入侵检测系统中文件完整性检查的研究

Research on File Integrity Check in Intrusion Detection System

1 引言 随着计算机技术特别是网络技术的发展,开放的互连的计算机系统为通信和资源共享提供了便利,但随之而来的是更多的系统安全问题.系统的安全是一个体系,建立在各种安全机制集成的基础上[1],入侵检测系统(Intrusion DetectionSystem,简称IDS)作为系统安全的一道重要防线,主要是通过多种手段监控系统来发现入侵.

File Integrity Check is not only an important intrusion detection methods, but also play an important role in helping detecting when using other methods. This paper introduces a method of designing File Integrity Check System, which will strengthen the intrusion detection system.
