“The Network is the Security”

Interesting article by Jon Oltsik over at news.com. Its titled The Network is the Security. He asks: Why is network security based on scores of individual boxes with limited integration. Why is network security an overlay on the network rather than the network itself?
He argues that when a computer is turned on the network should know who they are and what they have access to. And if people are doing something they shouldn’t then security staff is alerted.
The network should perform firewall, IDS, IPS AV and content filtering. It should create a model of “normal” traffic as a baseline for anomaly detection.
Jon then goes on to review the leading vendors.
