I had a discussion with a senior utility person involved with Smart Grid. He told me about all of his cyber experts (he did not consider me a cyber security expert), many of which are very good at hacking/crashing systems. However, he had very few “experts” on the systems they are trying to protect. The intent of control system cyber security is not to hack these cyber vulnerable systems but to protect them. Wouldn’t it make sense to also have experts on the systems you are trying to protect?

If all one had to draw from was the flood of conferences, webinars, and advertisements, it would appear that the Smart Grid is a very recent invention that will be installed en-masse in the near future. In reality, elements of the Smart Grid first appeared in the 1998-2000 time-frame. Additionally, legacy devices will continue to be used in the “Smart Grid” for at least the next 5-10 years. Until about 6-8 months ago, domain knowledge was a given for those participating in the “Smart Grid”. Now, domain knowledge doesn’t seem to be a requirement.
