A Reputation Game on Cyber-Security and Cyber-Risk Calibration

To analyze strategic interactions arising in the cyber-security context, we develop a new reputation game model which an attacker can pretend to be normal user and defender may have announce attack detection at certain point of time without knowing whether he has been attacked. We show existence uniqueness sequential equilibrium Markov strategies, explicitly characterize players' strategies. Using our model, suggest empirical theoretical ways calibrating probability, is important element cyber-risks.
