Buzzword watch: Network Access Control

Chances are you're aware that a firewall protects the front end of your system. What about the back end? More companies are starting to adopt network access control measures to protect the system from within. While investment in internal protection still sorely lags, attitudes are changing. NAC appliance sales, by one measure, reached $83 million during 2006. That amount is expected to double this year. Whew! The heavyweights in the market include Microsoft, Juniper, HP, Extreme, Enterasys and Aruba among others.

You'll be hearing about it most likely.
