I have talked to many IT Pros over the years about using IEEE 802.1x to secure their wireless networks. One thing that I always found interesting is the number of people who are unaware that 802.1x isn’t just for wireless networks….wired too! If you network switches support 802.1x and you are running Windows Server 2003 – you have everything you need to start implementing 802.1x to authenticate access to your wired networks as well.
This new Whitepaper is a good read (or refresher) on 802.1x and IPSec and how they can be used to compliment each other to provide authenticated and encrypted communication on a wired network. (You will also find some details about 802.1x in Vista and Windows Server Codenamed "Longhorn")
