摘要

提出了一种基于TCM-KNN的网络异常检测新方法

并采用遗传算法选择使用少量高质量的训练样本进行建模

从而有效地对入侵进行检测。大量基于著名的KDD Cup 1999数据集的实验表明:其相对于传统的异常检测方法在保证较高检测率的前提下

有效地降低了误报率;并且

在采用选择后的训练集优化处理后

其性能没有明显的削减

因而相对于传统方法更为适用于现实的网络应用环境。

Abstract

A network anomaly detection scheme based on TCM-KNN algorithm was proposed.Moreover

genetic algo-rithm（GA） based instance selection was introduced to boost the detection performance

meanwhile reduce the computa-tional cost for TCM-KNN.A series of experimental results demonstrate the proposed method is effective

the instance se-lection mechanism also improves TCM-KNN and makes it be a good candidate for anomaly detection in practice.
