Externalizing authorization logic for application APIs can yield multiple benefits for Amazon Web Services (AWS) customers. These benefits can include freeing up development teams to focus on application logic, simplifying application and resource access audits, and improving application security by using continual authorization. Amazon Verified Permissions is a scalable …

Enterprises often have an identity provider (IdP) for their employees and another for their customers. Using multiple IdPs allows you to apply different access controls and policies for employees and for customers. However, managing multiple identity systems can be complex. A unified authorization layer can ease administration by centralizing …

As you design your Amazon API Gateway applications to rely on mutual certificate authentication (mTLS), you need to consider how your application will verify the revocation status of a client certificate. In your design, you should account for the performance and availability of your verification mechanism to make sure …

As Amazon Web Services (AWS) customers build new applications, APIs have been key to driving the adoption of these offerings. APIs simplify client integration and provide for efficient operations and management of applications by offering standard contracts for data exchange. APIs are also the front door to hosted applications …

In this blog post, we will show you how to use Amazon Elastic Load Balancing (ELB)—specifically a Network Load Balancer—to apply a more granular control on the cipher suites that are used between clients and servers when establishing an SSL/TLS connection with Amazon API Gateway. The …

Authorizing functionality of an application based on group membership is a best practice. If you’re building APIs with Amazon API Gateway and you need fine-grained access control for your users, you can use Amazon Cognito. Amazon Cognito allows you to use groups to create a collection of users …

Last year Amazon API Gateway announced certificate-based mutual Transport Layer Security (TLS) authentication. Mutual TLS (mTLS) authenticates the server to the client, and requests the client to send an X.509 certificate to prove its identity as well. This way, both parties are authenticated to each other. In a …
