Op ed piece in the Wall St Journal, decrying to failure of the government to "protect the electric grid" from hostile Chinese hackers.
Sorry, it is the responsibility of the power companies to protect their assets, not the government. All that is necessary is to make sure that control of generators and other machinery never goes over the public internet, and that Windows computers are never connected to the internet. They can even use cheap PC's so long as they run Linux and not Windows.
State public utility commissions should be asking their regulated power companies about use of the public internet.
