Over the past decade, we have witnessed a transition within security. From a product standpoint, we have started to depart from the dichotomy of IT centric versus security focused products. This divergence can be witnessed in network switches. In the past, security was focused on the perimeter with little attention given to the internal network. Behold the security in a box product, the firewall. A few years ago, a router/switch was purely dedicated to performance and moving packets from one location to another. Now we have seen these products incorporate features such as Dynamic ARP Inspection (DAI), dot1x for port authentication, DHCP Snooping, and much more. Lately Cisco has been focusing on this transition.
