ASP.NET Core and Angular BFF using a YARP downstream API protected using certificate authentication
This article demonstrates how to implement a downstream API protected by certificate authentication using Microsoft YARP reverse proxy in an ASP.NET Core web application. The application uses Angular for its UI and secures both the UI and the ASP.NET Core backend through a backend-for-frontend security architecture. The downstream API is secured with certificate authentication and […]
BFF secured ASP.NET Core application using downstream API and an OAuth client credentials JWT
This article shows how to implement a web application using backend for frontend security architecture for authentication and consumes data from a downstream API protected using a JWT access token which can only be accessed using an app-to-app access token. The access token is acquired using the OAuth2 client credentials flow and the API does […]
Implement a secure web application using Vue.js and an ASP.NET Core server
This article shows how to implement a secure web application using Vue.js and ASP.NET Core. The web application implements the backend for frontend security architecture (BFF) and deploys both technical stack distributions as one web application. HTTP only secure cookies are used to persist the session. Microsoft Entra ID is used as the identity provider […]
Secure Angular application using OpenIddict and ASP.NET Core with BFF
The article shows how an Angular nx Standalone UI hosted in an ASP.NET Core application can be secured using cookies. OpenIddict is used as the identity provider. The trusted application is protected using the Open ID Connect code flow with a secret and using PKCE. The API calls are protected using the secure cookie and anti-forgery […]
Secure Angular application using Auth0 and ASP.NET Core with BFF
The article shows how an Angular nx Standalone UI hosted in an ASP.NET Core application can be secured using cookies. Auth0 is used as the identity provider. The trusted application is protected using the Open ID Connect code flow with a secret and using PKCE. The API calls are protected using the secure cookie and anti-forgery tokens […]
Implement a secure web application using nx Standalone Angular and an ASP.NET Core server
This article shows how to implement a secure web application using Angular and ASP.NET Core. The web application implements the backend for frontend security architecture (BFF) and deploys both technical stack distributions as one web application. HTTP only secure cookies are used to persist the session. Microsoft Entra ID is used as the identity provider […]
Using Blazor with a YARP downstream API protected using certificate authentication
This article shows how to use a downstream API protected with certificate authentication using Microsoft YARP reverse proxy from a Blazor application. The Blazor WASM HTTP requests are sent to a secured backend which uses YARP to forward the requests to the API protected with the certificate authentication. The Blazor application authenticates using the OpenIddict […]
Implement a PWA using Blazor with BFF security and Azure B2C
The article shows how to implement a progressive web application (PWA) using Blazor which is secured using the backend for frontend architecture and Azure B2C as the identity provider. Code https://github.com/damienbod/PwaBlazorBffAzureB2C Setup and challenges with PWAs The application is setup to implement all security in the trusted backend and reduce the security risks of the […]
Comparing the backend for frontend (BFF) security architecture with an SPA UI using a public API
This article compares the security architecture of an application implemented using a public UI SPA with a trusted API backend and the same solution implemented using the backend for frontend (BFF) security architecture. The main difference is that the first solution is separated into two applications, implemented and deployed as two where as the second […]
Secure a Blazor WASM ASP.NET Core hosted APP using BFF and OpenIddict
This article shows how to implement authentication and secure a Blazor WASM application hosted in ASP.NET Core using the backend for frontend (BFF) security architecture to authenticate. All security is implemented in the backend and the Blazor WASM is a view of the ASP.NET Core application, no security is implemented in the public client. The […]
