摘　　要：企业局域网是互联网应用最广泛的一种组网方式,随着其规模和应用范围的不断地扩展,在提高网络服务质量的同时,如何保证网络的安全性和稳定运行是需要解决的问题。以当前国内外局域网安全问题的现状为突破口,对网络带来的威胁和相应的动态安全理论模型进行了相应的阐述。详细分析了动态安全模型的演变过程,对较为典型的PDR模型、PPDR模型、CISCO安全模型进行了详细分析和对比。采用模糊综合评判法对企业局域网进行网络安全评估,以期为局域网整体安全体系的构建打下基础。Enterprise local area network（LAN）is one of the most widely used networking methods in the Internet.With the expansion of its scale and application scope,how to ensure the safety and stable operation of the network is a problem to be solved while improving the quality of network services.From the current situation of LAN security at home and abroad as a breakthrough,it has elaborated the threat brought by the network and the corresponding dynamic security theory models.In the analysis of evolution process of dynamic security models,the typical PDR models,PPDR models and CISCO security models are analyzed and compared in detail.The fuzzy comprehensive evaluation method is used to evaluate the network security of the enterprise LAN in order to lay the foundation for the construction of LAN′s overall security system.
