Smart grid technologies are introducing millions of new intelligent components to the electric grid that communicate in much more advanced ways (two-way communication, dynamic optimization, and wired and wireless communications) than in the past. Cyber security is important because the bi-directional flow of two-way communication and the control capabilities in the smart grid will enable an array of new functionalities and applications. Two areas of critical importance for the smart grid are cyber security and privacy.
This technical update provides guidance to utilities on developing an overall cyber security strategy, developing a risk management process (including a risk assessment process), and selecting and tailoring cyber security requirements for the electric sector. The National Institute of Standards and Technology Interagency Report (NISTIR) 7628, Guidelines for Smart Grid Cyber Security, is referenced along with other source documents and approaches. The goal is to provide practical guidance to an organization.
