In order to increase the security of wireless networks

In order to increase the security of wireless networks, companies can use the "user-based" rather than "based on the device MAC address authentication mechanism. In this way, the laptop battery, even if the user's laptop is stolen, thieves not have a laptop user's user name and password, can not access the network. This method is simple, at the same time will reduce the administrative burden, because there is no need to manually manage the MAC address table, but companies need to evaluate and deploy the AP to support user-based authentication database. The validation database you can locally within the AP for maintenance.

This multi-level strategy, so that each user has a unique key, the key can often change. Hackers encryption mechanism, and obtain access to the network, but the the hacker acquired key valid for a very short, thereby limiting the potential damage. This method because of its design dynamic key management function within the AP, thus simplifying the administrative burden of the ever-expanding IT resources. Compared with the 128-bit shared key encryption technology, dynamic key management function is more powerful, often changing the key to further increase the difficulty of hacking system.

Specifically, users only need to take the following measures to wireless network security risks can be greatly reduced. First, control the wireless client to achieve the standardization of WLAN cards, laptop battery to prevent the WLAN card has been any changes; treated like the Internet, to treat WLAN, WLAN and wired networks install a firewall to prevent unauthorized WLAN users to the wired sent over the network Layer 2 packets; Third, is to protect the access point, the access point is hidden in places not easy to find, prevent illegal tampering; prevent radio waves "leak" into the outside of the site.
