| 摘 要： | 提出一种基于贝叶斯理论的入侵检测系统(IDS)评测方
法, 设计并建立了一套较完善的入侵检测系统评测体系. 确立了用于评测IDS的4个重要指标：功能指标、 性能指标、 安全性指标和用户可用性指标. 量化分析了一些主要测试指标, 并利用概率树模拟入侵及检测过程. 结果表明, 该方法能在系统的检测率和误报率间找到最佳的阈值平衡点.

| Abstract: | A fresh IDS evaluation method based on Bayesian theory was proposed,and a more perfect Intrusion Detection System Evaluation System was thus designed and constructed.Meanwhile,the four important indices to evaluate IDS,that is,function index,performance index,security index and user availability index,were established.The specific quantitative analysis about some of the major indices was made,moreover,the process of intrusion and detection was simulated with probability tree.The results show that the presen... |
