Network Anomaly Detection System Using an Attention-Based GNN
摘要
This paper introduces an anomaly detection system using the Activity and Event Network (AEN) model, Graph Neural Networks (GNN), and Graph Attention Networks (GAT). Our method gives more attention to neighbors with higher in-degree, highlighting their importance in the network. By combining the dynamic nature of AEN with the attention mechanisms of GAT, we can better identify anomalies in network behavior over time. Our approach effectiveness was assessed using two datasets and resulted in an accuracy of 88.3% and 90.7%.
