引言信息技术的发展带来了网络的革新,互联网在成为巨大机会的同时也成为了巨大风险。为了预防和组织网络上的各种恶意入侵,设计出了入侵检测系统。入侵检测系统(IDS)作为一种主动的对恶意入侵进行安全防护以保护信息系统的技术措施,从系统内部采集信息,分析可能存在的各类风险和安全入侵行为,以取得相应的安全防护效果。1入侵检测概述J.P.Anderson在1980年4月第一次阐述了入侵检测的基本概念,经过多年的发展,入侵检测方法在综合性和复杂性上不断扩
Introduction The development of information technology has brought about the innovation of the Internet. As a great opportunity, the Internet has also become a huge risk. In order to prevent and organize various malicious intrusions on the network, an intrusion detection system is designed. Intrusion detection system (IDS) as a proactive protection against malicious intrusion to protect the technical measures of information systems, collecting information from the system, analysis of all possible risks and security intrusion behavior, in order to obtain the appropriate security effects . 1 Intrusion Detection Overview J.P. Anderson first introduced in April 1980 the basic concept of intrusion detection, after years of development, intrusion detection methods in the complexity and complexity of continuous expansion
