This presentation provides an overview of an IDA-developed cyber wargame that explores decisions about cyberspace force employment and network security postures. The wargame realistically emulates the nature of operational cyber conflict with a dynamic Opposing Force (OPFOR) that has a chance to “win,” a double-blind approach that replicates cyber uncertainties by revealing limited information to each side, and a force-on-force approach that assigns capability values to friendly and enemy units and networks to facilitate adjudication, and with no unrealistic constraints on the OPFOR. It may be planned and executed at the SECRET level or higher, simulates one week of “real scenario time” per one-hour game turn, can be tailored and scaled to examine the “customer's” decisions and cyberspace terrain and is relatively simple and “lightweight” to plan, teach and execute.
