There was recently a rather heated twitter discussion between @Guisebule, @VirtualTal, and @Texiwill (myself) about using virtual desktops as a part of cyber defense. While this could be true, there is a need to ensure you know where your virtual desktop(s) start and end, not only within the network, but your applications in use. In addition, it is very important to fully understand the scope of a virtual desktop architecture as well as use. There are some use cases that work very well for use of virtual desktops as a part of cyber defense or for that matter just make sense for virtual desktops. There two ways to make virtual desktops part of your cyber defense but they both require more than network security.
