“The regulation of critical infrastructure is an under-explored topic”
How do we protect society’s digital lifelines from sabotage and manipulation, —and what does the law say about this? These were some of the key questions addressed by lawyers, researchers, and security experts at the conference 'The Hybrid Battlefield of Fibre Optic Communication Cables'.

Fibre optic cables carry over 95 percent of all electronic communication worldwide. They are invisible to most of us, yet indispensable for everything from emails and video meetings to banking transactions and national security. At the same time, they are vulnerable to both physical sabotage and state surveillance.
“The cables are attractive targets for both intelligence services and malicious actors. This makes it essential to have an adequate legal framework governing the use and protection of this infrastructure,” explains .
Together with his colleagues and , Mella organized the conference hosted by the Faculty of Law on June 17.
Complex and Underexplored
Mella is a postdoctoral fellow at the Faculty of Law in Bergen, where he works on legal approaches to so-called hybrid threats. At a time of increasing geopolitical tension and technological complexity, he emphasizes that the law must keep pace with developments.
“The legal framework must clarify responsibilities, authorize measures, and set limits on state action. However, when it comes to securing fibre cables and bulk data collection, the law is complex and partly underexplored. That’s why we need more research and interdisciplinary insight,” he says
Shared Challenges – shared Solutions
The conference brought together 35 international participants from the public and private sectors and academia.
“Our aim was to create an arena for sharing knowledge and discussing the national and international regulation of this critical digital infrastructure. For both academic and practical reasons, it is urgent to address the questions that arise in this context”, Mella continues.
The conference highlighted that many of the challenges are shared across national borders, and that the approaches to solving them are often similar.
“It was interesting to see how comparable countries have adopted quite similar approaches to both securing cables and regulating state bulk data collection from them. This provides a solid foundation for further research and collaboration in the years to come,” says Mella.
