摘要

The alert correlation process that aggregates computer network security alerts to the same attack scenario provides a coherent view of network status at a higher abstraction level. This letter proposes a framework called Alert-GCN to correlate alerts that belong to the same attack using graph convolutional networks (GCN). The intuition is that the stacked convolutional layers help aggregate alert information from farther neighbors in the alert graph, thus facilitating attack scenario discovery. Alert-GCN first transforms alerts into alert graph with one-hot encoding and then feeds the graph into the GCN to perform node classification. The experimental results indicate that Alert-GCN outperforms traditional classification models in correlating alerts.
