The Nord Stream explosion and the damage to submarine cables in the Baltic Sea and Red Sea have raised interest in seabed warfare all the world. And each country is preparing response plans and strategy. However, although South Korea relies on submarine cables for most of its internet network and is vulnerable to threats from North Korea and neighboring countries, even the term Seabed Warfare is unfamiliar. This paper is the first domestic study to analyze the definition and characteristics of seabed warfare, the current status of each country, and suggest countermeasures. In order to respond to seabed warfare, I propose establishing a cooperative system based on Mini-multilateralism between countries that share an international rules-based order, and establishing governance with related domestic organizations and companies. And I propose a military response plan based on deterrence by denial and deterrence by retaliation
