Abstract: Abstract: Network anomalies can seriously influence the normal operation of infrastructure and cause huge financial losses. Existing studies perceived the changes of network state by observing the changes of network traffic. However, due to the lack of quantitative indicators, these cyberspace situational awareness methods have the problems of high false positive rate and low accuracy. This paper proposes a new cyberspace situational awareness method to address these challenges. Specifically, we use the public data set to obtain the traffic information of the links in the detection area. Firstly, a traffic critical value determination algorithm based on Wilson score is proposed to calculate the corresponding traffic threshold of each link. Secondly, a network state awareness scheme is proposed, which perceives the change of network state by monitoring whether the traffic volume of any link in the detection area is lower than the critical value and lasts for 11 minutes. Finally, this paper perform experiments with data from public measurement infrastructures (RIPE Atlas) to evaluate the performance of our approach, and the results show that our approach can effectively perceive the changes of network state.
