Design and Implementation of Endogenous Security Cyber Range based on Digital Twin Technology

As an essential and important infrastructure for the research, testing and verification of cyberspace security technologies and offensive and defensive drills, cyber range has been increasingly valued by governments and cyber security enterprises. This paper studies the key technologies of the current cyber range and digital twin technology, proposes an endogenous security network range model based on the digital twin model, designs a virtual and real combination network scene generation algorithm based on the multi-commodity flow model, and constructs an endogenous security network target range with endogenous security properties. It allows for the validation of resource control strategies and the analysis of attack traffic, thereby enhancing the reliability, availability, and security of network systems. Based on the constructed endogenous security network range, six “Qiangwang” mimic defense international elite Challenge competitions were held. The successful holding of the challenge fully verified the correctness of the cyber range model based on digital twin technology and virtualization technology. This endogenous security network range can represent the future development trend of cyberspace target range.
