On April 11, 2023, we held our bi-yearly research update at the EDF site in Palaiseau. With almost the entire team of the chaire cyberCNI.fr present! As usual, the day was full of very nice presentations from our members, enriching discussions around our research topics, and of course open discussions around the cybersecurity. Thanks a lot to our hosts at EDF for the great hospitality, numerous expert participation, and the last but not least the very good food. We can all be proud of this wonderful day!
