在解决超出法定暴露限制的EMC问题时，故意电磁干扰(IEMI)一词指的是故意试图扰乱电子设备的正常运行，从单个设备到支持社会基本流程的关键基础设施等大型系统。在试图评估后者的整体脆弱性并确定用于保护措施的资源的优先次序时，调查系统易感性的技术方面必须辅之以更广泛的跨学科风险管理或复原力评估方法。承认EMC领域已经提出的方法，我们讨论了基于欧盟项目SmartResilience中阐述的指标的复原力评分的概念。在数百个指标中，有十几个评价处方包含在与IEMI威胁有关的项目数据库中。在概述了一般项目方法之后，讨论了一个通用电网变电站的示范性评估，并与其他方法进行了比较。虽然使用可获得的指标可以轻松地进行评估，因此甚至可以扩展到大型分布式系统，但重点方法实现了更深入的评估，这反过来又需要专家的广泛努力。
Addressing EMC issues beyond legal exposure limits, the term of intentional electromagnetic interference (IEMI) designates deliberate attempts to disrupt normal operation of electronics, from single devices up to large systems like critical infrastructures sustaining fundamental processes in society. When trying to assess the overall vulnerability of the latter and prioritising resources for protective measures, investigating the technical aspects of system susceptibility will have to be complemented with broader, interdisciplinary methodology for risk management or resilience assessment. Acknowledging approaches already suggested within the field of EMC, we discuss the concept of resilience scoring based on indicators as elaborated within the EU project SmartResilience. Among hundreds of indicators, a dozen evaluation prescriptions are included in the project database pertaining to the IEMI threat. After outlining the general project methodology, an exemplary assessment of a generic power grid substation is discussed in comparison with other approaches. While using accessible indicators enables easily performed assessments and thus scales even to large, distributed systems, more depth is achieved by the focused methods in turn requiring extensive efforts by experts.
