The application of game theory in cybersecurity enables strategic analysis, adversarial modeling, and optimal decision-making to address security threats’ complex and dynamic nature. Previous studies by Abraham et al. and Biçer et al. presented various definitions of equilibria to examine the security aspects of games involving multiple parties. Nonetheless, these definitions lack practical and easy-to-use implementations. Our primary contribution is addressing this gap by developing Gamu Blue, an easy-to-use tool with implementations for computing the equilibria definitions including k-resiliency, l-repellence, t-immunity, (l, t)-resistance, and m-stability.
