Network Security 2.0: Layered Security or Systems Approach?

Listen to the Podcast

Fred KostThe conventional wisdom in IT threat mitigation is to build a layered defense with security technology such as firewalls, IPS, network access control, anti-x client software, alarm aggregation and event correlation, etc. Conventional wisdom is starting to shift toward a systems approach to protecting IT assets. The layered approach was built upon deploying best-of-breed products, which were best-of-breed only until other products emerged and relegated them to either stand-alone appliances and/or loosely coupled silos such as the linking between IPS and firewalls. The systems approach builds upon IT security investment by wrapping it with System Management for policy, reputation and identity that transcend end-pointss, networks, content and application security. Fred Kost, Cisco's Director Security Marketing is my guest as we explain the new IT security model and provide IT leaders with guidance on building a more secure IT infrastructure.
