SINGAPORE: Defence officials from Europe and South-East Asia called for stronger collaboration to protect the global network of subsea cables as concerns grow over threats to this vital infrastructure.
Countries such as Singapore and Malaysia are becoming key hubs for the roughly 600 fibre-optic cables that carry nearly all of the world’s data. Meanwhile, a spike in cable damage in European waters, particularly in the Baltic Sea, has heightened fears about the network’s vulnerability.
“We need to work together to defend the entire network,” Singapore Defence Minister Chan Chun Sing said at the IISS Shangri-La Dialogue security forum on Sunday. “There’s no point trying to defend the integrity and security of a submarine cable by looking at a point. We need both ends to be secure.”
The issue came up repeatedly during the two-day summit in Singapore, with European officials keen to share what they’ve learned from the recent rise in subsea cable damage. Today, the global undersea cable network stretches about 1.4 million kilometres.
With the demand for data centre power projected to surge significantly with the advent of intensive AI platforms, more cables are essential. Protecting them has become a key imperative in Europe since Russia’s full-scale invasion of Ukraine, with incidents in its waters mostly involving tankers traveling to and from Russia, and in at least one case, a Chinese vessel.
A rise in the sale of subsea cable systems could see investment reach US$15.4 billion between 2024 and 2028 as data centre construction booms, connectivity needs soar and the role of big tech companies expands in the market, according to Bloomberg Intelligence.
Despite suspicions of sabotage, there’s been no strong evidence pointing to deliberate attacks, with the incidents more likely to be accidents or careless behaviour. Still, NATO countries have increased patrols in key areas to ensure the safety of undersea infrastructure.
The European Union’s top diplomat Kaja Kallas urged European and Asian partners to work together at sea to tackle covert “shadow fleets” of tankers and review maritime security laws.
Protecting digital cable infrastructure is important for the Philippines too, Defence Secretary Gilberto Teodoro said in an interview. He added that his country, which is locked in a long-running dispute with China in the South China Sea, is working to build up its capabilities to address the threat.
Thailand also called the issue a pressing concern, with Defence Minister Phumtham Wechayachai saying the country is collaborating with Singapore and Brunei. He added, undersea infrastructure faces risks not only from sabotage, but also from accidents and natural disasters. – Bloomberg

The escalating importance of subsea cables, the backbone of the internet, has solidified its position as a crucial focus of global security discussions.Recent calls for enhanced international cooperation reflect a growing awareness of the vulnerabilities inherent in this vital infrastructure.As the world’s reliance on data transmission soars, safeguarding these submerged lifelines becomes increasingly paramount. The discussions at the IISS Shangri-La Dialog highlighted not just the technical aspects, but also the geopolitical ramifications of securing these digital arteries.
The Geopolitics of data: A Shifting Landscape
The increasing interconnectedness of the world, driven by the insatiable demand for data, has put the spotlight on the physical infrastructure that facilitates this exchange. Subsea cables,frequently enough described as the internet’s nervous system,are facing heightened scrutiny due to their strategic importance. Any disruption, whether accidental or malicious, can have far-reaching consequences, disrupting financial markets, communications, and critical national infrastructure. The implications are vast, especially as data-hungry technologies and AI continue to evolve.
The Baltic Sea incidents, coupled with activities in the South China Sea, underscore the complex web of actors and interests involved. Accusations and investigations surrounding cable damage, further complicate the situation, highlighting the need for robust international cooperation and details-sharing mechanisms.
Enhancing collaboration and Resilience
The call for stronger collaboration among nations is a direct response to the growing threats. Coordinated patrols, information sharing, and the progress of common security protocols are key elements of a comprehensive strategy. This approach moves beyond individual national interests, promoting a collective defense of the entire network. As the demand for data transmission climbs, the necessity for comprehensive proactive protection becomes increasingly critical.
The increasing importance of regional partnerships is highlighted by Thailand’s commitment and the Philippines’ efforts to improve their defensive capabilities. Countries are actively exploring ways to reinforce the resilience of the underwater cable network, working together to ensure a swift reaction to any threat.

FAQ: Undersea Cable Security
This section offers clear and concise answers to the most frequently asked questions about the state of undersea cable security, answering popular queries.
What are Subsea Cables?
Subsea cables are thick fiber-optic cables laid on the seabed, connecting continents and islands, and enabling the vast majority of global internet traffic, phone calls, and data transmission. they are the critical arteries of the internet, handling over 99% of the world’s transoceanic data.
Where are Subsea Cables located?
These cables are strategically placed on the ocean floor, connecting various locations worldwide. Key hubs include coastal regions, with extensive networks in areas such as Southeast Asia, Europe, and North America. The precise routes are often confidential for security reasons, but the overall infrastructure spans across all major oceans and seas.
How are Subsea Cables protected?
Protection involves a combination of physical safeguards, surveillance, and international collaboration. These safeguards include: burying cables in shallower waters, specialized cable coatings, monitoring equipment for detecting anomalies, patrols of sensitive areas, and collaborative agreements between nations to share information and coordinate responses to threats.
Who is responsible for protecting subsea cables?
Multiple parties share duty. Governments are responsible for maritime security,while cable owners (often telecommunications companies) manage and maintain the physical infrastructure. International collaboration and information sharing are critically crucial.
What happens if a subsea cable is damaged?
Damage can result in disruption of internet services, dialogue outages, and economic impacts. Repair involves locating the damaged section, deploying specialized ships to retrieve and repair the cable, and restoring connectivity, which can take days or weeks, depending on damage.
What are some threats to subsea cables?
Threats include accidental damage from ships and fishing activities, natural disasters (earthquakes and tsunamis), sabotage (intentional acts of damage), and potential cyberattacks.There are also concerns about the intentional targeting of critical infrastructure in geopolitical conflicts.
what role do countries play in securing subsea cables?
Countries play a crucial role in many ways, including deploying maritime patrol forces, enacting and enforcing maritime security laws, sharing intelligence on potential threats, and engaging in international collaborations focused on protecting critical infrastructure. Bilateral and multilateral agreements are essential for coordinating responses to cable security incidents. They are responsible for protecting their territorial waters and coordinating efforts with cable operators and other nations to ensure the security of these critical assets.
How are emerging technologies affecting undersea cable security?
Emerging technologies, such as AI and advanced sensors, are improving the detection and response to threats. The growth of Internet infrastructure expands the scope to monitor submarine cables. AI can analyze vast datasets for the better identification of vulnerabilities and potential attack patterns. Other technologies, such as the expanding use of drones and autonomous underwater vehicles (AUVs), enable enhanced surveillance and also repair capabilities, improving overall cable security.
