无线局域网安全设置优化研究

Optimization of Security Setting of Wireless LAN

探讨现行无线局域网面临的任意侵入、未授权使用等安全问题,剖析其存在的基本原理,阐述了无线局域网安全国际标准,并基于此深入分析WEP的认证和加密、禁用DHCP服务、物理地址(MAC)过滤、采用身份验证和授权、应用无线局域网的入侵监测系统、应用VPN技术等安全措施的原理和设置方法,最后提出选择各种措施的基本原则,为安全设置提供了参照标准。

The safety problems of arbitrary invasion and unauthorized use from the current WLAN are discussed.The international standard for the wireless LAN＇s safety is elaborated,the principles and setting methods of security measures such as authentication and encryption of WEP,forbiddance of DHCP service,physical address＇（MAC） filter,authentication and authorization,application of wireless local area network intrusion monitoring system and application of VPN technology.Finally,the basic principles of selecting various measures are proposed,and the reference standard is provided for security settings.
