What does network segmentation aim to achieve?

Network segmentation aims to improve security and performance by dividing a computer network into smaller, manageable segments. This practice limits the access of data and resources between various parts of the network, which enhances security by containing potential breaches. If one segment of the network is compromised, segmentation helps ensure that the threat does not easily spread to other segments, thereby protecting sensitive data and critical systems.

From a performance standpoint, segmentation can reduce congestion by limiting broadcast traffic, as only the devices within a given segment need to communicate with each other. By directing data traffic within more manageable sub-networks, organizations can achieve better overall network efficiency.

While enhancing software development, reducing data storage costs, and encouraging employee collaboration are important objectives within organizational operations, they are not the primary goals of network segmentation. Thus, focusing on security and performance is key in understanding the significant benefits that network segmentation provides.
