Aiming at network scanning and sniffing attacks, this paper designs an active defense mechanism based on virtual network topology, which generates a large number of random and independent fake networks through generative adversarial networks, and uses the traffic traction capability of software-defined networks to trick attackers into accessing preset defense hosts, making it impossible to detect the real internal network topology, and it is difficult to collect the element information required for attacks, such as key link sets and sensitive server collections. Experiments show that compared with the relevant defense mechanism, the proposed method has obvious advantages in protecting the server response experiment and file transfer rate.
