无线局域网安全涉及因素众多,传统的基于入侵检测的被动安全分析系统,体系结构复杂、检测精度低。基于协议分析理论的主动安全分析方法,测试目标明确、可预测性强。脚本语言效率高,灵活性、可扩展性强,易于配置。本文有机地结合了两者的特点,设计出了一种基于Tcl脚本的WLAN主动安全分析系统,系统采用模块化设计,层次结构清晰,具备测试目的明确,可预测性强,系统配置灵活。针对安全实例,构造并执行了测试脚本,结果表明,系统能有效检测出无线局域网的安全问题。
Wireless LAN security involves many factors. The traditional passive security analysis system based on intrusion detection has complex architecture and low detection accuracy. The active safety analysis method based on protocol analysis theory has definite test target and strong predictability. Scripting language is efficient, flexible, scalable and easy to configure. This paper combines the characteristics of the two organically, and designs a WLAN active safety analysis system based on Tcl script. The system uses a modular design, the hierarchy is clear, the test purpose is clear, the predictability is strong, and the system configuration is flexible. For the security instance, a test script is constructed and executed. The result shows that the system can effectively detect the security problem of WLAN.
