Analysis on the cyber threat situation posture of the fishery administration system

Abstract： There are multiple deterministic and uncertain influencing factors in the network environment, and each factor has a different degree of influence on the overall network environment. By studying the network threat assessment methods based on the effect of multiple network influencing factors, the situation of the network environment and potential development trends can be accurately identified. Taking the network management log data of the fishery management system as the research object, a multi-factor network environment threat assessment model based on the set pair theory was constructed. Through the calculation of the set pair potential and partial connection number, the performance of the system in terms of attack flow, threat level, and relevance was analyzed. The evaluation model provided the overall network environment of the system and the threat situation and potential development trends of various influencing factors, and assisted in the decision-making of the network security operation and maintenance of the fishery management system. The evaluation model and research method constructed in this paper provided a research idea for the analysis and application of cyber threat intelligence in information systems.
