The smart grid and the Internet of things is going to provide for a more efficient operation of infrastructure and everything else that's now web-enabled to provide for more effective management of these systems, but the connectivity of these things to the web provides a potential means of attack to adversaries. Security needs to be baked into these investments in efficiency and effectiveness, baked into this development of connectivity to the web rather than tacked on after a successful attack occurs.
