Azure API Management Security Tutorials

Explore these guides to enhance and secure your Azure API Management instances, ensuring robust protection for your APIs.

• Securing Your API with OAuth 2.0 and OpenID Connect

  Learn how to integrate OAuth 2.0 and OpenID Connect for user authentication and authorization in your API Management gateway.

  Authentication Authorization OAuth2 OpenID Connect
  # Example policy snippet for JWT validation <validate-jwt header-name="Authorization" require-expiry="true" require-signed-tokens="true" audience="YOUR_AUDIENCE" issuer="YOUR_ISSUER" />
• Implementing Rate Limiting and Quotas

  Discover how to protect your backend services from excessive traffic by implementing rate limits and usage quotas.

  Throttling Quotas Traffic Management
  <rate-limit calls="100" renewal-period="60" counter-key="@(context.Subscription.Key)" /> <quota remaining-calls-variable-name="remainingCalls" />
• Controlling Access with IP Filtering

  Configure IP filters to allow or deny access to your APIs based on the client's IP address.

  Access Control IP Filtering Network Security
  <ip-filter action="allow" ip="192.168.1.0/24"/> <ip-filter action="block" ip="10.0.0.1"/>
• Securing APIs with Client Certificate Authentication

  Implement mutual TLS authentication using client certificates for secure client-server communication.

  Mutual TLS Client Certificates Security
  <choose> <when condition="@(context.Request.Certificate == null || !context.Request.Certificate.Verify())"> <return-response> <set-status code="401" reason="Unauthorized"/> <set-body>Client certificate is required.</set-body> </return-response> </when> </choose>
• Advanced Security with Policy Expressions

  Leverage policy expressions for dynamic security rules, custom logic, and enhanced protection.

  Policies Custom Logic Expressions
  <set-header name="X-Request-ID" exists-action="override" value="@(Guid.NewGuid().ToString())"/>
