Claim One:
1. A method for use in analyzing cyber-security threats for aircraft systems, said method comprising: generating an interconnection graph for a plurality of interconnected aircraft systems, wherein the interconnection graph includes a plurality of nodes representing at least one of an aircraft system of the plurality of interconnected aircraft systems, a software process, a data-store, and an input vector, and a plurality of links representing interaction between the plurality of nodes; defiling a cost function for a cyber-security threat to traverse each link; defining a requirements function for a cyber-security threat to exploit each node; and generating a set of threat traversal graphs indicating an impact of each cyber-security threat of a plurality of cyber-security threats on the plurality of interconnected aircraft systems, the set of threat traversal graphs based on an evaluation of a number of nodes and links capable of being traversed by each cyber-security threat of the plurality of cyber-security threats to determine vulnerabilities in the plurality of interconnected aircraft systems.
