GRIFIN (ANR-20-CE39-0011 ) is a research collabora-tive project (PRC ) funded by the French National Research Agency (ANR). It started in April 2021 and ends in September 2025. It is led by T ́el ́ecom SudParis, and involves Université de Lorraine and Sorbonne Université. External advisory is provided by Montimage, a French SME, and British research centers at University College London and Middlesex Uni-versity London. A prototype of a resilience framework to protect IoT networks (TRL < 4) will be developed. Network state and the countermeasures’ impact to propose the best reaction? How can we characterize these impacts? Finally, the decoupling of the control and data planes in SDN involves an additional, overlooked, challenge: decisions taken at the control plane need to be conveyed to the data plane. How can we ensure that what is being enforced at the data plane actually fulfills what has been decided at the control plane? How can we reduce the semantic gap between the control and the data planes?
