Internet Basics (Part 2): Cable Landing Stations and Undersea Cables
Readiness training. LEA.Training does not grant any official certificate, licence or authority.
This lesson follows the internet into the sea. Most internet traffic between countries does not travel by satellite. It travels through undersea cables that come ashore at cable landing stations (CLS). Traffic means the data that moves across a network. This lesson explains both. It also explains why they matter to an investigation.
Focus: understand the physical path that global data takes. Know the questions it raises about lawful access and cooperation.
Learning objectives
- Explain what a cable landing station is and what it does.
- Describe what undersea cables are and how they carry data.
- Explain why this infrastructure matters for cross-border investigations.
