Automatic Prediction System for Cloud Computer Room Network Security Situ-ation Based on Fault Tree
In order to fully grasp the running state of network security in cloud computer room and predict the network security situation,an automatic prediction system of network security situation in cloud computer room based on fault tree is designed.The cloud computer room module of the system uses log sensors to collect the network data of the cloud computer room,and stores them in the data management module.Based on the stored data,the functional module detects the abnormal data flow in the stored data through the time window,calculates the network risk of the cloud computer room by using the step-by-step quantification method,and then calculates the importance of the network secu-rity events of the cloud computer room by using the accident analysis method,and then analyzes the future changes of the network according to the results.The test results show that the system has a comprehensive ability to collect data related to network operation,and the quantitative effect of network security situation is good,and the determination coef-ficient results are all below 0.022.Effectively realize the quantitative analysis of risk situation prediction of IP address networks with different purposes,and reliably grasp the security situation of cloud computer room networks.
