Wireless network security for businesses

[aaaronic]

I work for a small company which sets up networks for small businesses. In the past, my boss would only setup simple WEP on the network. I was wondering how crackable WPA is? Is WPA or WPA2 the solution? I haven't seen any good information on cracking WPA besides running the key against a dictionary list.

Can anyone give me any further information on securing a wireless network beyond being cracked?

Thanks in advance...

A "good" dictionary attack is only way so far to crack WPA/WPA2. beyond that..unplugging your APs' power cord when its not in use is the only way to secure any Wi-Fi network.

Thanks for the quick answer! So if I use a very complex password with WPA, it should be strong enough for most uses (besides government, bank, etc...)?

WPA2 with RADIUS

Also, segregate wireless from wired.

And your good to go! The word you chose MUST be in the dictionary the "attacker" uses ..or all the other words in the world are useless to them.

Does the average Windows XP machine support WPA2 with RADIUS? How expensive is RADIUS to setup?

Is this necessary or is WPA with a very secure key a better option for a small business?

Also, how do you segregate wireless from wired? Can you elaborate on that please?

Remote Access Dial-Up User Service (RADIUS) Authentication and Authorization. RADIUS allows only approved users, via user name and password, access to the network. The server verifies the user before access is given. Different levels of access can be set up as well.


It uses certificates and usernames and passwords for security. I'm sure you can crack it..nothings uncrackable. If I had the set up for WPA2 Enterprize..Id like to take a shot at it myself. If you know the username and password..your in.

For small business..use WPA2 Personal with a key like mine..Capital..lowercase, numbers..spaces..special characters...and LONG!! The longer the better!..and if you forget the key...just reset your router and put another key in.

To make that clear, nothing of any business or sensitive information should pass over the wireless network.
