Abstract: In the study of network security issues, many factors may cause the network to be insecure. The network security situation prediction technology can reflect the network security status as a whole. In order to improve the accuracy of network situation risk prediction, a network security situation prediction model based on extreme learning machine is proposed. Simulate by MATLAB to predict situation values. The simulation results show that using the learning model based on extreme learning machine, the learning speed is fast, the precision is high, and the network security situation can be predicted well.
