We set out to analyze these next-generation network access control models. Many include the concept of network node validation, or NNV--that is, identifying and verifying nodes attempting to join the environment. We wanted to know which strategies help with which problems, and what organizations should expect from this intelligent infrastructure. In this article we examine competing vendor strategies and discuss operational concerns organizations should watch for. In "Catching Rogue Nodes", we take an early look at next-generation technology from Cisco Systems, Juniper Networks and start-up ConSentry Networks. We also examine how multivendor implementations from companies like Sygate (now Symantec) approach the problem.

We found that all initiatives are not created equal--some components are baked, while others must go back in the oven. In addition, these technologies will cause non-technical changes as well as technical ones.
