Abstract
An enterprise network includes hosts running services. Some of the services have security vulnerabilities. There are one or more threat zones associated with the network. For example, a firewall may create two threat zones, one internal to the firewall and one external to it. A device profiler in the first threat zone profiles the hosts on the network and identifies the vulnerabilities that are present. A device profiler in the second threat zone determines which of the identified vulnerabilities are accessible from its zone. A risk module calculates the risk associated with a vulnerability based on the vulnerability's severity, threat level metrics for the threat zones, and an asset value of the host with the vulnerability. A reporting module prioritizes the vulnerabilities based on their risks.
