Cyberspace security protection strategy based on simulation modelling and digital twin technology

This paper mainly discusses the application of digital twin technology, elaborates on the security protection problems inherent in network digital twins from the level of access control, data protection and secure communication, and explores the methods of network digital twins empowering cybersecurity technology in the aspects of threat modelling and simulation, vulnerability analysis and remediation, and real-time monitoring and response. The digital twin technology in a cyberspace security application summarises the basic framework of the cyber digital twin: the physical system and the twin system can be based on cloud-side collaborative computing to carry out the basic framework of the cyber digital twin.
