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.

Network transmission cabling

A network is a collection of devices connected by communication links. A device can be a computer or any instrument capable of sending and receiving data or information formed by other nodes toward the network. A channel that connects people or things is known as a network. It sends the data from one place to another. It is the basic concept of a computer, network, and data communications.
