Part II of the Clearing Up 802.1X Series
Securing Multiple Device Authentication on 802.1X

VLANs and Multiple Device Authentication
I always say the road to insecurity is paved with good intentions, and implementations of 802.1X are some of the best examples. I find folks tend to be so excited if-and-when they get 802.1X working, that they don’t bother to put it through the ringer and see what’s actually happening on the switch once it’s working. (more…)

Part I of the Clearing Up 802.1X Series
Multiple Device Authentication and Mixed Authentication

Pure vs Applied 802.1X
There are a couple of issues mentioned in Mike’s and Richard’s posts that I’d like to address with the current 802.1X standard (802.1X-2004) as it relates to multiple device authentication. (more…)

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…

Support Me in my Walk to End Alzheimer’s!

I try not to blog too much about personal life, because -well- I assume it’s probably not of interest to anyone. Today, I’m going to make an exception here for a good cause.

Unless you already knew me (pre-blogging) you probably don’t know I had one grandmother who went on to better places after our horrible struggle with Lou Gehrig’s Disease years ago. But that’s a whole ‘nuther discussion. What’s today about?

My second grandmother (and only living grandparent now) is suffering from another, more common, affliction – Alzheimer’s. In recognition of her great achievements, and in support of the other millions affected by this disease, we have gathered the troupes and are participating in the 2008 Memory Walk.

Our team of about a dozen family members and friends will pound the pavement this Saturday, October 4th in Cary, NC in an effort to do our part!

Now, I will shamelessly ask for your support!

If you feel so compelled and want to join us, or donate online, PLEASE DO! Here’s how…

My Donation Page - JJ’s Memory Walk page
Our Team Page - ’Forget-me-nots’

I have a dream, I have a goal and I think I have lots of really great readers who will throw in some love and donations. Even $1.00 or $5.00 is GREAT.
