## Micro-Segmentation

Micro-Segmentation is a network security technique that divides the network into small, isolated zones to maintain separate security controls for each workload. In the context of a complex trading platform, this prevents an attacker from moving laterally across the infrastructure if they gain access to a single component.

By isolating the order matching engine from the wallet service or the public-facing website, platforms can limit the potential damage of a breach. Each segment has its own security policies, ensuring that only necessary communication is allowed between components.

This is a core element of Zero Trust Architecture, as it assumes that the network is already compromised and focuses on containment. Micro-segmentation is vital for protecting high-value assets and sensitive derivative data from sophisticated cyber-attacks that seek to traverse internal systems.
