What is the purpose of network segmentation?

The purpose of network segmentation is to improve performance and security by dividing a network into smaller parts. This approach allows for better management of data traffic, reduces congestion, and enhances overall network efficiency. When networks are segmented, it can limit the impact of broadcast traffic, which helps to optimize bandwidth usage.

From a security perspective, segmentation creates boundaries within the network, which can help contain any potential security breaches or attacks. By isolating segments, sensitive data can be better protected, and access controls can be implemented to restrict which devices can communicate with each other, thereby minimizing the attack surface.

Dividing a network also allows for more granular monitoring and management of traffic, which can lead to quicker identification of issues and enhanced troubleshooting capabilities. Overall, network segmentation is a crucial strategy employed to enhance both performance and security within modern network infrastructures.
