摘    要:入侵防御系统(IPS)是能够检测到任何攻击行为,包括已知和未知攻击,并能够有效地阻断攻击的硬件或者软件系统.讨论了入侵防御系统的概念和特征,分析了当前IPS的4种实现模型(在线模型、7层交换模型、7层防火墙模型和混合模型)的优缺点.为解决这些模型在同时提高网络性能和入侵检测准确度方面的难题,给出了一个基于WindForce千兆网络数据控制卡的嵌入式入侵防御系统的实现实例.

关 键 词:入侵防御系统  网络入侵防御系统  嵌入式入侵防御系统  高速网络  入侵检测系统  防火墙  网络安全  入侵防御系统  研究  system  prevention  intrusion  嵌入式  控制卡  网络数据  千兆  检测准确度  网络性能  混合模型  防火墙模型  交换模型  在线模型  实现模型  分析  概念和特征  软件系统  硬件

Abstract:Intrusion prevention system (IPS) is defined as any hardware or software systems that are capable of detecting attacks, both known and unknown, and preventing the attacks from being successful. Firstly, the definition and properties of IPS is discussed, then advantages and disadvantages of four current IPS implementation models are analyzed, i.e. in-line model, layer seven switch model, layer seven firewall model and hybrid model. And as a result an embedded IPS implementation solution based on Giga-bit network data control card called WindForce is presented, aiming at solving the dilemma of those models of improving both network performance and precision of intrusion detection simultaneously.
Keywords:intrusion prevention system (IPS)  network based IPS  embedded IPS  high-speed network  intrusion detection system (IDS)  firewall  network security
