Abstract
Embodiments of the present disclosure provide techniques for distributing information about possible anomalies in a network. A sensor in a network may detect packets with payloads that match an anomaly signature. Address dispersion information, for example, in the form of source and address bitmaps, may be gathered at the sensor. The address dispersion information may be distributed to one or more peer sensors if the information indicates that the number of different addresses of the detected matching packets exceeds a threshold.
