The New Enterprise Security Perimeter is no Longer a Perimeter
Have you ever looked at your dog or cat staring out the window of your house towards the horizon? Ever wonder if they contemplate what may be beyond their visible perimeter? It used to be that internal IT did not have to contemplate what lay beyond the perimeter. Network security was fairly simple – create a wall of security around the data center and its resources, along with the users and their desktops scattered throughout the building. Traffic passed through the perimeter firewall while users passed through the front building entrance to access the network. It was a page out of the medieval castle defense playbook in that unauthorized users, unknown devices and external threats were kept at bay outside of the walled perimeter.
