Threat situation prediction method and threat perception system applying AI and big data analysis

The embodiment of the invention provides a threat situation prediction method applying AI and big data analysis and a threat perception system, and the method comprises the steps: responding to an attack situation prediction instruction initiated by an attack detection server when the attack detection server detects a sensitive attack activity, extracting attack activity big data of an attacked cloud application, and transmitting the attack activity big data to the attack detection server; if it is detected that frequent attack activity data exist in the attack activity big data, collaborative attack activity data corresponding to the frequent attack activity data are output; and performing pre-configured threat situation prediction of at least two types of threat situation dimensions on cooperative attack activity data corresponding to the frequent attack activity data, and outputting cooperative attack threat situation information of the frequent attack activity data, therefore, threat situation prediction
