- Although this can be done, most of the Wireless sniffers can actually still read this information so although its good to stop general people seeing it, if someone wanted to they could.
- Again, this can still be got around by spoofing the MAC address on the machine they want to gain access with. It may take some time to get the right MAC though as the number of possibilities are quite large.
- Much stronger then WEP however i beleive it is now crackable. WPA2 is much more stronger and would take a lot longer to crack.
All the above will help to secure your wireless, it all depends on how secure you want it.
I could be wrong here as its been a while since i read up on how to secure wireless but a few suggestions was to use Radius and EAP to authenticate the clients with the access points. Also setting up VPN's to secure the communications over the Wireless network (thats physically seperated from the rest of the network). This will then be able to use IPSec for securing the traffic.
