The honest answer is that we don’t know yet. It’s hugely complex and very different than IT security. http://bit.ly/7a2oTp
This is a great article by the Smart Grid Security Blog on how traditional IP security needs to be reinvented for the Smart Grid.
The evolution of the Smart Grid, and most notably the introduction and expansion of IP-based internetworking into the traditionally SCADA, and often proprietary, world of utilities is bringing a new series of threats to the Grid, as we have been writing about for some time now. Much of our blogging in the past year has focused on it: on the threats, on the similarities, and on the insufficient attention we believe the problem has received. Read more => http://bit.ly/6nkYWj

Having done it the hard way (learning from our own mistakes), we highly recommend the easy way (learning from the mistakes of others). In that regard, the telecommunications industry may be one of the best places to look for best practices in how utilities can use the Smart Grid’s real-time information from millions of devices like smart meters. By mimicking what telecommunications does today to manage peak loads and help with low credit score customers, we can leap past decades of learning experiences. Read more => http://bit.ly/8pzJ95
The latest draft of the NIST report includes very good news: the addition of IPv4 and IPv6, and the addition of ITU G.hn (communications over power lines and other wire types) to the list of “standards identified for implementation” for Smart Grid.
