Backend Security and Authentication with ASP.NET Core

Securing backend applications is one of the most critical responsibilities of a modern developer. Building robust authentication systems ensures that sensitive user data remains protected against evolving digital threats.\n\nThis text-based course guides you through the core principles of backend security using ASP.NET Core. You will progress from understanding fundamental cryptographic concepts to implementing production-ready authentication and authorization workflows, including modern AI-assisted secure coding techniques.\n\nWhat you'll learn:\n- Understand foundational security concepts, encryption standards, and threat landscapes\n- Configure ASP.NET Identity to manage user registration, login, and password hashing\n- Implement role-based and policy-based authorization to restrict access to sensitive endpoints\n- Apply data protection APIs to securely encrypt and decrypt application data\n- Utilize AI assistants to write secure, vulnerability-free backend code\n- Incorporate token-based authentication and zero-trust concepts into your API design\n\nThe course begins with essential security definitions and architectural concepts before moving into step-by-step configurations of identity systems. You will then explore advanced authorization strategies, data encryption, and best practices for securing API endpoints.\n\nThis course is designed for beginner backend developers and software engineers looking to establish a solid foundation in application security. No prior security experience is required, though basic familiarity with C# and web development is helpful.\n\nStart reading today to build secure, resilient backend applications with confidence.
