Build a production-ready security system with ASP.NET Core, Identity, JWT Authentication, Roles, Permissions, and Clean Architecture. This Security Module is part of my complete Clean Architecture in .NET 10 course. The lessons are explained in Arabic, with English code and professional technical terminology. This is not just a collection of authentication tutorials. We build the complete security architecture step by step and explain the engineering decisions behind every component. You will learn: • Authentication vs Authorization • ASP.NET Core Identity and ApplicationUser • JWT generation, validation, claims, and signing • Register and Login workflows • Refresh Tokens and token revocation • Current User Context using JWT Claims • Roles vs Permissions • Permission-based authorization • EF Core security configurations and migrations • Idempotent permission seeding • Custom AuthorizationHandler • Dynamic Authorization Policies • Custom HasPermission Attribute • Protecting API endpoints with granular permissions • Clean Architecture boundaries and Dependency Inversion • Testing the complete security pipeline using Swagger The goal is to help you understand not only how to write the code, but how to design a scalable and maintainable security system like a software engineer.
