In traditional physical networks, there was always some type of air gap [1] that existed or could be made by unplugging a cable between systems on a network. For example, you have two computers that are physically connected to the same network. If you unplug/disconnect the network cable or add a firewall between those two computers, they will not be able to communicate with each other. In a virtualized environment, the hypervisor always creates a software connection between systems, NOT a physical one. And since it is software based, there is no way to completely isolate one operating system from another. As a cybersecurity engineer, discuss the possible solutions to solve this problem in virtualized environments.
