After an attack occurs in the network,the privacy of user information and related service information may be leaked and stolen.Therefore,an actual attack and defense strategy of network security based on game theory is studied.Based on the interaction between attacker and defender,the strategy builds a three-layer Stackelberg competitive game model for network se-curity protection.In the first layer,the attacker behavior is modeled based on the preference,so as to analyze the probability of attacker's target selection.Stackelberg game strong equilibrium strategy algorithm is used to solve the optimal strategy of net-work security.The test results show that strategies can effectively defense against network vulnerability attacks,and ensure network security.
