Bringing security policy and identity together
04/28/08
If the LAN is supposed to get smarter and help us improve security-and other control features - with enforcement, what does that mean for policy and identity? Right now, it seems like all these aspects are separate - do you see them coming together?

Enabling security with new switch architectures
02/25/08
Last month, I read about Juniper entering the switch market for the first time and Cisco introducing a new set of data center switches. I'm wondering how these new switches support the idea of building more security into switches.

Baking security into a switch
01/14/08
I read a little about Cisco's TrustSec architecture, and I'm wondering if it's something we should take a look at. It seems like getting more security built into a switch is a good idea, but I can't tell how realistic that idea is yet.

Fending off VoIP security problems

Is NAC worth it?
10/29/07
I read a lot of conflicting stories about NAC - some very positive and some dismissive. Is NAC over-hyped, or is there value in it?

NAC: Stand-alone appliances vs. built into the infrastructure

I have heard the term "Identity-based Networking" in relation to LAN Security. What is the relationship between identity management and securing the LAN?

What are some of the challenges in deploying NAC? What are the alternatives for LAN security?

How to limit what contractors can do on the network
07/16/07
We have contractors perform a number of critical services, such as managing our IBM blade servers. These staff have to be on the LAN, and they're long-time contractors, so trust levels run pretty high, but I know they shouldn't be able to go everywhere on the LAN. How can I limit their access while still letting them do their jobs, and most important, not making them feel like I don't trust them?
