welcome

This book is written for identity architects, application developers, product managers, and IT professionals who already have some experience with authentication and access control but want to explore the design and implementation of dynamic authorization more deeply. You don’t need to be an expert in policy languages or authorization engines, but a working knowledge of identity systems and basic software architecture will help you maximize the benefits of this book.

Dynamic authorization based on policies enables organizations to make access decisions in real-time, leveraging live data about people, devices, resources, and their connections. This approach moves beyond static roles and permissions, enabling fine-grained, just-in-time access that adapts as business needs evolve. It’s a major change, and it’s reshaping how systems are designed and managed.
