Subject: Wireless Security

	I am currently working on a wireless solution for some big
enterprises. The solution we chose was to implement WPA2 which includes AES
encryption. We wanted something cheap for businesses to deploy while
maintaining a high level of security. WPA2 is part of the forthcoming
802.11i security standard. Although it is not ratified, many devices have it
implemented already. Anything with the broadcom 802.11g chipset has AES with

	If you are worried about central management and authentication level
encryption, you should go with a radius server and client. We chose funks
solutions which uses TTLS to authenticate the client and encrypt the data.
After the user info is verified it sends the encryption to the AP to use AES
between the client and itself. If you need more info, feel free to respond

Hope this question isn't off topic, 

I am currently looking at securing wireless networks using Cisco hardware
and wanted to check what peoples thoughts are on security.

I have read about using LEAP and also IPSEC, my concerns about using LEAP
would be that although the client and access point send hashes of the
username and password, and also dynamically create WEP keys, the process is
still vulnerable to brute force attacks.  Now i know you can lock down the
Access Point (AP) to specific MAC addresses, however, in our environment i
can see wireless being used for meeting rooms etc, so the users would be
random which would mean the constant addition / removal of MACs to the AP
which would probably not be possible or practical all of the time.
Although policy could dictate that when a wireless card is given out, the
MAC address in added to the AP, however if you have multiple APs in
different areas of building, being administered by different IT depts then
this could soon become be a problem.

To me IPSEC looks like be the better solution using SecurID tokens (one time
passwords) to authenticate users, any thoughts would be appreciated.
