The game theory described in Chaps. 2 and 3 offers versatile possibilities for quantifying cyber deception. Yet specific game-theoretic models must be carefully chosen in order to model different types of deception. In this chapter, therefore, we propose a taxonomy that classifies deception into six categories. We then propose game-theoretic models that fittingly describe each category. Our analysis is based on both theoretical considerations and an empirical study of 25 recent articles in game theory for defensive cyber deception. The taxonomy provides a systematic foundation for understanding the three types of defensive deception that we study in Chaps. 5 – 7.
