Which of the following statements best describes 'Segmentation'?

Segmentation refers to the practice of grouping network resources into isolated areas to enhance security and efficiency within a network. This technique allows for distinct segments or zones with defined boundaries, which can help contain potential breaches, limit access to sensitive resources, and improve overall network performance. By isolating different parts of a network, organizations can better control traffic, apply specific security policies to various segments, and reduce the risk of an attack spreading across the entire infrastructure.

This isolation can be achieved through various means, such as implementing Virtual Local Area Networks (VLANs), firewalls, or physical separation of network segments. Each segment can be tailored with its own security measures, ensuring that sensitive data remains protected while allowing necessary access to other parts of the network.

The concept of segmentation is a fundamental principle in cybersecurity practices, significantly contributing to the overall defense in depth strategy, which is intended to mitigate risks by adding multiple layers of security.
