The nation’s power system consists of both legacy and next generation technologies. New grid technologies are introducing millions of novel, intelligent components to the electric grid that communicate in much more advanced ways than in the past: two-way communications, dynamic optimization, and wired and wireless communications. Cyber security is important because the bi-directional flow of two-way communication and control capabilities in the smart grid will enable an array of new functionalities and applications and with them will come new vulnerabilities.
This technical update provides guidance to utilities on developing and implementing a risk assessment process using the failure scenarios developed by the National Electric Sector Cybersecurity Organization Resource (NESCOR) program. NESCOR is a Department of Energy (DOE) funded public-private partnership led by EPRI.
