Comprehensive Cybersecurity for Critical Infrastructure
The electrical power generation and distribution industries, especially here in the U.S., have a long history in working to improve reliability and security. This history goes back to the establishment of the North American Electric Reliability Council (NERC) in the late 1960s as a response to a widespread blackout in the Northeastern U.S. NERC became the North American Electric Reliability Corporation (also NERC)...
