Of the following, which can be a security benefit when using virtualization?
A. Patching a computer patches all virtual machines running on the computer.
B. If one virtual machine is compromised, none of the other virtual machines can be compromised.
C. If a virtual machine is compromised, the adverse effects can be compartmentalized.
D. Virtual machines cannot be affected by hacking techniques.
C. By using a virtual machine (which is one example of a virtual instance) any ill effects can be compartmentalized to that particular virtual machine, usually without any ill effects to the main operating system on the computer. Patching a computer does not automatically patch virtual machines existing on the computer. Other virtual machines can be compromised, especially if nothing is done about the problem. Finally, virtual machines can definitely be affected by hacking techniques. Be sure to secure them!
