为实现目标网络的适度安全,提出了一种基于最优攻击路径的网络安全增强策略制定方法。该方法对攻击目标进行风险评估,在分析攻击图最优攻击路径的基础上制定安全增强策略。为了获取最优攻击路径,提出了一种基于蚁群优化算法的最优攻击路径生成方法,并改进了信息素更新方式。仿真实验表明,所提方法能够有效地产生安全策略集,改进后的蚁群算法具有较强的全局搜索能力和更好的收敛性。

To reach the proportional security of the goal network,an approach on network security enhancement strategies based on optimal attack path was proposed.The approach assesses the risk of attack target,and makes strategies for network security enhancement on the basis of optimal attack path.To obtain optimal attack path,an approach to generating optimal attack path based on ant colony optimization algorithm was proposed,and the pheromone updating way was improved.Simulation results show that the proposed approach can generate strategies effectively,and the improved ant colony optimization algorithm has strong global search ability and rapid convergence.
