[0049] Below in conjunction with accompanying drawing, the present invention is described in further detail:
[0050] Such as figure 1 As shown, the present invention proposes a network security situation assessment method based on artificial immunity and multi-scale entropy, which includes six parts: original feature extraction, multi-scale entropy calculation, detector training, network threat security detection, network security Situational computing and situational visualization. Among them, the original feature extraction is to obtain the original network packet features from the network through the data collection module, which is used for the subsequent multi-scale entropy calculation and network anomaly detection process; the multi-scale entropy calculation is to perform multi-scale entropy on the extracted network features. Calculation, calculate the sample entropy of the original data packet feature sequence at different time scales, and obtain the entropy feature v...
