Microsoft Entra ID for Microsoft 365: Master Identity, Authentication, Security Policies, and Enterprise Access
Modern cybersecurity begins with identity.
As organizations increasingly adopt Microsoft 365, identity has become the foundation of secure collaboration, cloud administration, application access, and enterprise governance. Microsoft Entra ID is no longer just a directory service-it is the central identity platform that protects users, devices, applications, and business data across the Microsoft cloud.
Microsoft Entra ID for Microsoft 365 is a comprehensive, production-focused guide designed to help IT professionals build, secure, automate, and operate enterprise identity environments with confidence. Rather than focusing on isolated features or portal walkthroughs, this book takes a practical, architecture-first approach that mirrors how Microsoft Entra ID is implemented and managed in real organizations.
Starting with the fundamentals of identity architecture, you'll progress through authentication, Conditional Access, identity governance, privileged access management, Microsoft Graph automation, hybrid identity, Microsoft 365 integration, and enterprise-scale operations. Along the way, you'll work through realistic production scenarios, complete PowerShell and Microsoft Graph examples, and detailed case studies based on the challenges faced by modern enterprise IT teams.
Inside this book, you will learn how to:
