AWS Certified Developer Associate DVA-C02 Practice Question

The best practice for managing secrets is to use a dedicated secret management service, which allows for secure storage, fine-grained access control, auditing, and rotation of secrets without embedding them in the application's code or environment. AWS offers AWS Secrets Manager and AWS Systems Manager Parameter Store for this purpose, allowing you to store data securely as encrypted parameters and strictly manage access via IAM policies. Embedding credentials directly in the code is insecure and makes rotation difficult. Using an object storage service can partially solve the problem but lacks the dedicated secret management functionalities like automated rotation. Using custom attributes in a user management service is not the service's intended use and does not provide the rigorous management or auditing capabilities required for handling application secrets securely.
