Embodiment Construction
[0059] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0060]The main solution of the embodiment of the present invention is: by obtaining preset sample data, the sample data includes a training set and a test set composed of various event logs; The TF-IDF model is combined with a variety of machine learning algorithms to construct a fusion classification model; according to the fusion classification model, the risk level assessment is performed on the event logs in the test set. Therefore, through the TF-IDF model combined with a variety of machine learning algorithms, the risk level of the event log is evaluated, and the high-risk events in the massive security event log are intelligently identified, which greatly improves the identification accuracy of the event log and reduces the risk of high-risk events. The number of false positives of risk events reduces the workl...
