Reference configurations for the characterization of critical infrastructures

Intentional electromagnetic interference arises to be a threat to critical infrastructures. These infrastructures are increasingly reliant on the proper functioning of electronic systems. An interference of such systems can lead to a tremendous damage both physically and financially. For the protection and hardening of infrastructures, their subsystems and functions need to be assessed. However, each infrastructure is built specifically so that a comprehensive assessment is not possible. In order to enable an assessment of the infrastructures, in this paper, a basic reference configuration is derived based on existing standards. This reference configuration will be applied to chosen examples of critical infrastructures. The differences and similarities of the critical subsystems of the infrastructures will be pointed out.
