  • System, method, and software for cyber threat analysis
    Patent number: 9241008
    Abstract: According to certain embodiments, a cyber threat analysis system generates a network model of a network infrastructure that is used by an organization, assigns a weighting value to each of a plurality of network elements of the network infrastructure according to a relative importance of the each network element to the organization, and generates an attack vector according to a determined vulnerability of the network infrastructure. The attack vector represents one or more illicit actions that may be performed to compromise the network infrastructure. The system may simulate, using a network modeling tool, the attack vector on the network model to determine one or more resulting ramifications of one or more of the plurality of network elements due to the attack vector, and determine a criticality level of the attack vector according to the weighting value of the one or more network elements.
