Executive Summary

There is no debate about the potential advantages that a smart grid can bring. The ability to bring together complex, proprietary systems onto a common, standards-based network infrastructure will enhance communications, improve efficiency, help reduce costs, integrate renewable sources of energy, and promote more opportunities for innovation. The fallacy is that a smart grid is less secure: that by migrating the energy network to IP, it is exposing critical infrastructure to the dangers of the Internet. The reality is that using IP as a communications protocol is not the same as putting the energy grid on the Internet. In fact, because experience and history in how to secure IP networks already exist, the energy industry can effectively use this knowledge.
