[Research purpose]Cyber security situation awareness is the basis of dealing with cyber security crisis.Cyber security situa-tion awareness based on threat intelligence can effectively solve the problems such as large amount of data are unstructured,and difficulty in quick processing.[Research method]This paper analyzes a large number of related literature,makes full use of the relevant knowl-edge of security science,information science,systems engineering and other fields,and makes the model at last.[Research conclusion]In this paper,the model is a complete process of detecting,understanding and predicting cyber security intelligence in the"physical-socie-ty-information"tridimensional space.In the model,the key factors are human's cognitive level,attention and memory,and the decision and action based on them.The paper puts forward the operating rules that supports the three links of the model:understanding,prediction,and emergency response support.
