| 摘 要： | 介绍了网络蠕虫的定义和工作机制,通过分析得到了网络蠕虫的共有特性.根据蠕虫的特性,提出了一个基于贝叶斯的网络蠕虫检测方法,采用贝叶斯公式来计算首次连接失败的概率,对于不能确定的情况,用后验概率更新先验概率.设计了一个基于贝叶斯的网络蠕虫检测系统的原型系统,详细描述了该系统的结构模型,并从功能角度上介绍了该系统的两个主要组成部分.

| Abstract: | The definition and mechanism of Internet worms is introduced,and the characteristic of the Internet worm is analyzed.Ac-cording to the Internet worm's characteristic,an Internet worm detection method based on Bayesian is proposed.Uses Bayesian formula to calculate the defeat first contact connect probability.Regarding indefinite situation,it uses the posterior probability to renew the prior probability.An Internet worm detection prototype system based on Bayesian method is designed.The structure of this sys... |
