SYSTEM FOR ANOMALY DETECTION AND REMEDIATION BASED ON DYNAMIC DIRECTED GRAPH NETWORK FLOW ANALYSIS

Abstract:

Embodiments of the present invention provide a system for dynamic graph network flow analysis and real time remediation execution. Information for multiple accounts is extracted to generate a plurality of dynamic directed and undirected graphs made up of multiple nodes and edges. The nodes represent at least one of the multiple accounts, and each edge represents at least an association or transfer between two nodes. A custom entropy and divergence value is determined for each pair of nodes linked by an edge, as compared to similar or related nodes and edges. A nodal set of the graphs is identified as having aggregate custom entropy and divergence value that is associated with anomalous directional flow from a first node, across intermediary nodes, to a second node. A remediation action is executed with respect to one or more accounts associated with the nodal set in response to identifying the anomalous directional flow.
