摘要
由于无线链路的弱点,节点缺少物理保护,拓扑的动态变化,缺乏集中的监控点等,使得无线传感器网络存在着更多的安全问题。入侵检测技术可作为第二道安全防线来弥补入侵预防技术的不足,是当前研究的热点问题之一。文章结合目前无线传感网IDS技术的发展现状,对入侵检测方法、IDS模型进行深入分析,并针对静态IDS模型存在的问题,提出了一种动态的IDS模型,在安全性、稳定性和健壮性方面都有所改进。
Security is one of the most critical problems of Wireless Sensor Networks（WSN）,because of the vulnerability of wireless links,the absence of physical protection of nodes,dynamically changing topology and the lack of a centralized monitoring or management point.The intrusion detection approaches,as a second line of defence,can make up for deficiency of intrusion prevention approaches,and it is one of the hotspot problems in WSN.This paper analyzes current status of IDS,the methods and the models proposed on IDS in WSN.A dynamic model is proposed to improve the security,stability and robustness compared with static IDS models.
