1. A method for detecting outlier users of a network resource comprising:

  • monitoring stream data associated with a subscriber'"'"'s usage of a network resource for a predetermined time interval;

    deriving, from the stream data, a flow-count history, where a flow is a communicative connection between a particular source IP address and transport layer port to a particular destination IP address and transport layer port in which all of the packets are using the same protocol, and a flow-count history is a count of the number of flows the subscriber initiates as either the source IP address or destination IP address during a predetermined time period;

    applying the outlier detection logic to the flow-count history as compared to a plurality of other flow-count histories associated with a plurality of other subscribers; and

    assigning a flow-count band to the subscriber based on the outlier detection logic as applied to the flow-count history.
