提高无线局域网安全性的有效措施

Effective Measures for Improving WLAN Security

随着无线网络的普及,人们在感受其便利性的同时,遇到的安全问题也日益突出。针对无线网安全性问题,在分析无线网传输介质的特殊性基础上,对无线网受到的威胁来源进行了简要介绍,提出防范非法接入可以从隐藏SSID、合理设置安全验证方式、物理地址绑定、关闭DHCP和更改路由器管理端默认设置等方面入手,减少信号干扰则需要合理选址和避开同频段设备。根据实际应用场景将这些防范措施配合使用,可以有效提高无线网的安全性。

With the popularity of wireless network, people experience the convenience brought by wireless network, at the same time, they encounter some increasingly-outstanding security problems. Aiming at these security problems, the threat resources subjected by wireless network are introduced briefly based on the analysis of characteristics of transmission medium of wireless network. The prevention of unauthorized access can be conducted from the aspects of hiding SSID, reasonable setting up security verification mode, binding physical address, closing DHCP, changing default setting of router management, etc. The signal interference can be reduced by reasonable site selection and same frequency equipment avoidance. Based on the actual application scenarios, the application of these measures can effectively improve the security of wireless network.
