About ten years too late

DARPA tasks BAE with workaround to secure the power grid in event of massive attack
The Defense Advanced Research Project Agency and BAE Systems are working to forge alternative communication networks that would come into use in case of a cyberattack on the U.S. electrical power grid.

Although the aim is to ensure safe connectivity among all of the civilian nodes which depend upon the power grid, the program is particularly focused on securing defense networks and operational combat activities.

The program, called Rapid Attack Detection, Isolation and Characterization Systems (RADICS), consists of a variety of technical capabilities. These include an ability to recognize or provide early warning of impending attacks, map conventional and industrial control systems networks, ad hoc network formation and analysis of control systems, a DARPA statement said.

It is one thing to come up with an idea and a cool acronym. Another thing entirely to actually implement it in an effective way. They should have been thinking about this ten or twenty years ago. North Korea has a satellite in a ball of string orbit which covers the USA every couple of days. There is a reason why the world banned atmospheric testing back in the 1960's
