Pike Research recently released a comprehensive report on the current state and market size of the security business related to global Smart Grid initiatives. This is such a nascent market, you've got to give them credit for even attempting this project. And having seen it, I can say it's a darn good piece of work. You can see Pike's own description and the table of contents HERE as well as register to pay and get a copy. If you want to get a better feel for the experience of the lead author, Bob Lockhart, THIS detailed Q&A on Smart Grid security was just posted yesterday, 8 December 2010.
There's a lot of goodness in the interview, and I like this comment here on getting employees on the right page : One area of security that gets too little attention in smart grids is employee awareness. It is critical for employees of utilities, systems integrators and other involved entities to understand what security is implemented, why it is there, and their responsibilities to support it. This requires a proactive education program. Whether we’re talking e-mails, Web courses, or stand-up instruction matters less than that the points are gotten across to the workforce.
