Network attack detection method and device, electronic equipment and storage medium

The invention discloses a network attack detection method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining a log file, and constructing an original traceability graph according to the log file; determining a degree information value corresponding to each node based on the connection edge of each node in the original traceability graph; modifying the original traceability graph based on the degree information value to obtain a first traceability graph; performing mask operation on the first traceability graph to obtain a second traceability graph; performing depth-first traversal on the second traceability graph to obtain an integrity measurement index; on the basis of the original traceability graph and the second traceability graph, mutual information is obtained in combination with an integrity measurement index; performing neural network training by taking the original traceability graph and the second traceability graph as positive and negative samples r
