Network Security Situation Assessment Based on Kalman Entropy Model

Aiming at the problem of network security situation assessment, an estimation method is proposed based on Kalman entropy model. Key factors influencing the network security is selected according to the entropy correlation in order to construct regression equation, which help establish the state model and the measurement model of network security assessment. Then Kalman filter is used to estimate the network security situation. Results show that this method can accurately estimate the network security situation.
