Clearing Up 802.1X

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…

I luv you’z guys and I usually agree with both of you on all matters NAC-ish and 1X-ish, but I have to disagree with today’s flurry of 802.1X-adoption talk.

What exactly am I yapping about? Well, today Tim at Network World posted a nice article on the growing adoption of 802.1X. Shortly after, Alan jumped in with his post on ‘Is 802.1X in Your Future?’. You can see my notes below, and I definitely recommend reading the original articles. (more…)

The Not-So-Sweet Life of Supplicants

There are plenty of integration and configuration challenges when we look at 802.1X, but one of the most notable issues is choosing the right supplicant to best serve your end users.

Some of the major obstacles we face with 802.1X center around creating a smooth end user experience.  We, as integrators, have the distinct ability to make ‘whatever’ work- we find a way. But, what I hear most from my customers is “it has to be easy for the end user.”  (Sometimes they go on a little further, but I’ll leave it at that.) (more…)

I’ve gotten a lot of questions recently about using 802.1X on the wired interface with Windows XP SP3. In the past few weeks I’ve also stumbled across a lot of forum posts, blogs and articles stating you ‘can’t do wired 802.1X with XP SP3.”

Well, sure you can! There is a little trick now, though. (more…)

I’m juggling blog-moving with blog-posting and trying to find the happy medium. Coming soon though, are two NAC/1X series I hope you’ll enjoy… (more…)
