What should a DevOps engineer do to meet these requirements?

Explanations:

While AWS CloudTrail can log S3 bucket actions, it does not enforce encryption, logging, or versioning for buckets. Automatic remediation using AWS Lambda would require additional setup and may not cover all bucket creation scenarios.

Enabling AWS Config rules allows monitoring of S3 bucket configurations. You can create custom rules to ensure encryption, logging, and versioning are enabled. Automatic remediation can be implemented using AWS Systems Manager documents to enforce compliance for both existing and future buckets.

AWS Trusted Advisor provides best practice checks but does not offer automatic remediation. Amazon CloudWatch Events can trigger actions but requires additional configuration, and it does not directly enforce the stated requirements for S3 buckets.

AWS Systems Manager provides management capabilities but does not inherently enforce security settings for S3 buckets. Automatic remediation using Systems Manager documents can help, but without the enforcement capabilities of AWS Config, it would not fully meet the requirement for existing and future buckets.
