Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 517 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional SAP-C02
Question #: 517
Topic #: 1
[All AWS Certified Solutions Architect - Professional SAP-C02 Questions]

A company is using AWS to develop and manage its production web application. The application includes an Amazon API Gateway HTTP API that invokes an AWS Lambda function. The Lambda function processes and then stores data in a database.

The company wants to implement user authorization for the web application in an integrated way. The company already uses a third-party identity provider that issues OAuth tokens for the company’s other applications.

Which solution will meet these requirements?

  • A. Integrate the company’s third-party identity provider with API Gateway. Configure an API Gateway Lambda authorizer to validate tokens from the identity provider. Require the Lambda authorizer on all API routes. Update the web application to get tokens from the identity provider and include the tokens in the Authorization header when calling the API Gateway HTTP API.
  • B. Integrate the company's third-party identity provider with AWS Directory Service. Configure Directory Service as an API Gateway authorizer to validate tokens from the identity provider. Require the Directory Service authorizer on all API routes. Configure AWS IAM Identity Center as a SAML 2.0 identity Provider. Configure the web application as a custom SAML 2.0 application.
  • C. Integrate the company’s third-party identity provider with AWS IAM Identity Center. Configure API Gateway to use IAM Identity Center for zero-configuration authentication and authorization. Update the web application to retrieve AWS Security Token Service (AWS STS) tokens from IAM Identity Center and include the tokens in the Authorization header when calling the API Gateway HTTP API.
  • D. Integrate the company’s third-party identity provider with AWS IAM Identity Center. Configure IAM users with permissions to call the API Gateway HTTP API. Update the web application to extract request parameters from the IAM users and include the parameters in the Authorization header when calling the API Gateway HTTP API.

Selected Answer: A
By integrating the third-party identity provider with API Gateway and using a Lambda authorizer to validate OAuth tokens, Option A provides a seamless and integrated solution for user authorization in the web application, while leveraging the company's existing identity management infrastructure. The other options have drawbacks or do not fully meet the requirements: Option B: Integrating with AWS Directory Service and configuring it as an API Gateway authorizer may be unnecessary since the company already has a third-party identity provider. Option C: Requiring the web application to retrieve AWS STS tokens may be unnecessary since the company already has OAuth tokens issued by the third-party identity provider. Option D: Creating IAM users and extracting request parameters can be more complex and may not leverage the existing third-party identity provider and OAuth token issuance process.

Selected Answer: A
Building a Lambda authorizer allows users to access API Gateway resources by using their third-party credentials without having to configure additional services, such as Amazon Cognito. This can be particularly useful if your organization is using the third-party identity provider for single sign-on (SSO). on.com/blogs/security/use-aws-lambda-authorizers-with-a-third-party-identity-provider-to-secure-amazon-api-gateway-rest-apis/

A, for sure. Lambda authorizers can integrate with external identity providers, including OAuth2, OpenID Connect, and others, to validate tokens or credentials.
