入侵检测系统的现状与发展趋势

本文较为全面地介绍了入侵检测系统（Intrusion Detection System,IDS)，包括IDS的发展过程、分类、工作原理以及技术现状等，其中详细论述了入侵检测系统对网络攻击的检测，并且对入侵检测系统目前所关注的几个问题如针对IDS的规避、拒绝服务攻击着重进行了分析，最后结合自己的研究成果从入侵检测的策略、体系、技术三个层面提出了IDS的研究热点以及发展趋势。

Current State and Trends of Intrusion Detection System

This paper gives a fully discussion on ID systems, including their development, taxonomies, mechanisms and current technical state. The detection of networking attacks enforced by IDS is introduced in detail, with an emphasis on some topics that are more cared currently such as evasion and deny of service. Finally, the paper also points out some hot issues in the research of IDS and where it is headed in the future respectively from three aspects: strategy, architecture and technology.
