Secure ASP.NET Core Apps with Authentication and Authorization

Building secure web applications is a fundamental requirement for modern developers, yet setting up reliable security systems can feel overwhelming. This text-based course guides you step-by-step through the core concepts of securing your web applications using the built-in security features of ASP.NET Core. You will transition from writing unsecured endpoints to implementing robust, modern security architectures. By reading through our clear explanations and analyzing practical code examples, you will understand how to handle user registration, manage secure sessions, and restrict access based on user roles and custom policies. What you'll learn: Understand foundational security concepts including authentication, authorization, and secure password storage; Configure ASP.NET Core Identity to manage user registration, login, and logout flows; Implement cookie-based authentication for traditional web apps and token-based authentication with JWT for modern APIs; Apply role-based and policy-based authorization to restrict access to specific pages and endpoints; Practice securing applications against common vulnerabilities such as cross-site request forgery. The course starts with essential security terminology and configuration basics, then guides you through building a standard registration system, and concludes with policy-based authorization and modern API security techniques. This course is designed for beginner backend developers and web enthusiasts with a basic grasp of C# and web development, requiring no prior experience with application security.
