Identification and Evaluation of Cyber-Physical Threats on Interdependent Critical Infrastructures

Increasing interdependencies between critical infrastructures and digitization increase the vulnerability to cyber-attacks and cyber-physical attacks. Incidents have multiple direct and indirect con-sequences, including cascading effects, and a formal analysis is strongly recommended to understand these effects. This paper shows how threat identification and impact evaluation for interde-pendent critical infrastructures can be supported by two existing tools. The approach is illustrated with an example based on a run-ning EU project.
