Network Attack Model and Security Strategy Optimization Based on Defense System

Abstract

Recently, the situation of network security is becoming more and more serious, and the attacks on key information systems are more frequent. Predicting attackers and attack behavior accurately and efficiently is the key to ensure system network security. In our work, the company's cloud firewall (FW), Intranet firewall and situational awareness (SA) system were used to collect and analyze the data of overseas attacks on the company's key information system in the recent quarter. Furthermore, we first establish a mathematical model of the network attack based on the dynamic theory. It is fantastic that the theory fits in well with the practice so that we can employ the model created by the oscillation theory to forecast the circumstance precisely. In particular, we optimize the security strategy correspondingly to make the number of overseas attacks converge tremendously and achieve efficient blocking, when the production and operation of the enterprise keep undertaking ordinarily with little error banning.
