Currently, there is not a unified security strategy in military networks’ security system. So, the security of important information in military networks is not yet guaranteed. In this paper, a defense system is put forward, which is an advanced P2DR model with honeypot technology. By optimizing honeypot deployments and redirecting the intrusive actions, this system has effectively improved the pre-detection ability on network intrusion, and the P2DR performance. It is also used in elementary applications of the military networks, which has boosted the defense capability of military networks.
