Research and Design of Security Defense Model in Power Grid Enterprise Information System

Because of the special position of electric power industry in national economy and social life, electric power information security has been given particular attention. With the development of electric power informationization, the threat of information security has become more and more serious. Risks and losses, caused by potential safety hazard in electric power enterprise information system, have become more and more serious. The special nature of electric power enterprise information system security has particular requirements for information security defense system. In order to meet the special requirements of electric power enterprise information systems security, the concept of network business security has been proposed, constructing security defense system from the two levels of data security and network business security. According to the specific situation of power grid enterprise information system´s businesses, classification and protection methods for power grid enterprise information system have been proposed. What´s more, on the basis of the classification and protection methods, security defense model of power grid enterprise information system has been designed, providing a theoretical basis for the security construction of power grid enterprise information system.
