Which traffic zone refers to network traffic that occurs within a data center's security area?

The East-West Traffic Zone refers to network traffic that occurs within a data center's security area, typically involving communication between servers, applications, and other resources located within that same environment. This type of traffic is usually between internal services and does not traverse the external network, focusing on the interactions that happen laterally or horizontally across a data center.

Understanding the importance of the East-West Traffic Zone is critical for security, as it helps in implementing segmentation within the data center to minimize lateral movement of potential threats. By monitoring and controlling East-West traffic, organizations can enforce security policies more effectively, ensuring that sensitive data and resources are protected from unauthorized access and potential breaches that may occur from inside the network itself.

In contrast, the other types of traffic zones refer to different network interactions: North-South Traffic Zone deals with traffic flowing in and out of the data center to external users, while External Traffic Zone indicates traffic from outside the organization's network. Public Traffic Zone encompasses traffic that is accessible to the public internet, which emphasizes the exposure and risk associated with open access.
