Clearly, Answer is More Money to the NSA Contractors for Cyberdefense

Did you hear about the attack on a power plant in California?

No, it was not a cyber attack, it was guys with guns:

When U.S. officials warn about "attacks" on electric power facilities these days, the first thing that comes to mind is probably a computer hacker trying to shut the lights off in a city with malware. But a more traditional attack on a power station in California has U.S. officials puzzled and worried about the physical security of the the electrical grid--from attackers who come in with guns blazing.

Around 1:00 AM on April 16, at least one individual (possibly two) entered two different manholes at the PG&E Metcalf power substation, southeast of San Jose, and cut fiber cables in the area around the substation. That knocked out some local 911 services, landline service to the substation, and cell phone service in the area, a senior U.S. intelligence official told Foreign Policy. The intruder(s) then fired more than 100 rounds from what two officials described as a high-powered rifle at several transformers in the facility. Ten transformers were damaged in one area of the facility, and three transformer banks -- or groups of transformers -- were hit in another, according to a PG&E spokesman.

"These were not amateurs taking potshots," Mark Johnson, a former vice president for transmission operations at PG&E, said last month at a conference on grid security held in Philadelphia. "My personal view is that this was a dress rehearsal" for future attacks.

I am inclined to agree with Mr. Johnson.

We've spent billions on cyber defense for an attack on the grid which has never occurred, anywhere in the world, but physical attacks on power stations by insurgents have been occurring since power plants first existed.

Of course, it's not the current business model for the for-profit portion of out state security apparatus, so not a whole bunch of money there.
