Intelligent Awareness Method of Power 5G Network Security Situation Based on Neural Network and Fuzzy Theory

5G introduces new technologies and new architectures, while also facing more complex security risks and threats. Power companies use leased 5G network slices to form a network symbiotic relationship with operators. The security of 5G network directly affects the safe and stable operation of power grid. However, power companies only own part of 5GC network elements, so it is necessary to carry out network security protection research for key parts of 5G network architecture. Through the research of 5GC security situation awareness technology, it can deal with 5G security challenges and help power grid companies operate 5G network slices efficiently and safely. This paper proposes a network security situation awareness method based on fuzzy theory and gated recurrent unit, which can convert attack information and network information into network situation, provide quantitative indicators of network security, and detect and respond to potential threats in time.
