How we handled a major increase in our threat landscape
2025-10-31 , Main Stage

In May of 2024 an announcement was made: The NATO Summit of 2025 would take place at The Hague. Little did we know about what that would mean for our organization and for our city. In this talk, Lilian will talk you through our security preparation and our efforts during those two days of the summit.


Ofcourse we can only disclose information labeled TLP:GREEN by our partners, and our own information and experiences on how we handled 1) preparing and 2) the Summit taking place. For part 1 (preparations) I will share how we handled our increased threat landscape (with a threat assessment), how we defined our security measures using a threat assessment and how we prepared our organization with cybercrisis exercises. For part 2 (the Summit itself) I will share our experiences from the eyes of the information coordinator role in the cyber backoffice. I will only share our goal, roles and collaborations.
I’ll end with the remaining question: and now what?
