Abstract

A method for finding, assessing and foiling attack paths on a vehicle on-board network is provided, wherein components connected on the vehicle on-board network represent nodes of a graph, in which an edge between a first node and a second node is a communication link between the first and the second node, nodes allowing access to the network are start or access nodes, nodes providing specific functions or access to specific functions are asset nodes, and wherein the edge is weighted and the weight of the edge is a cost required to attack the second node from the first through the communication link, a path is formed by at least one node of the graph, and wherein a probability value is determined for the path, for the at least one node of the graph reachable nodes connected to the at least one node are determined, and for each reachable node of the reachable nodes it is determined whether a cumulated cost of the path to the reachable node is within a predefined cost limit, and whether the probability value for the path including the reachable node is within a probability limit, and if this is the case, defining the path to be a probable attack path.
