By now it’s obvious to any security-minded developers or IT professionals, that as applications move to the public cloud, the definition of the “perimeter” changes. You can no longer rely on network perimeters to manage access, prevent attacks, and control traffic since you no longer manage the network. In fact, you can only trust the network in the public cloud to the extent that you understand it and have predictable, efficient ways of managing it. Because the network perimeter essentially no longer exists, or at the very least is expanded to include the virtual boundaries of your cloud environment, your security models start to break down. Most organizations today are either just establishing teams and expertise to focus on the nuances and rapid evolution of cloud security, or in far too many cases, they are only beginning to understand that things are different.
