Securing APIs using ASP.NET Core and OAuth 2.0 DPoP
This article shows how an ASP.NET Core application can access an ASP.NET Core API using OAuth Demonstrating Proof-of-Possession (DPoP). This is a really powerful security enhancement which is relatively easy to support. The access tokens should only be used for what the access tokens are intended for. OAuth DPoP helps force this. This solution was […]
Application security context models
This article looks at a new concept for creating application security context models for modern solutions using best practice security. By using security context models in projects, a qualitative and secure authentication solution can be produced quicker and more efficient. At present, too many solution architects try to patch the security architecture after the application […]
Provision Azure IoT Hub devices using DPS and X.509 certificates in ASP.NET Core
This article shows how to provision Azure IoT hub devices using Azure IoT hub device provisioning services (DPS) and ASP.NET Core. The devices are setup using chained certificates created using .NET Core and managed in the web application. The data is persisted in a database using EF Core and the certificates are generated using the […]
Use multiple identity providers from a Blazor WASM ASP.NET Core App secured using BFF
This post shows how to implement a Blazor WASM UI hosted in an ASP.NET Core application using multiple identity providers to authenticate. Two confidential OpenID Connect code flow clients with PKCE are used to implement the Blazor authentication. The Blazor WASM and the ASP.NET Core application are a single security context. This is implemented using […]
