A Combined Prediction Method for Network Security Situation

In order to improve the precision of network security situation prediction, a combined method for prediction was proposed. For the nonlinearity of network security situation value, the Method predicted the security situation by using ARMA model and Markov model. On this basis, it optimized the predicted results with combined strategy. The analysis of the example indicates that the combined method can effectively improve the precision of network security situation prediction, compared with single Method.
