Conversation with Jennifer Jabbusch on NAC, Part 1

von VPNHaus | 14.09.2010 |Expert Q&A, IT policy

Jennifer Jabbusch, a network security engineer and founder of the blog Security UnCorked recently tweeted a thought-provoking comment, "NAC is a philosophy, not a technology." We recently caught up with Jabbusch to dig deeper into this fascinating idea. To get this discussion started off, Jabbusch defined philosophy for us (via Wiki).

Philosophy is the study of general and fundamental problems concerning matters such as existence, knowledge, values, reason, mind, and language. It is distinguished from other ways of addressing fundamental questions (such as mysticism, myth, or the arts) by its critical, generally systematic approach and its reliance on rational argument. The word "philosophy" comes from the Greek φιλοσοφία (philosophia), which literally means "love of wisdom".

VPN Haus: You recently tweeted that NAC is a philosophy, not a technology. Can you explain what you meant by this?

Jabbusch:  Sure! See the definition above. It’s pulled from Wiki, but gets the point across. Network access control is a philosophy in that it truly is the result of studying fundamental issues of networking and security. NAC attempts to address some pret

VPN Haus: What does it take for someone to “get” the NAC philosophy? What is the biggest barrier in getting people to “get it”?

Connecting the dots is the hard part and that’s really where the opportunity to “get it” comes in to play. The ability to dissect the various vendor offerings and understand on a technical level how they’re accomplishing a feature (the means to the end) is how you “get it”. I realize I just said you need to understand specific technical pieces in order to get a philosophy, and I know that may sound backwards to many people. The complication is that NAC is NOT a product, it’s NOT a specific technology, so in order to understand the philosophy of NAC, you really have to understand all the possible pieces that are feeding in to it. Once you “get it” you’ll have that enlightened feeling that will help you and your organization pick the right solution.

Stay tuned next week for more from Jennifer Jabbusch, including NAC misconceptions and its poor market performance.
