Application of cut-sets to network interdependency security risk assessment

摘要

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.
