Research On The Architecture And Key Technology Of Information Security Defense System In Smart Grid

Power information network has become an important part of the production, management and development of the electric power industry. With the State Grid Corporation of "building a strong smart grid", "three big five" proposed, resulting in increasing of enterprise application system surge and external interface, may face from both internal and external malicious attacks more and more, the smart grid information security faces great challenges. Therefore, to strengthen the safety management of electric power information network becomes more and more important. To solve the smart grid faces the problem of information security, this paper introduces in detail the smart grid theory and smart grid information security related knowledge, insight into the smart grid information security is facing security threats. And through the in-depth study of information security and the existing passive defense technology of active defense technology, combined with the advantages and disadvantages of two kinds of defense system, put forward a kind of passive defense system. The system is combined by the active defense system and the passive defense system, which the passive defense system based on the level of protection from the boundary, network, server, application and several data protection, active defense system from the three dimensions of security technology, security policy, security management into protection, combination of active and passive, adequate protection of the information security of smart grid.
