Software for the evidence of vulnerabilities in a computer network interconnects various data sources providing information about vulnerabilities and with their use determines which elements of CII are threatened by a given vulnerability. CII administrators will not have to actively monitor for vulnerability reports and manually search for vulnerable elements of the infrastructure, but will be provided with an automatically-generated list of active elements in the network with the identification of vulnerable or potentially vulnerable elements. The advantage of this approach is the ability to detect vulnerabilities in systems that are not directly managed by the security team, but the team has the ability to monitor the network traffic of a subordinate or its own organization.
