The US Department of Defense (DoD) and the individual services are turning more and more to virtualization to improve the efficiency and flexibility of their IT networks. This technology allows multiple virtual machines with different operating systems to run side-by-side on the same physical machine. The main benefit is a decrease in needed hardware, space, and power to perform the same IT operations, thus saving money and weight on military IT systems and platforms.
At the same time, virtualization raises security concerns because traditional IT security products, such as firewalls, do not work in the virtual environment.
