【摘要】 入侵检测是保护网络和信息的重要举措之一。文章针对入侵检测系统被动监测的弱点,提出了一种结合端口扫描技术的入侵检测系统。通过主动扫描被保护网络,获取有效信息,动态地配置入侵检测系统,提高检测效率。同时密切监控未开放端口,有效识别外部扫描,提高检测的灵敏度。更多还原

【Abstract】 Intrusion detection is an important way to protect network and information.This paper presents an intrusion detection system combined with port scanning technique.By scanning the protected network actively and gathering neces-sary information,this system can dynamically configure IDS to improve detection efficiency.At the same time IDS will tightly monitor closed ports to recognize external scanning rapidly.更多还原
