[Abstract]:The dynamic assessment method of network security risk is studied to improve the accuracy of the assessment. At present, the network security risk assessment does not consider the changes of network indexes caused by different intrusion characteristics, mainly the same static fixed index changes before and after intrusion, and lacks the method of dynamic sustainable evaluation in different periods. In order to solve the above problems, a dynamic assessment method of network security risk based on feature mapping association algorithm is proposed. The operation features in the network are weighted and optimized, the abnormal features of the network operation are extracted, the error of abnormal feature extraction is calculated, and the error of abnormal feature extraction is compensated. According to the feature classification function of network anomaly feature, the constraint conditions of feature classification are calculated, the feature attribute mapping model is established, the feature mapping correlation is obtained, the classification of network anomaly feature is realized, and the dynamic assessment of network security risk is completed. The experimental results show that the dynamic assessment of network security risk by using the improved algorithm can greatly improve the accuracy of the evaluation and meet the actual needs of network security.
