When the operational and technical context is in rapid evolution, and traditional computing methods are difficult to apply or are insufficient, how to proceed?
All experts agree that it is necessary to use a common sense approach which above all consists in mastering the components of an industrial information system, and to apply good practices leading to this. This includes system data flow charts, configuration and access management, or business continuity plan.
