Optimal allocation of Defense sources between the two approaches of active and passive defense defense.

If defensive decisions are classified in terms of the type of defense, they can be divided into two categories: passive defense and active defense. The researchers' goal of active defense in this study is preventive attack. In fact, this type of defense seeks to implement the famous phrase "the best defense is attack." In some articles it is referred to as preventive attack. Passive defense means reacting to enemy attacks after being attacked using both active and passive defense approaches. In fact, in passive defense, he must stay in the defensive shell and react to the enemy’s operations. The attacker will similarly seek to balance his or her assigned resources in two areas, attack and self-defense, against a Preventive attack.The Defender makes his or her decisions to take preventive attack based on the estimated probability of being attacked. In both cases, whether or not a preventive attack is taken, the defender considers the worst-case scenario of the attacker. In this article, in addition to expanding the above concepts, we analyze the effect of the ratio between the sources of the parties and the tendency to attack and examine the strategies of both parties.
