摘　　要：针对军事信息网络的防御策略选取问题,分析军事信息网络的攻防对抗特点,提出一种军事信息网络主动防御策略选取方法。该方法基于不完全信息博弈对网络攻防过程进行建模,从网络安全属性的角度出发对攻防收益进行量化;以防御效能作为策略选取的标准,设计主动防御策略选取算法。与传统基于博弈论的网络防御方法相比,该方法具有如下优势:在模型设计和收益量化方面更加符合网络攻防实际;能够以纯策略的形式进行主动防御策略选取,有效解决当前以概率形式进行防御策略选取不便于理解和操作的问题。通过实验验证了所提方法的合理性和可行性,并通过防御收益分析总结了网络安全防御的一般规律。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.
