Research of Online Evaluation Model and Algorithm for Network Attack Effect
网络攻击效果在线评估模型与算法研究

In order to achieving the network attack object perfectly,it's very importantto evaluating the attack effect in real time and making proper attack strategy.The relationship between attack effect and network security property is analyzed.A definition of the network attack effect based on the change of network security property is given.The online evaluation model and evaluation algorithm for network attack effect are mainly studied in this paper.The evaluation rule and evaluation metrics are brought forward.The framework and design method of the network attack effect online evaluation system are described.The evaluation algorithm,attack status graph generating algorithm,attack effect predicting algorithm and attack scenario decision-making algorithm are discussed carefully.Finally,some problems which should be researched thoroughly in the future are pointed out.
