Network Authentication
Interop Las Vegas 2009 is now in the rearview mirror. I came back with a lot of discussions still echoing in my ears. The gathering was smaller than last year but still a good turn out. Cisco conducted a poll among conference attendees. More than 70% of them picked security as an area of interests, higher than any other areas. And network authentication was a hot topic.
So what is network authentication all about? On a very basic level, it is about understanding who is coming to the network. There are a number of ways to implement network authentication. 802.1X is one of them (see my blog on Identity based networking services). NAC (network access control) is another. In fact, most NAC solutions on the market support 802.1X as a deployment option. So why is it that not everyone is doing network authentication today? No merit? Inconvenience for end users? Too costly?
