Abstract

Methods and systems for use in in analyzing cyber-security threats for an aircraft are described herein. One example method includes generating an interconnection graph for a plurality of interconnected aircraft systems. The interconnection graph includes a plurality of nodes and a plurality of links. The method also includes defining a cost function for a cyber-security threat to traverse each link and defining a requirements function for a cyber-security threat to exploit each node. The method further includes generating a set of threat traversal graphs for each cyber-security threat of a plurality of cyber-security threats.
