Endpoint Posture Validation (aka NAC)

I recently encountered the The Internet Protocol Journal produced by Cisco. It is rather technical but I have found some of the articles to be valuable and interesting, particularly the article Geographic Implications of DNS Infrastructure Distribution in the March 2007 issue.

In the current issue, June 2007, the article “Network Authentication, Authorization, and Accounting Part Two: Protocols, Applications, and the Future of AAA”, Sean Convey used the term Endpoint Posture Validation:

Finally, another important AAA application is Endpoint Posture Validation, also referred to as Network Access Control (NAC). Unfortunately NAC is an inappropriate name because of its almost complete overlap with the more general AAA term—leading to a fair amount of confusion in the market. Endpoint posture validation refers to many different parameters in the industry as it is an emerging technology. These parameters range from very narrow device-centric posture checking to a more identity-centric approach for secure mobile computing. Because this entire article is concerned with the latter, we will consider NAC in its narrow context of endpoint posture checking. With this label, NAC simply acts as another PIP for the PDP to use.

I really like the term Endpoint Posture Validation (EPV).

  1. Not that I’m impressed a lot, but this is a lot more than I expected for when I found a link on Delicious telling that the info is awesome. Thanks.
