摘要: 由于现有网络大多采用被动防御的方式,无法有效抵御复杂环境下黑客恶意攻击,因此,建立一种复杂网络安全主动防御模型。在分析被攻击目标的重要程度和攻击产生的危害后,对攻击策略和防御策略展开分类研究;初始化防御图,并判断其是否为0,分析攻防博弈模型满足条件,根据分析结果的不同计算相对应的攻防成本;判断每一个攻击的目标和意向,为防御图制定相应的最优防御策略。通过开展仿真实验,搭建网络拓扑实例,结果验证该模型可以根据攻击目标和攻击路径确定最优主动防御策略,保证网络信息安全,对自治域内的网络安全防护具有很好的参考价值。

Abstract: Because most of the existing networks adopt passive defense, which can not effectively resist malicious attacks by hackers in complex environments, an active defense model for complex network security under trusted cloud computing is established. After analyzing the importance of the attacked target and the harm caused by the attack, the attack strategy and defense strategy are classified. By initializing the defense map and judging whether it is 0, and analyzing that the attack and defense game model meets the conditions, the corresponding attack and defense cost is calculated according to the different analysis results. By judging the target and intention of each attack, the corresponding optimal defense strategy is formulated for the defense map. By carrying out simulation experiments and building network topology examples, the results verify that the proposed model can determine the optimal active defense strategy according to the attack target and attack path to ensure the security of network information. It is of great value for information security in a autonomous domain.
