Cyber threats are often weak signals designed to exploit targeted systems. These signals manipulate cyber, psyber, and risk communication components of the signal to diminish signal-to-noise ratio. Cyber components are the physical aspects of the signal that can range from viral code to the use of aberrant signals from the electromagnetic spectrum to confound operations such as global positioning systems. The psyber component includes the behavioral propensities of the individual operator and level of experience detecting and managing threats. Risk communication is the tension set by the organizational culture priming individual operator propensities. The psyber components affect the ability to perceive contingencies. The risk communication sets the signal detection threshold for distinguishing true threats from false alarms. This paper describes current simulation efforts to afford the application of evidence-based methods to discern weak signals and to accelerate the experience of operators in discriminating weak signals via immersive training simulations.
