Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 418 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional SAP-C02
Question #: 418
Topic #: 1
[All AWS Certified Solutions Architect - Professional SAP-C02 Questions]

A company needs to improve the security of its web-based application on AWS. The application uses Amazon CloudFront with two custom origins. The first custom origin routes requests to an Amazon API Gateway HTTP API. The second custom origin routes traffic to an Application Load Balancer (ALB). The application integrates with an OpenID Connect (OIDC) identity provider (IdP) for user management.

A security audit shows that a JSON Web Token (JWT) authorizer provides access to the API. The security audit also shows that the ALB accepts requests from unauthenticated users.

A solutions architect must design a solution to ensure that all backend services respond to only authenticated users.

Which solution will meet this requirement?

  • A. Configure the ALB to enforce authentication and authorization by integrating the ALB with the IdP. Allow only authenticated users to access the backend services.
  • B. Modify the CloudFront configuration to use signed URLs. Implement a permissive signing policy that allows any request to access the backend services.
  • C. Create an AWS WAF web ACL that filters out unauthenticated requests at the ALB level. Allow only authenticated traffic to reach the backend services.
  • D. Enable AWS CloudTrail to log all requests that come to the ALB. Create an AWS Lambda function to analyze the logs and block any requests that come from unauthenticated users.

Option A is right, this solution meets the requirement of ensuring that all backend services respond to only authenticated users: 1) Authentication at the load balancer level: By configuring the ALB to integrate with the OIDC IdP, you can enforce authentication and authorization for incoming requests. 2) Preventing unauthenticated requests: The ALB will reject any requests from unauthenticated users, ensuring that only authenticated users can access the backend services.
