Exam AWS Certified Security - Specialty SCS-C02 topic 1 question 203 discussion

Exam question from Amazon's AWS Certified Security - Specialty SCS-C02
Question #: 203
Topic #: 1
[All AWS Certified Security - Specialty SCS-C02 Questions]

A company is using an Amazon CloudFront distribution to deliver content from two origins. One origin is a dynamic application that is hosted on Amazon EC2 instances. The other origin is an Amazon S3 bucket for static assets.

A security analysis shows that HTTPS responses from the application do not comply with a security requirement to provide an X-Frame-Options HTTP header to prevent frame-related cross-site scripting attacks. A security engineer must make the full stack compliant by adding the missing HTTP header to the responses.

Which solution will meet these requirements?

  • A. Create a Lambda@Edge function. Include code to add the X-Frame-Options header to the response. Configure the function to run in response to the CloudFront origin response event.
  • B. Create a Lambda@Edge function. Include code to add the X-Frame-Options header to the response. Configure the function to run in response to the CloudFront viewer request event.
  • C. Update the CloudFront distribution by adding X-Frame-Options to custom headers in the origin settings.
  • D. Customize the EC2 hosted application to add the X-Frame-Options header to the responses that are returned to CloudFront.

It could be A or C - but what makes me thing A is the origin response and this scenario is covered here: https://aws.amazon.com/blogs/networking-and-content-delivery/adding-http-security-headers-using-lambdaedge-and-amazon-cloudfront/

Selected Answer: A
The best solution to meet the requirement of adding the X-Frame-Options HTTP header to the responses is: A. Create a Lambda@Edge function. Include code to add the X-Frame-Options header to the response. Configure the function to run in response to the CloudFront origin response event. This approach ensures that the header is added to all responses, regardless of the origin (EC2 or S3), and it does not require changes to the application code or the CloudFront distribution settings
