Which AWS service will help identify who made the change?

Explanations:

AWS Config provides a detailed history of configuration changes made to AWS resources. It tracks changes to configurations and allows you to view resource relationships, making it possible to identify who made the change to the Auto Scaling group settings.

Amazon Inspector is a security assessment service that helps improve the security and compliance of applications deployed on AWS. It does not provide audit logs or history of configuration changes for AWS resources.

Amazon Macie is a security service that uses machine learning to discover, classify, and protect sensitive data in AWS. It is focused on data security rather than tracking configuration changes of resources like Auto Scaling groups.

Amazon CloudWatch Logs is used for monitoring and logging application and infrastructure performance, but it does not directly track changes to resource configurations or who made those changes. It is more focused on performance and operational metrics.
