By teammate Brit Weston and I recently gave presentations to the Seattle Windows Networking User Group (free pizza will make me do crazy things like this :>). I presented a lecture on wireless and 802.1X-authenticated wired security technologies (802.1X, EAP, WPA, and WPA2) and Brit showed a demo of the new wireless and 802.1X-wired authentication features for Windows 7 and Windows Server 2008 R2.
It was a lot of fun to be back in a pseudo-classroom setting, lecturing on wireless security details such as the extended initialization vector (IV) used by WPA and how WPA2 renamed the IV the Packet Number and uses it to derive the starting counter value for the AES/Counter Mode encryption algorithm. (I know, I know! Me too! I get goose bumps just thinking about it! :>)
Here is my “Securing Wireless and 802.1X Wired Infrastructure” presentation. For the supporting text, see IEEE 802.11 Wireless LAN Security with Microsoft Windows.
Here is Brit’s “New Windows 7 and WS08 Wireless Features” slide deck showing the new wireless and 802.1X-authenticated wired features for Windows 7 and Windows Server 2008 R2.
A splendid time was had by all.
