Which of the following is a fundamental concept of network segmentation?

Network segmentation is primarily concerned with dividing a larger network into smaller, manageable, and isolated segments. One of the fundamental concepts associated with this practice is enhanced security. By segmenting a network, you can limit the exposure of sensitive data and critical systems to potential threats. Each segment can have its own security measures and controls, reducing the likelihood that a breach in one segment will affect others. For instance, if an attacker gains access to one segment of the network, they may not easily progress to another segment if proper segmentation is in place. This creates barriers that help protect sensitive data and resources more effectively.

While improved throughput, data redundancy, and cost reduction can be benefits associated with specific networking strategies or configurations, they are not the primary focus of network segmentation. Enhanced security stands out as the driving force for implementing network segmentation, making it a critical concept in network design and security architecture.
