AWS Certified Solutions Architect – Professional — Question 230

During an audit, a security team discovered that a development team was putting IAM user secret access keys in their code and then committing it to an AWS
CodeCommit repository. The security team wants to automatically find and remediate instances of this security vulnerability.
Which solution will ensure that the credentials are appropriately secured automatically?

Answer options

• A. Run a script nightly using AWS Systems Manager Run Command to search for credentials on the development instances. If found, use AWS Secrets Manager to rotate the credentials.
• B. Use a scheduled AWS Lambda function to download and scan the application code from CodeCommit. If credentials are found, generate new credentials and store them in AWS KMS.
• C. Configure Amazon Macie to scan for credentials in CodeCommit repositories. If credentials are found, trigger an AWS Lambda function to disable the credentials and notify the user.
• D. Configure a CodeCommit trigger to invoke an AWS Lambda function to scan new code submissions for credentials. If credentials are found, disable them in AWS IAM and notify the user.

Correct answer: D

Explanation

The correct answer, D, ensures that any new code submissions are automatically scanned for credentials, and if found, those credentials are disabled immediately. This proactive approach prevents sensitive information from being stored in the repository. The other options either rely on manual processes or do not address the issue directly in a timely manner.
