Our study for the European Parliament on the vulnerabilities of the EU’s subsea data cable infrastructures is now published. The report is available here. It analyses the state of the EU cable system, identifies threat scenarios, and lays out a series of recommendations of how the EU and its member states can enhance resilience. Here is the abstract:

The EU’s subsea data cable network is both vital for global connectivity and vulnerable. This study provides a systematic review of the current security threats, as well as the actors at the origin of these threats. Building on reports and expert input, the paper takes stock of current awareness, preparedness and response mechanisms, both at the EU and Member State level. A number of recommendations suggest how to improve the resilience of the cable network. Proposals build on the need to enhance EU-wide awareness, improve coordination and share information across EU institutions and Member States. In addition, surveillance capabilities must be advanced, response and repair mechanisms strengthened, and the topic mainstreamed across external action.
