Class of 2025
The 10th edition of the International Cyber Security Summer School took place from 17-22 August 2025. 52 students from over 15 countries participated in this six-day programme. The participants followed multidisciplinary lectures with a technical, legal, governance and social science view on different areas of cyber threats and opportunities. The lectures were provided by cybersecurity experts from public, private, and knowledge institutions. They covered various topics at the individual, organizational and governmental levels with varying aspects of developments in the world of (gen) AI and quantum cryptography, supply chain security and OT security.
Collaboration
During the International Summer School students took part in collaborative activities, such as the wargame on OT from Booz Allen Hamilton, a scenario planning workshop from Scenarios4 and a crisis simulation developed by and played out at NATO’s NCIA. Participants from diverse backgrounds and countries worked alongside each other to solve real-world cybersecurity challenges provided by HSD partners. They learned to incorporate diverse perspectives into their work, acquired new and honed their skills, and improved their ability of teamwork.
Innovative solutions to cybersecurity challenges
Throughout this week the students were given time to prepare and present solutions to challenges provided by aXite, Booz Allen Hamilton, Cyber resilience Center Greenport, Watchmen and Universiteit Leiden. The result was a collection of innovative solutions to real-world problems in the field of cybersecurity.
Onsite visits
During the International Cyber Security Summer School participants visited the headquarters of NATO Communications and Information Agency (NCI Agency) and Europol. During these visits students were given a taste of the security field through lectures a crisis management exercise, as well as the possibility to interact with different high-ranking experts in the field.
Connecting
Students were also able to get to know each other and connect during more informal moments as the BBQs at the beach, the campus lunches, the networking opportunities and the final drink to close ICSSS 2025 properly and say goodbye (or not) to fellow students and the participating partners who were also present. The world of cybersecurity is a growing, increasingly diverse and quickly developing world – a strong network within that community is vital.
