The management and protection of these SCADA systems must constantly evolve towards integrated decision making and policy driven by cyber security requirements. The current research stream in this domain aims, accordingly, to foster the smartness of the field equipment which exist through the generic concept of SCADA management and operation. Those components are governed by policies which depend on the components roles, as well as on the evolution of the crisis which also confer to the latter the latitude to react based on their own perception of the crisis evolution. Their latitude is calculated based on the component smartness and is strongly determined by, and depending on, the cyber safety of the component environment. Existing work related to crisis management tends to consider that components evolve and are organized in systems but as far as we know, no systemic solution exists which integrates all of the above requirements. This paper proposes an innovative version of ArchiMate® for the SCADA components modelling purpose to enrich their collaborations and, more particularly, the description of their behavior endorsed in the cyber-policy. Our work has been illustrated in the frame of a critical infrastructure in the field of petroleum supply and storage networks.
