What Is East-West Security?

November 7, 2023

East-west security refers to the security measures implemented on a data center’s east-west traffic, i.e., data transmissions conducted horizontally within the same network layer. The primary purpose of east-west security is to protect the data stored in the data center from lateral movement by bad actors that obtain access to a network segment.

The opposite concept, north-south security, deals with securing traffic between internal and external networks (e.g., the internet).
