Description: Network segmentation is the practice of dividing a computer network into smaller parts, known as segments, with the aim of improving both performance and security. This technique allows devices within a segment to communicate with each other more efficiently, reducing congestion and enhancing data transmission speed. Additionally, by isolating segments, the reach of potential cyberattacks is limited, as an intruder who gains access to one segment cannot easily move to other segments without proper authorization. Network segmentation also facilitates the management of security policies, allowing specific controls to be applied to each segment according to their needs. In general, network segmentation is a strategy for optimizing network performance and enhancing security in various network environments.
