摘    要
入侵检测技术是对传统的安全技术（如防火墙）的合理补充。它通过监视主机系统或网络，能够对恶意或危害计算机资源的行为进行识别和响应。通过与其它的安全产品的联动，还可以实现对入侵的有效阻止。入侵检测系统的研究和实现已经成为当前网络安全的重要课题。
本文从研究入侵技术入手，分析了入侵过程的各个阶段、各种入侵方法，总结了网络安全事故的根源。然后，介绍了入侵检测方法的分类，分析了各种入侵检测方法和字符串匹配的算法。研究表明基于规则的入侵检测系统是现在入侵检测系统设计的最主要的技术，基于这一理论，设计开发了一个基于规则匹配的特征检测方法的响应模块。系统开发环境为VC++ 6.0，数据库采用MYSQL数据库。通过该系统可以有效的实现对入侵的检测，并且具有用户友好性。

The Research and Design of Intrusion Detection System
Based on Windows
——Design of Response Module

Abstract
The intrusion detection technology is complementarities for traditional security protecting technology, such as firewalls. It can identify and response to malice activities by monitoring the host system or the Internet. It also can prevent intrusion activities with the linkage of other security technology. The research and development of IDS has become the important subject about network security.
This thesis begins with studying attacking technology, including analyzing every stage of an intrusion stage and various attacking methods, summarizing the fundamental reasons of various network security incidents and the trend of attacking technology, afterwards, introducing the classification of the intrusion detection system, analyzing various intrusion detection methods and string-matching algorithm.  Through research to make clear that the intrusion detection system based on rules is the most important intrusion detection technology, because of this theory, the design has developed a response module based on the rule match characteristic examination method. The system development environment is VC++ 6.0; the database adapts the MYSQL database. This system can implement the effective realization to the intrusion detection, and the interface of this software is friendly.

Key words: Intrusion detection; Response module; Rule-matching
