Claims-Based Authentication and Authorization in ASP.NET Core

Building secure web applications requires a robust understanding of how to identify users and control what they can access. Claims-based security offers a flexible, modern approach to managing identity and permissions in the .NET ecosystem. In this text-based course, you will transition from basic security concepts to implementing sophisticated claims-based authentication and authorization, gaining the confidence to design secure applications that protect sensitive data. What you'll learn: - Understand the foundational concepts of identity, claims, authentication, and authorization. - Configure cookie-based authentication for traditional web applications. - Implement JSON Web Tokens (JWT) to secure APIs and modern client-server architectures. - Create custom authorization policies to enforce complex business rules. - Integrate claims-based security with modern ASP.NET Core Minimal APIs and MVC. - Apply best practices for token validation, security headers, and modern threat mitigation. The course starts with essential security definitions and architectural basics before guiding you through step-by-step implementation patterns for both MVC and modern API endpoints. You will learn entirely through clear written explanations and practical code examples. This course is designed for beginner to intermediate developers looking to establish a solid foundation in web security, with no prior security experience required.
