• ICA-WFS
• network behavior analysis

In this letter, a new definition of two-stage spatiotemporal approach, called ICA-WFS (Independent-Component-Analysis-Weighted-Frequent-Substructure) is proposed. To facilitate capturing abnormal behavior across multiple networks and dimensionality reduction at a single Point of Presence (PoP), ICA is applied. With application of WFS, an complete graph is examined, unusual substructures of which are reported. Experiments are conducted and, together with application of backbone network (Internet2) Netflow data, show some positive results.
