Zero Trust, Real World: Identity at the Center

As digital environments grow more complex and perimeter-based security models continue to fail, organizations must rethink how trust is established and maintained. Zero Trust, Real World: Identity at the Center delivers a practical, modern approach to cybersecurity by placing identity at the heart of every access decision.
This book explains why implicit trust is the root cause of many modern breaches and how Zero Trust principles eliminate these weaknesses through continuous verification. It explores how users, devices, applications, and data should be authenticated and authorized in real time, reducing the risk of credential misuse, lateral movement, and insider threats. Rather than focusing on theory alone, the book connects Zero Trust concepts to real-world implementation challenges.
Inside this book, readers will learn:
• Why identity is the foundation of modern security architecture
• How Zero Trust differs from traditional perimeter-based models
• How to design secure access across cloud, hybrid, and on-prem systems
• How continuous authentication reduces breach impact
• How to align Zero Trust strategies with business productivity
Written in a clear, structured, and practical style, this book is ideal for students, cybersecurity professionals, IT architects, and technology leaders. It equips readers with the mindset and strategies needed to design resilient security systems where identity truly sits at the center of trust.
