A Cybersecurity Model for Decision-Making Problems Under Uncertainty Using Game Theory

We propose a new cybersecurity decision-making model based on game-theory and decision-making process. The proposed model allows the cyber defender to make optimal decisions by considering perceived damage, cost of potential defensive actions, and benefit to mission. We provide detailed examples and numerical results supporting our model to show how game theory can help the decision-making process for cybersecurity by focusing on situations of conflict between an attacker and a defender.
