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.
