Claim One:
1. One or more non-transitory media including code for execution that, when executed by a processor, is operable to: obtain a plurality of host file inventories corresponding respectively to a plurality of hosts in a network environment, wherein each of the plurality of host file inventories includes one or more file identifiers, each of the file identifiers of a particular host file inventory representing a different executable file on one of the plurality of hosts corresponding to the particular host file inventory; calculate input data by transforming the plurality of host file inventories into a similarity matrix for the plurality of hosts, wherein for at least each unique pair of host file inventories of the plurality of host file inventories, the transforming includes: determining a normalized compression distance (NCD) between the unique pair of host file inventories; determining a numerical value representing a similarity distance between the unique pair of host file inventories, the numerical value being determined based on the NCD; and updating the similarity matrix to include the numerical value representing the similarity distance between the unique pair of host file inventories; and provide the input data to a clustering procedure to group the plurality of hosts into one or more clusters of hosts, wherein the one or more clusters of hosts are grouped using a predetermined similarity criteria.
