After much poking and prodding from various colleagues and customers, I’m finally hopping back on the blog train.

By this point everyone seems to refer to me as ‘The 1X geek’, probably because of my evangelical technical overviews and implementations of the standard. I s’pose because of this, in the past week several folks have asked me to check out recent articles by Mike Fratto (New Protocols Secure Layer 2, October 4) and follow up blog by Richard at Tao Security (Hop by Hop Encryption: Needed?) about 802.1X and the upcoming revision of the standard due in 2009.

I can tell you Mike always does his homework, and those of us interested in 1X get our technical details straight from the horse’s mouth, so to speak. Mike is no exception and I’m always comfortable referring readers to his blogs and articles for information.

To answer the questions I’ve received, I’ve put together a few bite-sized snippits of information on both the current 802.1X standard, its use with multiple device auth, its use with mixed authentication and the upcoming 802.1X-REV…

The Clearing Up 802.1X Series Begins…

We all know it… we all talk about… we all say how ‘bad’ it is. Yes, we know WEP SUCKS – so why are you still using it?

Yes- I’m talking to YOU! (more…)

Well, you’re not necessarily hearing it hear first, but it’s likely… unless you read IEEEdocs religiously (as I do) or read Paul Congdon’s standards updates at the ProCurve Networking site.

If you have no clue what 802.1X is, read my recent technology primer first. If you’re already familiar with 1X, you’ve probably heard about some of the 802.1X additions- the 802.1AE (MACSec) and possibly 802.1af (the key agreement for MACSec)… but that’s just the tip of the iceberg, and what’s hiding underneath will knock your socks off!

I run into two fundamental problems when I start to talk to customers or audiences about Network Access Control and its related standards and protocols. What are they? Number 1, most folks have no clue what 802.1X actually is. Number 2, for the most part, they don’t really understand what NAC is either. (more…)
