Research on cyber security attack and defence strategy simulation in a virtual network environment

As the cybersecurity landscape becomes increasingly severe, the connection between people's economic and life safety and network information security is becoming more and more closely linked. This paper addresses the importance of cybersecurity simulation and offensive-defensive strategy research, proposing a simulation method for cybersecurity offensive and defensive strategies based on a virtual network environment. The method utilizes KVM virtualization technology to construct a virtual network environment and simulate various cybersecurity attack and defense scenarios, thereby aiding researchers in optimizing cybersecurity defense measures. This paper provides a detailed introduction to the architecture and operational modes of the KVM system, as well as the creation process of network attack and defense simulation virtual machines. The effectiveness of the method is demonstrated through practical case examples, and future research directions are prospected.
