Abstract: According to the specific construction demand of military networks defense system, this paper proposed a new military network defense in-depth model of APR-WPDRRC based on closed-loop control mechanism. Since the model adopts technique policy of multilayer defense in-depth and integrate layer-class frame of defense in-depth technique method, it can achieve cooperation linkage and closed-loop control of fast warning, initiative protection, real-time detection, urgent response, dynamic restore and precision counterattack. hhe model has a good networks defense agility of adaptability, intrusion tolerance attack and strong survivability when it is confronted with large-scale, distributed, instantancous changing network attacks.
