Abstract

The invention discloses a network security information sharing system and method based on expert joint evaluation, electronic equipment and a storage medium, and belongs to the technical field of network security. The problem that an existing network security information sharing mechanism is large in member analysis ability difference and low in risk research and judgment accuracy is solved, a dynamic weighted expert committee and an active learning thought are introduced into the information sharing and research and judgment process, a center node conducts risk category research and judgment on all security information through a trained risk classifier, a research and judgment result is fed back to node experts, the experts improve the analysis process of the experts according to the research and judgment result, and the center node uploads all safety information and risk categories output by the risk classifier to a superior data service processing center after performing data backup on the safety information and the risk categories, so the risk research and judgment accuracy in the network security information sharing mechanism is greatly improved, and the member analysis capability in the network security information sharing mechanism is enhanced.

Description

technical field [0001] The present application relates to a network security information sharing system, method, electronic equipment and storage medium, in particular to a network security information sharing system, method, electronic equipment and storage medium based on expert joint evaluation, which belongs to the technical field of network security. Background technique [0002] In recent years, the intensity of network security attacks has further escalated, and organizations can no longer rely on isolated, thin, and fragmented network security information for defense. Therefore, the establishment of a network security information sharing mechanism has become a top priority in the current network security work. The network security information sharing mechanism can effectively alleviate the problem of information asymmetry, mobilize and coordinate the whole society to realize real-time group prevention and group governance, and improve the effect of network security g...
