An Method of Active Deception Defense for New Power System

With the construction and development of new power system, the security risks of the power grid information system are becoming increasingly severe. This paper first introduces the current situation of information asymmetry in network attack and defense. Traditional network security protection can only be passive defense and can only deal with known network attack methods. Therefore, the idea of active deception defense is proposed. Secondly, the main technical routes for active deception defense are introduced, and the advantages and disadvantages of different technical routes are elaborated. Finally, based on the characteristics of the new power system, a theory of active deception defense based on game model is proposed, and Nash equilibrium is used to solve the optimal defense strategy, achieving maximum benefits.
