Research on the network security risk control based on game model

This paper provides an optimization trade-off algorithm to study the control of network security risk, and provides a guidance method for network security control. The game model is used to establish the game model of the attacker and the defender in the network security. Based on this model, the optimal risk control strategy generation algorithm is proposed to find the optimal risk control strategy to avoid the network administrator's blindness in the network security risk control Investment, reduce the enterprise in the network security risk control on the loss. The algorithm model is suitable for the network security risk assessment, and the empirical analysis is carried out for the network security. The result shows that the model can get the better scheme, in the state (MS SQL Server, User) and (Mail Server, User), we can get the maximum utility.
