Zero Trust Networks

This practical book provides a detailed explanation of the zero trust security model. Zero trust is a security paradigm shift that eliminates the concept of traditional perimeter-based security and requires you to always assume breach and never trust but always verify. The updated edition offers more scenarios, real-world examples, and in-depth explanations of key concepts to help you fully comprehend the zero trust security architecture. * Examine fundamental concepts of zero trust security model, including trust engine, policy engine, and context aware agents * Understand how this model embeds security within the system’s operation, with guided scenarios at the end of each chapter * Migrate from a perimeter-based network to a zero trust network in production * Explore case studies that provide insights into organizations’ zero trust journeys * Learn about the various zero trust architectures, standards, and frameworks developed by NIST, CISA, DoD, and others
