基于攻击路径图的网络攻击意图识别技术研究

摘要

The current network attack analysis and threat assessment are based on the static network environment and at⁃tack behaviour. For this problem,the network attack intention dynamic recognition system was designed. The attack intention preventing algorithm based on minimum vertex cut and attack intention dynamic recognition algorithm based on timed automata are studied. The framework of the network attack intention dynamic recognition system was established,and the system design was accomplished. The system was tested on the constructed temporary experiment network platform. The experimental results show that the network attack intention dynamic recognition system is effective in test environment.%针对目前网络攻击分析和威胁评估都是建立在静态的网络环境和攻击行为之上的问题，设计了网络攻击意图动态识别系统。研究了基于最小顶点割的攻击意图阻止算法和基于时间自动机的攻击意图动态识别算法，搭建了网络攻击意图动态识别系统的框架并完成了该系统的设计。最后搭建了临时实验网络平台进行实验，实验结果表明，网络攻击意图动态识别系统在测试环境下是正确有效的。
