A real-time anomaly detection method for network security based on data equalization technology

Abstract

The invention relates to a real-time network security anomaly detection method based on a data equalization technology, comprising the following steps: extracting network data from a database of a power communication network, and selecting corresponding data features for preprocessing to obtain preprocessed data; equalizing the preprocessed data with an Adasyn-based equalization algorithm; establishing a network security anomaly detection model through the equalized data; and importing the data features into the network security anomaly detection model to realize real-time detection on the network security anomaly. The real-time network security anomaly detection method based on the data equalization technology fully considers the defect that data is not equalized in the conventional method so that the prediction accuracy of the corresponding algorithm is relatively low; and the method fully considers the difference of data points while equalizing the data according to the features ofthe data, thereby effectively equalizing the data and improving the progress and efficiency of detection.
