The implementation of network segmentation in a Kubernetes cluster helps to:

Control communication between containers

The implementation of network segmentation in a Kubernetes cluster primarily helps to control communication between containers. By segmenting the network, administrators can create distinct zones within the cluster, each with its own set of rules governing how and when components (such as pods and services) can communicate with each other. This approach allows for finer control over network traffic, enhancing security and compliance by limiting exposure to sensitive services and providing a means to implement specific policies tailored to various workloads.

In a segmented network scenario, you can enforce access policies that only permit necessary communication paths. This helps in mitigating risks such as unauthorized access and reduces the potential attack surface within the cluster. Thus, network segmentation is a critical practice for maintaining a secure and well-structured Kubernetes environment.
