Security Term

Network Segmentation

The practice of dividing a computer network into smaller subnetworks to contain security breaches and limit the blast radius of attacks.

What is Network Segmentation?

By isolating critical systems, databases, industrial controls, or sensitive user data, network segmentation ensures a compromised device cannot freely communicate with the rest of the network. It is a fundamental control in zero trust architectures and regulatory compliance frameworks.

Understanding this concept is crucial for maintaining a robust security posture. In the context of modern cyber threats, network segmentation represents a significant area of focus for security professionals and organizations alike.
