The new 802.1X-2010 (formerly referred to here as 802.1X-REV) offers a multi-faceted approach to increasing integrity, availability and confidentiality throughout network infrastructures at every segment- from LANs and WLANs to WANs and MANs. Yeah, I threw out the I.A.C. triangle. As much as I hate using it, it is a foundational element of security. (more…)

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…)

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!
