AWS Certified DevOps Engineer – Professional (DOP-C02) — Question 166

A company uses an organization in AWS Organizations to manage several AWS accounts that the company's developers use. The company requires all data to be encrypted in transit.

Multiple Amazon S3 buckets that were created in developer accounts allow unencrypted connections. A DevOps engineer must enforce encryption of data in transit for all existing S3 buckets that are created in accounts in the organization.

Which solution will meet these requirements?

Answer options

• A. Use AWS CloudFormation StackSets to deploy an AWS Network Firewall firewall to each account. Route all outbound requests from the AWS environment through the firewall. Deploy a policy to block access to all outbound requests on port 80.
• B. Use AWS CloudFormation StackSets to deploy an AWS Network Firewall firewall to each account. Route all inbound requests to the AWS environment through the firewall. Deploy a policy to block access to all inbound requests on port 80.
• C. Turn on AWS Config for the organization. Deploy a conformance pack that uses the s3-bucket-ssl-requests-only managed rule and an AWS Systems Manager Automation runbook. Use a runbook that adds a bucket policy statement to deny access to an S3 bucket when the value of the aws:SecureTransport condition key is false.
• D. Turn on AWS Config for the organization. Deploy a conformance pack that uses the s3-bucket-ssl-requests-only managed rule and an AWS Systems Manager Automation runbook. Use a runbook that adds a bucket policy statement to deny access to an S3 bucket when the value of the s3:x-amz-server-side-encryption-aws-kms-key-id condition key is null.

Correct answer: C

Explanation

Option C is correct because it uses AWS Config with a managed rule to ensure that S3 buckets only accept SSL requests, thus enforcing encryption in transit. Options A and B focus on using AWS Network Firewall but do not specifically address S3 bucket configurations for SSL requirements. Option D incorrectly targets a different condition key that does not relate to enforcing SSL for data in transit.
