Overview of this book

Azure Active Directory for Secure Application Development is your one-stop shop for learning how to develop secure applications using modern authentication techniques with Microsoft Azure AD. Whether you’re working with single-tenant, multi-tenant, or line-of-business applications, this book contains everything you need to secure them. The book wastes no time in diving into the practicalities of Azure AD. Right from the start, you’ll be setting up tenants, adding users, and registering your first application in Azure AD. The balance between grasping and applying theory is maintained as you move from the intermediate to the advanced: from the basics of OAuth to getting your hands dirty with building applications and registering them in Azure AD. Want to pin down the Microsoft Graph, Azure AD B2C, or authentication protocol best practices? We’ve got you covered. The full range of Azure AD functionality from a developer perspective is here for you to explore with confidence. By the end of this secure app development book, you’ll have developed the skill set that so many organizations are clamoring for.

Each web-hosted resource that integrates with the Microsoft identity platform has a unique resource identifier, which is called the Application ID URI.

For example, here you can see a couple of web-hosted resources with their application ID URIs:

Third-party web-hosted resources that are registered in Azure AD also have an Application ID URI configured, and for each of these resources, you can also define a set of permissions. With these permissions...
