1. A method for analyzing network data, comprising:

  • obtaining network data indicative of communications between a plurality of computing devices across at least one network;

    processing the network data to generate a time-varying graph data structure, the time-varying graph data structure comprising node representations coupled by edge representations, each node representation corresponding to one of the plurality of computing devices, each edge representation corresponding to a communication between two of said computing devices in the at least one network and comprising data indicating a time of the communication;

    indexing the time-varying graph data structure for a plurality of time periods to generate a respective plurality of indexed time period representations, each indexed time period representation of the time-varying graph data structure comprising edge representations with a time of communication within a given time period in the plurality of time periods;

    obtaining an indication of at least one computing device within the plurality of computing devices that is associated with anomalous behavior and a time said anomalous behavior is detected;

    identifying an indexed time period representation associated with the time said anomalous behavior is detected; and

    starting from said identified indexed time period representation, processing the plurality of indexed time period representations to determine at least one further computing device within the plurality of computing devices that is also associated with the anomalous behavior.
