Abstract:

This paper proposes a network anomaly detection method based on immune bionic mechanism and graph neural network by imitating the risk prevention mechanism of biological system, which uses graph neural network to deeply mine the sub graph information near the node. While considering the content features of the network, the structural features based on graph were integrated into the model, which can be used as the basis of anomaly detection in the network, so as to better mine the anomaly information in the network. At the same time, graph representation learning technology was integrated into network anomaly detection to solve the problem of feature representation. Based on CICIDS2017 dataset, Cora dataset and Reddit dataset, the experimental results show that this method can better mine network anomalies and improve the accuracy of anomaly detection.

Key words: network anomaly detection, immune bionic, node, graph neural network, graph representation learning
