Abstract: The characteristics of attack-defense confrontation behavior of military information network are analyzed for its defense strategy of military information network, and a method for selecting an active defense strategy is proposed. A network attack-defense game model is constructed based on incomplete information game. And the attack-defense payoffs are quantified from the perspective of network security attributes. An active defense strategy selection algorithm is proposed by taking the defense effectiveness as the criterion of strategy selection. Compared with the classical network defense method based on game theory, the proposed method is more suitale for network attack and defense practice in model design and payoff quantification. At the same time, the active defence strategy can be selected in the form of pure strategy, which is easier to understand and operate than the current optimal strategy selection in the form of probability. The rationality and feasibility of the proposed method are verified through a representative experiment, and the general rules of network defense are summarized through the analysis of defense payoffs.Key
