This module explores the evolution from traditional perimeter-based security to modern Zero Trust Architecture (ZTA). You will learn the principles of network segmentation, the shift to workload-level microsegmentation, and how identity-based access controls replace implicit trust. From a cybersecurity perspective, flat networks allow attackers to move laterally with ease once they breach the perimeter. You will discover how defenders use Zero Trust principles—never trust, always verify—to contain breaches, enforce least-privilege access, and secure workloads across hybrid cloud and on-premises environments.
