We see attacks against copper because copper is valuable, and yet we cannot realistically guard the zillions of miles of copper that is all around. Next. Repair crews need to be able to access the manholes. This is a multifaceted problem. First off, since there are so many manholes to protect, and there are so many crews who might potentially need to access them, you're probably stuck with a "standardized key" approach if you want to lock them. While this offers some protection against the average person gaining unauthorized access, it does nothing to prevent "inside job" attacks (and I'll note that this looks suspiciously like an "inside job" of some sort). Further, any locking mechanism can make it more difficult to gain access when you really need access; some manholes are not opened for years or even decades at a time. What happens when the locks are rusted shut? Is the mechanism weak enough that it can be forced open, or is it tolerable to have to wait extra hours while a crew finds a way to open it? Speaking of that, a manhole cover is typically protecting some hole, accessway, or vault that's made out of concrete. Are you going to protect the concrete too? If not, what prevents me from simply breaking away the concrete around the manhole cover rim (admittedly a lot of work) and just discarding the whole thing? Wait. I just want to *break* the cable? Screw all that. Get me a backhoe. I'll just eyeball the direction I think the cable's going, and start digging until I snag something. Start to see the problems? I'm not saying that security is a bad thing, just a tricky thing. ... JG -- Joe Greco - sol.net Network Services - Milwaukee, WI - http://www.sol.net "We call it the 'one bite at the apple' rule.
