| Summary: | In order to deal with the problems that the increasing scale of the network in the real environment leads to the continuous high incidence of network attacks, the threat intelligence was applied to situational awareness, and the situational awareness model based on random game was constructed.Threat perception of the target system was performed by comparing the similarity between the exogenous threat intelligence and the internal security events of the system.At the same time, internal threat intelligence was generated based on the threat information inside the system.In this process, game theory was used to quantify the current network security situation of the system, evaluate the security status of the network.Finally, the prediction of the network security situation was realized.The experimental results show that the network security situation awareness method based on threat intelligence can reflect the changes in the network security situation and predict attack behaviors accurately. |
