Honeypot technology is a network trap in cyber defense. It can attract and deceive attackers and record their attack behavior, so as to study the target and attack means of the adversary and protect real service resources. However, because of the static configuration and the fixed deployment in traditional honeypots, it is as easy as a pie for intruders to identify and escape those traps, which makes them meaningless. Therefore, how to improve the dynamic characteristic and the camouflage performance of honeypot becomes a key problem in the field of honeypot. In this paper, the recent research achievements in honeypot are summarized. Firstly, the development history of honeypot in four stages is summed up. Subsequently, by focusing on the key honeypot mechanism, the analysis on process, deployment, counter-recognition and game theory are carried out. Finally, the achievements of honeypot in different aspects are characterized and the development trends of honeypot technology is depicted.
