What is the main goal of segmentation within a network?

The main goal of segmentation within a network is to improve network management. By dividing a larger network into smaller, manageable segments, an organization can enhance its ability to administer the network more efficiently. Each segment can be monitored and controlled independently, which allows for better allocation of resources, improved performance, and more effective troubleshooting.

Segmentation can also assist in applying security measures specific to each segment, thereby reducing the attack surface and localizing potential issues. This granular control enables administrators to enforce security policies more effectively, manage traffic flow, and configure virtual networks to meet varying operational needs without affecting the entire network's integrity.

Moreover, while improving data transfer rates and eliminating security threats are benefits that can be associated with effective network segmentation, the overarching goal remains focused on management enhancement. Expanding network capabilities, too, might be a side effect of better organization and management, but it is not the primary aim of segmentation itself.
