Fighting a Digital Blockade: View from Taiwan
Taiwanese digital affairs officials and experts discuss digital blockade scenarios, undersea infrastructure protection, and cyber-resilience against nation-state threats.
Summary
The Threat of Digital Blockades
Island nations and isolated territories face unique cybersecurity risks from potential digital blockades, where adversaries combine physical sabotage of communications infrastructure with large-scale cyber disruptions to sever external connectivity.
Undersea Cable Vulnerabilities and Sabotage
Undersea fiber-optic cables represent critical chokepoints for international data traffic. Physical tampering, anchor-dragging incidents, and coordinated subsea disruptions threaten to isolate national communication networks during geopolitical conflicts.
National Cyber Resilience Strategies
Defending against digital blockades requires building multi-layered communication redundancy, incorporating low Earth orbit satellite constellations, decentralized domestic routing, and hardened emergency backup networks.
International Coordination and Policy Frameworks
Securing subsea infrastructure demands cross-border partnerships, shared maritime threat intelligence, and international legal frameworks to deter and respond to attacks on critical communication arteries.
