摘要
Techniques of preventing sabotage attacks in cyber-physical systems involve automatically identifying links between nodes of a graph representing cyber-physical systems as vulnerable to sabotage attacks according to a vulnerability metric for each link. The vulnerability metric used depends on the particular sabotage attack used to determine the vulnerable links. Once a computer configured to design cyber-physical systems based on vulnerability to sabotage attacks receives data representing the graph, the computer enumerates the possible links between nodes of the graph along which a sabotage attack may be performed. For each of those links, the computer computes the vulnerability metric. The computer then ranks the links according to respective values of the vulnerability metric. Based on the ranking, a designer may then perform a mitigation analysis that results in changes to the graph to reduce the vulnerability at each node accessible to a malicious actor.
