Zero Trust Networks: Building Secure Systems in Untrusted Networks 2nd Edition: 

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
