Securing ASP.NET using OpenID Connect and IdentityServer
Today we are facing many authentication and authorization challenges regarding designing and developing modern applications. The requirements are more challenging than ever, especially when we need to support everything from mobile and SPA applications to micro-services in the cloud.
You can always use external services to manage users and their rights, but for those who want to manage this themselves, IdentityServer is a popular alternative. IdentityServer is an open-source framework for you who want to build your own identity service. In the course we mainly use IdentityServer, but we also look at how to use external services.
What you will learn
-
How OAuth and OpenID Connect works in detail
-
How to setup your own instance of IdentityServer
-
How to secure your ASP.NET Core applications using OpenID Connect and IdentityServer
When we go through these things, we will not just configure various magic libraries; instead we will take a look under the hood of OpenID Connect and IdentityServer to really understand what makes them tick.
In this course we use Visual Studio 2019, the latest ASP.NET Core 3 and IdentityServer 4. After you take this course, we highly recommend our course Web-Security for developers.
We recommend that you have a good computer that can run multiple instances of Visual Studio and at least one big monitor.
After this course, we recommend that you take a look at the course IdentityServer in Production where we will teach you how to create a real production ready setup of IdentityServer.
This course contains a lot of hands-on practical exercises where you will learn how to work with OpenID-Connect and the latest version of Duende IdentityServer.
