Zero Trust Architecture

"Zero Trust Architecture" is a definitive academic and practical guide to the most critical security paradigm of our time. It systematically deconstructs the traditional "castle-and-moat" security model and builds, from the ground up, a robust understanding of the Zero Trust principle: Never Trust, Always Verify. In an era defined by cloud computing, remote workforces, and the Internet of Things (IoT), the network perimeter has vanished. This book provides the essential knowledge to secure organizations where trust is no longer assumed based on location, but is continuously earned through rigorous verification.
