What does network segmentation aim to achieve?

Network segmentation aims to enhance security and performance by dividing a larger network into smaller, isolated sub-networks or zones. This separation allows for more effective control and monitoring of each segment, enabling specific security policies, access controls, and monitoring to be applied based on the needs of that segment. For instance, sensitive data might be kept on a highly secure segment with strict access controls, while less critical operations could be placed in a more open segment.

This strategy not only improves security by containing potential breaches to a smaller zone, but it also enhances overall network performance by reducing congestion and managing traffic flow more efficiently. By enabling different segments to be controlled and monitored individually, organizations can better respond to incidents and manage compliance with security policies, making segmentation a crucial aspect of network architecture and security strategy.
