auth-policies

Policy-based authorization in ASP.NET Core is implemented by defining custom IAuthorizationRequirement and IAuthorizationHandler pairs, registering a dynamic policy provider in DI, and applying permission attributes to endpoints.

Resource-based authorization in .NET applications is enforced by implementing resource ownership checks that restrict actions to the correct authenticated user, applicable across API endpoints and controllers.

JWT claims can be used for dynamic permission policies in .NET minimal APIs by mapping permission constants to a dynamic policy provider and applying a HasPermission attribute to enforce access control.

Centralizing authorization logic across enterprise .NET apps is best achieved using a policy-based approach with custom requirements, database-backed permissions, and dynamic policy provisioning for consistent access control.

This policy-based authorization approach supports database-backed permissions alongside JWT claims by mapping permission constants through a dynamic policy provider registered in dependency injection.

A dynamic policy provider is used instead of static authorization policies in .NET to automate policy creation for permission-based access, preventing hardcoded policy registration for every permission constant.
