A Statistical Method for Profiling Network Traffic
David Marchette, Naval Surface Warfare Center B10
Two clustering methods
are described and applied to network data. These allow the clustering of
machines into "activity groups", which consist of machines which tend to
have similar activity profiles. In addition, these methods allow the user
to determine whether current activity matches these profiles, and hence
to determine when there is "abnormal" activity on the network. A method
for visualizing the clusters is described, and the approaches are applied
to a data set consisting of a months worth of data from 993 machines.
