The world of data algorithmics with Computational Sciences is improving performance and productivity in several industrial sectors. The proliferation of sensors installed on complex systems found at every level of industry help both to fine-tune service in real time and to regulate all production sequences at the highest possible level. All stakeholders in the industry and society sectors are now up to speed with the digital age. Connected industry is hastening the pace of transformations that are already underway. But this comes at a price. All connected objects, soon to be linked to developments in Artificial Intelligence, are potential points of entry for digital attacks. Improved performance has the paradoxical effect of increasing exposure to cyber threats. Cyber attack can exploit the logics of networks, spreading to contaminate the most established industrial systems, such as social networks and governmental systems.
