局域网安全威胁及防护分析

LAN security threats and protection analysis

局域网是在有限范围内实现数据通信和资源共享的封闭型计算机网络,因使用灵活、便于安装、易于扩展,被广泛应用于公司、企业、学校等构建高效的内部网络。大部分单位只注重局域网的应用建设,建设结构简单,但缺乏严密的安全措施,在享受局域网便捷的同时,也为病毒的传播提供了通道。因此,要深入了解局域网安全技术,认识到威胁局域网安全的因素,做好局域网安全防护工作,使得局域网在日益广泛的应用中提供更为高效可靠的网络平台。

Local area network（LAN） is the closed computer network that realizes over a limited range of data communication and resource sharing. Due to the advantages of flexible use, easy to install, easy to expand, it is widely used building efficient internal network of the companies, enterprises and schools, etc. But due to the lack of the strict security measures and simple construction structure, most units only focus on the application of LAN construction convenient. While enjoying the convenience of LAN, it also provides the effective channel for the spread of the virus. So we should deeply understand LAN technology, realizing the factors threaten the security of a local area network, doing a good job in local area network security protection. Then, local area network in the increasingly extensive application will provide a more effective and reliable network platform.
