Securing SignalR Chat in ASP.NET Core

Real-time chat applications require robust security to prevent unauthorized access to sensitive conversations. Building a chat channel with SignalR is only the first step; securing it with modern authentication protocols is essential for production-ready applications. This text-based course guides you through the process of securing real-time web applications. You will learn how to integrate industry-standard security protocols to verify user identities and restrict channel access. What you'll learn: - Understand the core concepts of real-time communication security and SignalR hub protocols. - Configure JSON Web Token (JWT) authentication to validate user identities securely. - Implement OpenID Connect (OIDC) flows to delegate authentication to trusted identity providers. - Apply authorization policies to restrict access to specific chat channels and hubs. - Practice handling token expiration and secure connection handshakes in real-time environments. - Learn modern ASP.NET Core security best practices, including safe token storage and minimal API authentication. Starting with fundamental security definitions and SignalR basics, the course walks you through step-by-step configuration files, middleware setup, and authentication handlers. This course is designed for beginner to intermediate developers looking to secure their ASP.NET Core applications. No prior experience with web security is required, though basic familiarity with C# is helpful. Start reading today to build secure, real-time chat features with confidence.
