摘要：AbstractThis paper attempts to summarize information related to ensuring system resilience across disciplines. The first part outlines the reasons why the security in current systems is inadequate, generating the need to deepen the knowledge of the second generation of safety (Safety II). The authors also compare the views on safety from the perspectives of the current methods and resilience. Further, the paper also discusses the basic features required for a resilient system and presents the ideal definition of such a system. The final analysis then characterizes the methods to be applied in ensuring the resilience of industrial systems; importantly, this section also provides an example of how the current security scenarios can fail in high complexity systems. In this context, the demands on an industrial resilient control system are outlined, together with how the second generation safety approaches differ from the previously applied concept.
