Abstract Today, the defense of sensitive areas and resources is a fundamental issue that encompasses all key infrastructures, and to achieve the goal of reducing the damage and injuries caused by the attacker, the use of informed and useful strategies is necessary. In this research, modeling is considered to optimize the protection of investment systems that have a series-parallel reliability structure and have a functional correlation with each other. In general, in this study, first considering the functional independence of subsystems, the probabilities of a successful attack, the system reliability structure and the game theory approach to finding the equilibrium point, a nonlinear programming model is proposed to determine the investment defense of systems. Then, by determining the reliability relationships despite the functional correlation between the subsystems, a linear programming model is introduced to determine the correlation coefficient of the subsystems and to redistribute investment to defend the systems. Finally, the proposed research model is used for a numerical example and the results are analyzed.
