| 摘 要： | 将贝叶斯(Bayes)方法用于一种动态线性模型,即贝叶斯动态模型,再将此模型应用于网络安全的代理分布式的入侵检测系统,预测用户行为,这样的系统就能确定用户是在进行不可预测行为,还是已经改变了他的正常工作方式,从而对组织内部的攻击起防范作用。

| Abstract: | This paper presents a novel application of the Bayesian technique which can be applied for DLM,namely Bayesian DLM,and again it be applied to distributed-based Intrusion Detection System for enhanced network security by trying to predict user actions.In this way the system can determine if a user is acting unpredictably or has changed his normal working pattern.So it can guard against attacks inside the organization. |
