Zero Trust Security Engineering

The modern digital landscape demands a radical shift from traditional perimeter defenses, making Zero Trust security the essential framework for survival. This book provides a practical, engineering-focused guide to this model, establishing that security is an organizational responsibility.

The book systematically covers the Zero Trust Architecture and its six core pillars. You will learn to implement shift left security to protect your code and supply chain, and achieve network de-perimeterisation through effective segmentation. The book details protecting your most valuable asset, data, through encryption at rest and in transit, establishing continuous vulnerability management using tools (SCA, OSS), and maintaining operational integrity with SIEM-based continuous monitoring and incident response frameworks. Finally, it applies the framework to specialized contexts like container security and AI/ML models, concluding with strategies for managing complexity and ensuring compliance with global regulatory frameworks.

By the end of this book, you will gain a deep, risk-based mastery of the entire Zero Trust lifecycle. You will be fully equipped to design, implement, and govern highly secure systems, confidently managing technical tradeoffs and transforming your organization's security posture to thrive against advanced threats.

WHAT YOU WILL LEARN
● Implement the Zero Trust model across all application development stages.
● Secure coding practices to fortify your software supply chain.
