This article aims to identify and clarify a hierarchical construct used by defensive cyberspace planners and operators to aid in mission decomposition, assurance, and terrain mapping. The model enables the visualization of complex relationships and equities between cyberspace assets, resources, and warfighting missions.
At a time when so many Department of Defense mission-essential tasks and functions are cyber enabled, it is more critical now than ever that we strive to model the highly complex cyberspace operational environment in an understandable and useful way. Modeling is a practical means to take logical components of cyberspace, tether them to physical assets, and illuminate how they ultimately support missions. We can then prioritize mission-critical systems and capabilities, organize the defense of those cyberspace elements, and gain confidence we are defending the right things at the right time. While this model is conceptual, it represents a first step toward automating cyberspace terrain mapping that will enable defensive cyber planners and DODIN Cyberspace Forces to respond to the dynamic, man-made terrain that makes up the cyber operational environment.
