Traditional security defense technologies, such as encryption, authentication, firewall, etc., were static and lagging behind, and honeynet was easily compromised. To solve this problem, a honeynet-based linkage model for network security is proposed. Then, its formal analysis is made. The concept of redirection is introduced, and its linkage mechanism is designed and implemented. Also, the simulation results validate the initial effectiveness of the system defense. Finally, the main task of the next step is pointed out.
