The design of information security protection framework to support Smart Grid

With the unified and strong smart grid construction by State Grid Corporation of China, information security protection architecture is facing new challenges. The characteristics of smart grid such as informationization, automation, and interaction, have enhanced the two-way interaction between grid and consumers. The design method of information security protection architecture in U.S. Smart Grid and new information security protection requirements of China Smart Gird and new information security risks were proposed and analyzed. An information security protection model and overall information security protection strategy were proposed considering the characteristics of China Smart Grid and the new information security protection requirements. Based on this model, the information security protection framework was designed to support the information security protection in smart grid. The proposed framework consists of four parts: security governance, security management, security maintenance, security technology. Finally, a methodology for the implementation of information security protection framework was given, which guides the business systems in every aspect of smart grid to implement information security protection works from the points of technology, management, and operation.
