AWS Certified Security – Specialty (SCS-C02) — Question 77

A company plans to create individual child accounts within an existing organization in AWS Organizations for each of its DevOps teams. AWS CloudTrail has been enabled and configured on all accounts to write audit logs to an Amazon S3 bucket in a centralized AWS account. A security engineer needs to ensure that DevOps team members are unable to modify or disable this configuration.

How can the security engineer meet these requirements?

Answer options

• A. Create an IAM policy that prohibits changes to the specific CloudTrail trail and apply the policy to the AWS account root user.
• B. Create an S3 bucket policy in the specified destination account for the CloudTrail trail that prohibits configuration changes from the AWS account root user in the source account.
• C. Create an SCP that prohibits changes to the specific CloudTrail trail and apply the SCP to the appropriate organizational unit or account in Organizations.
• D. Create an IAM policy that prohibits changes to the specific CloudTrail trail and apply the policy to a new IAM group. Have team members use individual IAM accounts that are members of the new IAM group.

Correct answer: C

Explanation

The correct answer is C because Service Control Policies (SCPs) can be used to manage permissions across accounts in AWS Organizations, ensuring that changes to the CloudTrail configuration are prohibited at the organizational level. Options A and D incorrectly apply IAM policies to specific users or groups, which do not provide the necessary control at the organizational level. Option B focuses on S3 bucket policies, which do not govern CloudTrail configuration changes.
