Abstract
Official abstract text for this publication.
A method is provided in one example embodiment that includes generating a fingerprint based on properties extracted from data packets received over a network connection and requesting a reputation value based on the fingerprint. A policy action may be taken on the network connection if the reputation value received indicates the fingerprint is associated with malicious activity. The method may additionally include displaying information about protocols based on protocol fingerprints, and more particularly, based on fingerprints of unrecognized protocols. In yet other embodiments, the reputation value may also be based on network addresses associated with the network connection.
