An old fashioned grid may be inefficient, but it may be easier to secure than a "smart grid". Much of the benefits of a smart grid come from internet connectivity, and that connectivity opens the door to attacks.  (Source: Shuttershock)

Lockheed Martin's General Manager of Energy & Cyber Services, Kenneth Van Meter, speaking with green-power site Smart Planet voiced some dire warnings about the United States' push to adopt a "smart grid".  According to Mr. Van Meter, the transition poses a glaring threat to the security of the U.S.

He comments, "Right now if I wanted to cut off the power to your house, I’d climb the pole, and there’s a manual switch. Everything’s physical. Once we have a smart grid in place I could do that from China."

"The sheer volume of interactive devices on two-way networks is the biggest risk. By the end of 2015 we will have 440 million new hackable points on the grid. Nobody’s equipped to deal with that today."

When asked about the worse case scenario he remarks:

There are three. The one everyone thinks about is the neighborhood kid or someone in another country turning off the power to the neighborhood or the hospital in the middle of night. While no one wants that to happen, it’ll be detected pretty quickly, so it’s not a disaster.

The second potential problem has to do with voltage control. If you want to optimize the amount of power the electrical company has, you want to engage in voltage control, where you have devices along the line from the substation. You can adjust the voltage, everyone gets the right voltage, and everyone’s appliances are running more efficiently. Putting in those devices is expensive, and now those become hackable points–because if you can control them, then someone else can control them. So if your power is out, that would be highly inconvenient. But what if they ran the voltage up and down on your house and when it was fixed, the voltage-sensitive equipment like your computer and high-definition TV didn’t work any more?

Third: If you can cause rapid problems in the grid to occur in the right places at scheduled times, you could destabilize the whole grid, black out whole cities or states and cause massive damage. Sometimes this happens accidentally, but it could also happen because someone makes it happen. Some of the devices are very expensive and therefore there are few spares. Substation-sized transformers, for example, aren’t even made in this country anymore and sometimes it can take two years to get one.

Coincidentally, Mr. Van Meter's company sells security solutions to utilities, so his reason for evangelizing about the smart grid's insecurity may not be purely altruistic.  And Lockheed Martin has had its own security woes recently, with Chinese spies reportedly breaking into servers used in the company's F-35 Lightning II fighter project.

Nonetheless, the points raised are largely valid.  Virtually every large piece of software (Windows, Linux, OS X, Internet Explorer, Safari, Firefox, Adobe Flash, etc.) created has had vulnerabilities that have been found and exploited.  Its unlikely to think that the software that governs the grid will be free of similar vulnerabilities.

A web-connected grid, like Google Grid or Microsoft Hohm, sounds great on paper, but it introduces a pressing need for security, as people from all over the world can now try to attack the power infrastructure remotely.  And where a typical cyberattack may merely deny people access to a website, or damage their personal computers, an attack on the grid could literally prove deadly.  So Lockheed Martin may be a bit biased, but they're probably right, in this case.

Why not combine the two.

Yes, the smart grid poses security threats. But, if you leave the old mechanical protection in place, you can avoid damage to equipment in the event someone takes control. It won't stop someone from turning off the power, but avoids catastrophe. Damaging the grid is the worst possible outcome. Power could be out for weeks or longer. You cannot just get replacements parts and plug them in.
