What is the main goal of using network segmentation?

The main goal of using network segmentation is to separate network traffic, which enhances both performance and security. By dividing a larger network into smaller, manageable segments or sub-networks, you can control the flow of data more effectively. This reduces congestion because broadcast traffic or heavy data transfers are confined to a specific segment, alleviating the overall load on the network.

From a security perspective, segmentation limits the exposure of sensitive data to only those segments that need access, thereby reducing the potential impact of security breaches. If an attacker gains access to one segment, it does not automatically give them access to other parts of the network.

This approach leads to improved management of network resources and allows for tailored security measures to be implemented in different segments based on their specific requirements. It also makes troubleshooting and monitoring more straightforward, contributing to an overall increase in operational effectiveness.
