Network analysis in a file transfer system

摘要

Aspects of the invention are directed to a method and system for discovering business content transfer paths in a network using file transfer information, and for calculating business risk per network component in a network. A method according to an embodiment includes: obtaining file transfer information for a plurality of file transfers between a plurality of nodes within a network; generating a confidence of correlation for each pair of file transfers in the plurality of file transfers; determining interdependencies between the plurality of file transfers based on the confidence of correlation for each pair of file transfers; and determining a business content transfer path based on the interdependencies between the plurality of file transfers.

1. A method for determining a business content transfer path in a network using file transfer information, comprising:
obtaining file transfer information for a plurality of file transfers between a plurality of nodes within a network; generating, by a computing device, a confidence of correlation for each pair of file transfers in the plurality of file transfers, the generating the confidence of correlation including:
comparing file transfer sizes of the plurality of file transfers by:
analyzing header information associated with a plurality of packet transfers;detecting an end of file based on the analyzed header information; anddetermining a file transfer size based on the detected end of file, the end of file detected by:
detecting a larger than expected time gap between sequential packet transfers; and/ordetecting a packet having a size less than a maximum packet size; determining interdependencies between the plurality of file transfers based on the confidence of correlation for each pair of file transfers; and determining a business content transfer path based on the interdependencies between the plurality of file transfers.
