wireless security in our wired LAN

Locked

Hi,

Our organziation has about 50 computers in a windows 2000 domain. A few people with laptops want to have the convenience of a wireless access point to access the network resources while they are in the building. I’m dragging my feet in implementing it because of security concerns. It wouldn’t be practical to allow access only to a certain segment of the network, because it would defeat the convenience factor. We would be using a D-Link DI-524. Even with WPA-2, MAC filtering, turning it off in off hours, etc, I’m still worried that it will leave us vulnerable. Would we be better off setting up a Radius serverrather than relying on WPA-2? Or would we be better off not using the wireless at all?

Opinons much appreciated..

nothing is 100%. With WPA 128 bit and mac filtering plus limiting access to certain hours along with domain credential requirements is pretty secure. Watch the logs for unusual activity as you would for your WAN link.

But no matter what there is nothing that is 100% effective but then again even your wired LAN is vulnerable to hacking by the internal users.

I’ve seen instances where someone wanting a free Internet connection has inserted a WIFI Hub in a suspended ceiling and come back after hours to access the Internet through the Companies Net Connection and this was without the Sys Admins knowledge.
