For the last recent years, there has been a convergence between computer engineering approaches and automation aspects (industrial systems, internet of things) also called cyber-physical systems, for the development of process-based cyber-security strategies. Classically, security studies are based on risk analysis. Compared to classical IT approaches, the actual process (for instance a nuclear power plant or a chemical process) or system (autonomous car, drone) are taken into account in our approach for two reasons. The first reason is that the vulnerabilities of such systems or processes vary dynamically as a function of the time, the second reason is because the "standards" context is depending on the application domain and relationships with the IEC 61508 functional safety standard seems relevant. The paper presents a state of the art of problematics and proposed some approaches to these issues.
