Build a Dynamic Psychedelic Network Environment through SDN Technology to Improve the Difficulty of Hacker Attacks

Facing more and more serious network security problems, the defender first adopts passive defense methods, that is, through intrusion detection, firewall, malicious code detection and other technologies, to defend against known viruses or attack methods. However, passive defense always lags behind the attacker. In today's increasingly complex cyberspace and increasingly demanding network security, this defense method has been unable to meet people's needs for network security. Therefore, this paper builds a DPNE through SDN technology to improve the difficulty of hacker attacks(HAs). This paper briefly introduces SDN technology, constructs a dynamic psychedelic network environment(DPNE), and discusses the difficulty of HA based on SDN technology and the deception of topology detection by psychedelic network environment; By improving the performance analysis of HA algorithm, it is verified that SDN technology has achieved good results in building a DPNE to improve the difficulty of HA.
