News.com (Jon Oltsik) writes about the need for a new outlook to security:
Fast-forward to 2004, and network security looks a lot like the host-based computing landscape of the early ’80s. Network security is based on scads of individual boxes and limited integration. What’s more, network security isn’t really part of the network; rather, it is an overlay on top of the network. Talk about inefficiency!
This federated approach to network security was sufficient 10 years ago, when companies had limited Internet access for low-priority activities, but this is no longer the case. Fragmented security architectures are a liability today, because they are expensive, an operational burden and can’t provide adequate security protection. Otherwise, they’re great.
Given the growing scope of threats and the limitations of current security architectures, a new model is warranted that integrates security functionality across the network. To borrow from Sun Microsystems, in the future, “the network is the security.”
