Abstract: Systems and methods of associating security vulnerabilities and assets, and related Graphical User Interfaces (GUIs) and data structures, are disclosed. A definition of a security vulnerability, which includes multiple asset characteristics such as an asset platform that may be exploited via the security vulnerability and an asset platform that is affected when the exploited asset platform is exploited via the security vulnerability, is compared with definitions of one or more assets of an information system. An association between the security vulnerability and an asset is made if the definition of the asset includes a first asset characteristic of the security vulnerability definition and either the definition of the asset or the definition of another asset that has a relationship with the asset includes a second asset characteristic of the security vulnerability definition. The security vulnerability definition may also identify an asset platform that protects against the vulnerability.

Abstract: The invention is directed to providing threat and risk analysis for a network that has a high degree of inter-relationships and interdependencies among the assets comprising it, using a “cut set” enumeration method. The identified cut sets are used as the basis to the threat and risk analysis, since each cut set may affect the traffic between two dependent assets in the network, and thereby affect the security state of the dependent assets themselves. The affected security state may be confidentiality, integrity, availability, or other network or security relevant parameter.

Abstract: Information system service-level security risk analysis systems, methods, and Graphical User Interfaces are disclosed. Assets of an information system that have relationships with a service provided by the information system are identified, and at least one security risk to the service is determined by analyzing security vulnerabilities associated with the identified assets. A consolidated representation of the service is provided, and includes an indication of the determined security risk(s) and an indication of a relationship between the service and at least one of the identified assets. The security risk indication may include indications of multiple security parameters. Security risks may be represented differently depending on whether they arise from a security vulnerability of an asset that has a relationship with the service or a security vulnerability of an asset that has a relationship with the service only through a relationship with an asset that has a relationship with the service.
