基于概率推理的入侵意图识别研究

攻击者的入侵行为背后往往蕴含着攻击者的目标和意图,据此提出了入侵意图识别的层次化模型。为了处理网络环境中的不确定性信息,提出了基于概率推理的入侵意图识别算法,并在此基础上预测攻击者的后续攻击规划和目标,从而起到提前预警的作用。根据网络安全事件、目标和意图之间的因果关系建立的贝叶斯网络能够描述和处理并发意图识别问题。试验证明了该方法的可行性和有效性。

Study on Intrusion Intention Recognition Based on the Probabilistic Inference

Intrusive behaviors of attackers always imply their objects and intentions,hereby a hierarchical model of intrusion intention recognition was proposed.In order to handle the uncertain message in the circumstance of computer networks,intrusion intention recognition algorithm based on probabilistic inference was presented.On this basis the future plans and goals of the attackers can be predicted in order to take actions in advance.Bayesian networks were constructed to cope with the concurrent intention recogn...
