Securing Blazor Applications with OIDC and Single Sign-On

Securing modern web applications is critical, yet configuring authentication flows can often feel overwhelming. If you want to protect your Blazor applications using industry-standard protocols, understanding how to implement robust security controls is the essential first step. This text-based course guides you through the foundational concepts of web security, focusing on OpenID Connect (OIDC) and Single Sign-On (SSO) within the Blazor ecosystem. You will transition from understanding basic security definitions to confidently configuring authentication middleware, securing application pages, and troubleshooting common integration issues. What you'll learn: - Understand the core principles of authentication, authorization, OIDC, and modern identity flows. - Configure secure middleware settings to establish seamless communication with external identity providers. - Implement Single Sign-On (SSO) to streamline the login experience across your applications. - Enforce page-level security and restrict access to unauthorized users using standard Blazor components. - Practice troubleshooting common configuration errors and token validation issues through structured written scenarios. - Apply modern security best practices, including secure token handling and managing authentication state changes. You will begin by exploring essential security terminology and foundational concepts before moving on to hands-on configuration files and code-based scenarios. The material progresses logically from initial setup to advanced page-level restrictions and debugging techniques. This course is designed for web developers new to application security and those looking to implement robust authentication in Blazor. No prior security experience is required, though a basic familiarity with C# and web development concepts is helpful.
