Set up an Azure app registration for the client app that calls the backend API.A simple Azure Function to act as our backend API secured by Azure AD.To demonstrate this scenario, let’s set up the following: To expose these APIs via APIM requires strategies around access restrictions and authentication on the inbound requests before it calls the backend APIs. Most often, the backend APIs are secured by Azure AD and we need to use OAuth 2.0 authentication and authorization to access the resource. Protecting API Operations With Azure AD and the validate-jwt Policy

(a full list of the policy reference can be found here). Many out-of-the-box policies can be configured and are generally grouped into categories such as access restriction, authentication, caching, cross-domain, transformation, etc.
To put it simply, policies are a bunch of rules and conditions that are applied by the APIM to the inbound requests and outbound responses of the backend APIs it manages. Policies are a collection of Statements that are executed sequentially on the request or response of an API. In Azure API Management (APIM), policies are a powerful capability of the system that allow the publisher to change the behavior of the API through configuration. In the official documentation, the APIM policies are defined as follows: Configure managed identity to authenticate with Azure Function.Protect API operations with Azure AD and the validate-jwt policy.What are Azure API Management policies?.I’m going to approach this topic in multiple posts, in this first post we are going to cover the following: In this post, we are going to delve into this particular topic and see how we can utilise Azure API management policies to further secure and restrict access to our backend APIs. One of the main questions that came up was around security, specifically around the topic of tightening access to backend APIs. If you use a SaaS solution, then it’s exposed.In my previous post, we discussed using Azure API Management (APIM) as the API gateway to expose the Cloud Flows with HTTP Request Trigger endpoints. Your self-hosted identity server doesn’t need to be exposed to the Internet, as it can live behind KrakenD and let the token generation requests be proxied through KrakenD. From here, let KrakenD sign the token for you and start using tokens right away. If you don’t have an identity server, you can still use your classic monolith/backend login system and adapt it to return a JWT payload (which is a simple JSON). KrakenD validates every incoming call’s signature, and it doesn’t make token introspection (asking the IdP data about the token owner). KrakenD does not need to validate all calls using your IdP. Still, you can plug it into any SaaS or self-hosted OpenID Identity Provider ( IdP) using industry standards (e.g., Auth0, Azure AD, Google Firebase, Keycloak, etc.) KrakenD does not generate the tokens itself. Protect endpoints from public usage by validating JWT tokens generated by any industry-standard OpenID Connect (OIDC) integration.īefore digging any further, some answers to frequently asked questions:
Supported hashing algorithms and cipher suites.Propagate JWT claims as request headers.Accepted providers for encrypting payloads.
