Abstract: A method of executing a request to an industrial control system, which runs in a protected domain and is configured to control one or more field devices. Each step of the method is to be executed on processing resources of a cloud domain (CD), an edge domain (ED) or the protected domain. According to the first aspect, a step of receiving, from a client, a message with a request containing logical actions and a step of authenticating the client are performed using CD resources. Next, a step of initiating a verification of the message and a step of checking whether the authenticated client is authorized to perform the logical actions are performed using ED resources. Then, a step of mapping the logical actions to physical actions and a step where the industrial control system is caused to execute the physical actions are performed using resources in the protected domain.
