摘　　要：网络环境中存在多项确定性和不确定性影响因素,各项因素对整体网络环境的影响程度不同,通过研究多项网络影响因素作用下的网络威胁评估方法,可准确识别网络环境态势与潜在的发展趋势。以渔政管理系统网络管理日志数据为研究对象,构建基于集对分析理论的多因素网络环境威胁综合评估模型,通过集对势、偏联系数计算,分析了系统在攻击流量、威胁等级、相关度等方面的表现。评估模型提供了系统整体网络环境以及各项影响因素的威胁态势和潜在发展趋势,为渔政管理系统网络安全运维工作提供指导建议,也为信息系统网络威胁情报的分析和应用提供了研究思路。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.
