What should a solutions architect do to accomplish this goal?
Turn on AWS Config with the appropriate rules.
Turn on AWS Trusted Advisor with the appropriate checks.
Turn on Amazon Inspector with the appropriate assessment template.
Turn on Amazon S3 server access logging. Configure Amazon EventBridge (Amazon Cloud Watch Events).
Explanations:
AWS Config allows you to assess, audit, and evaluate the configurations of your AWS resources, including S3 buckets. By turning on AWS Config with appropriate rules, you can monitor for unauthorized configuration changes effectively.
AWS Trusted Advisor provides best practices and checks on AWS accounts, but it does not specifically monitor S3 bucket configurations for unauthorized changes. It focuses more on resource optimization and cost management.
Amazon Inspector is primarily used for assessing the security and compliance of applications, particularly EC2 instances. It does not monitor S3 bucket configurations or track unauthorized changes.
While Amazon S3 server access logging and EventBridge can provide insights and notifications about access patterns, they do not directly monitor or enforce configuration compliance or changes for S3 buckets.
I rate that the answer is:
Turn on AWS Config with the appropriate rules.
