[Part 2] - Practice Azure services - Enhance security by using Key Vault and App Configuration ~ BỜM TẬP CODE

Scenario

In the previous post, we use a shared key to establish a connection to an Azure storage account (including Table storage and Blob storage) and SQL Database. This method can lead security vulnerabilities. To enhance the security of our application, we can leverage App Configuration along with Azure Key Vault. This post will illustrate how to integrate these services to our current application.

Let's started.

Overview architecture

The app now functions similarly to what was described in the earlier post. The difference is that we now save the connection string (shared key) for the storage account and SQL Database in Key Vault, and the configurations are managed in App Configuration instead of relying on the environment variables of Azure App Service. When the API starts up, it will load the configuration from an additional configuration provider, which is App Configuration, with the values sourced from Key Vault.
