Great article featuring Joshua Wright, demonstrating how dependent the coming smart grid is on wireless security, and how far behind the equipment is, despite the fact that the equipment is brand new.
Smart grid? Utility companies have already deployed thousands of 'smart meters' that are vulnerable. It took a wireless security freak (Joshua Wright) to determine that the network devices were not secure. It's all about the people. Devices don't know they are not secure, but you do, if you are properly trained.
