Cyber war, cyber terror, and cyber crime target all manner of operations and, by design, cannot be detected until they have already done their damage. Nobody is immune to such attacks, and particularly target-rich environments include government bodies and critical power industries such as bulk electricity supply (BES). Hackers and cyberdefenders clash just outside of, at, or inside an organization’s electronic security perimeter (ESP). To counter such threats, a bulk electricity solution — North American Electric Reliability Corp.’s (NERC) Critical Infrastructure Protection (CIP) standards regarding BES cybersecurity — was launched in January 2008 through Federal Energy Regulatory Commission (FERC) oversight. How effective is the use of cyberweapons in protecting electricity’s perimeter?
