Within the Austrian national security research programme KIRAS, a study on security against electromagnetic threats was conducted. Apart from a survey on existing literature about respective events and analyses on existing threats and possible protection measures, a novel risk analysis method was developed, based on a qualitative FMEA (Failure modes and effects analysis). The traditional FMEA sheet was split into several tables taking advantage from the limited set of electromagnetic interference causes and a general set of high-level consequences. The resulting tables of risk priority numbers allowed a good overview on which defence and which protection measures should be prioritized. Finally, the method was validated based on three scenarios of road vehicle convoys with respect to its applicability. This paper describes the approach developed for the modified FMEA method and its application to three vehicle convoy scenarios, discussing the value of the method and interpreting the results of the validation.
