Abstract
A system and method in one embodiment includes modules for identifying an asset with a vulnerability risk, identifying a service running on a port on the asset, identifying a connection to the port, calculating an operational dependence role of the asset as a function of the service and the connection, and modifying the vulnerability risk based on the operational dependence role. Other embodiments include identifying a protocol of a data packet at the port, classifying the protocol into a protocol category with a protocol importance score, calculating a connection average for the asset, classifying the connection average into a connection category with a connection score, and calculating a service dependence score. Other embodiments include calculating a host dependence score, assigning a data importance score to data communicated by the asset, and calculating the operational dependence role as a function of the host dependence score and data importance score.
