Today was the final session of my teaching engagement in the new Master Cybersecurity program at IMT Atlantique in Rennes — and what an inspiring experience it has been.
Over the past weeks, I had the pleasure of teaching a fantastic group of students in our course on *Securing Critical Infrastructures*. With 8 female and 2 male students, the class brought together strong technical backgrounds, curiosity, critical thinking, and excellent discussions throughout the course.
We explored topics such as:
🔹 OT vs IT security
🔹 Industrial Control Systems (ICS)
🔹 Attack chains and cyber resilience
🔹 Security-by-design
🔹 Monitoring and anomaly detection
🔹 Human-centered cybersecurity
🔹 QUANTUMINSERT, Snowden, and the ethics of cybersecurity
For today’s final recap session before Friday’s exam, we connected all course topics into one big picture: how modern connectivity creates both enormous opportunities and major attack surfaces for critical infrastructures.
I was also very happy to invite two colleagues working with me on current cybersecurity projects:
🔹 Axel Dupraz presented hands-on demonstrations around real-world critical infrastructure cybersecurity challenges and operational exercises.
🔹 Fabien Eyssartier, working with me on the Horizon Europe project CyberSecDome, demonstrated next-generation cybersecurity interfaces and immersive approaches for future SOC environments. This led to fascinating discussions on usability, operator support, situational awareness, and human-centered cybersecurity.
One thing became very clear once again:
Cybersecurity is not only about technology. It is also about humans, communication, decision-making, resilience, and responsibility.
A huge thank you to all students for the excellent atmosphere, the energy, and the many thoughtful discussions throughout the course. Teaching becomes truly rewarding when students actively contribute their own perspectives and experiences.
Now only the written exam on Friday remains.
Good luck to all of you — and thank you for this great experience!
