Smart grid security: an oxymoron?

With smart grid security ace Andy Bochman writing for us every week, we cover a lot of ground on the security front, from Stuxnet to the looming challenge of securing volumes of data. In fact, just recently he cautioned utilities to consider the implications of WikiLeaks:

As North American utilities work to achieve and maintain rudimentary security via NERC CIP compliance, implement best practice cyber and physical security controls in IT and OT, and wrestle with how to best combat future threats as powerful as Stuxnet, WikiLeaks lessons should have them question every foundational assumption about what they're seeking to protect, how they're going to protect it, and from whom.

As Andy puts it, nothing prepares you for the thing you didn't see coming.

I'll have more on this topic tomorrow, but for now I'm wondering what YOU think? Can we really make the smart grid secure?
