入侵检测系统(IntrusionDetectionSystem简称IDS),顾名思义,便是对入侵行为的发觉。它通过对计算机网络或计算机系统中的若干关键点收集信息并对其进行分析,从中发现网络或系统中是否有违反安全策略的行为和被攻击的迹象。进行入侵检测的软件与硬件的组合便是入侵检测系统。与其他安全产品不同的是,入侵检测系统需要更多的智能,它必须可以将得到的数据进行分析,并得出有用的结果。一个合格的入侵检测系统能大大的简化管理员的工作,保证网络稳定,确保网络的安全运行。 Intrusion Detection System (IDS), as the name suggests, is the discovery of intrusion. It gathers information from several key points in a computer network or computer system and analyzes them to find out whether there is a violation of security policies or signs of compromise in the network or system. Intrusion detection software and hardware combination is the intrusion detection system. Unlike other security products, intrusion detection systems require more intelligence and must be able to analyze the resulting data to yield useful results. A qualified intrusion detection system can greatly simplify the work of the administrator to ensure network stability and ensure the safe operation of the network.
