摘要
入侵检测系统(IntrusionDetectionSystemIDS)是现代网络安全的重要组成部分,通过监视特定的计算机或网络,检测可能的攻击并做出反应,保护系统及信息的安全。IDS不仅帮助系统对付外来网络攻击,还可以查知内部合法用户的非法操作,扩展系统管理员的安全管理能力,是防火墙之后的第二道安全阀门。文章叙述了入侵检测技术的发展状况和关键技术,对现有系统进行了分类。
Intrusion detection technology is an active security technology.Intrusion detection system monitors the usage of protected systems,detects insecure states.It can not only help coping with external attacks but also detects the misuse of the legitimate users.IDS extends the securty administrator's ability and offers real-time protection to systems and is considered as the second line of defends behind firewall.In this paper we introduce the development and key technologies of IDS,give taxonomy of present systems.
