That means that setting up firewalls and other security mechanisms, securing the perimeter, is getting a real challenge and can result in very high costs.  
In order to adapt to the new requirements and to create a system that is compatible with the cloud- and the cooperate applications there is a new security approach: Zero Trust Security.Continue reading
