Research and Development of Cyber Cyberspace Resilience Technology

In the face of complex and unknown network attacks, it is impossible to provide comprehensive defense against all attacks. Therefore, Network Resilience will become a necessary design attribute of next-generation heterogeneous networks. Focusing on the research on resilience technology in cyberspace, the basic concepts and typical architectures of cyber resilience are discussed, and the research status and design methods of cyber resilience are discussed in terms of quantitative evaluation and system optimization. The existing research problems are summarized and analyzed, and the future development direction and challenges of elastic technology are prospected.
