Modeling extreme values resulting from compromising electromagnetic emanations generated by an information system

Electromagnetic intelligence and attacks pose unacceptable risks for the security and safety of critical networks and more specifically the power network. In this paper, it is pointed out how the use of the excess model allows one to extrapolate the very high level of spurious compromising emanations induced by an information system in realistic power network models. It is shown that the design of appropriate protections and risk management methodologies can be enhanced thanks to the extreme value statistics.
