Abstract: A valuable alert screening method for detecting malicious threat includes generating an AI model based on training data for predicting test data, generating XAI explainability and selecting important features based on summary plot by using an explainer and training data, performing range processing based on data distribution of important features selected for analysis without bias, calculating a SHAP value average and standard deviation of each range group and then storing them to determine suspicion and reliability of test data, making prediction by using an AI model generated in advance after feature processing in the same way as the training data at the time of inputting the test data, calculating a SHAP value by using the test data and the explainer, loading FOS calculation information to calculate FOS for each important feature, and calculating a suspicion score for each data by aggregating the FOS after calculating the FOS for each feature.
