Amazon CloudTrail S3 Data Events allow you to record API actions on Amazon S3 objects and receive detailed information such as the Amazon Web Services account, IAM user role, and IP address of the caller, time of the API call, and other details. You can programmatically access and act upon the Data Events after they are delivered to an Amazon S3 bucket or to Amazon CloudWatch Events. For example, you can quickly reapply the original Access Control List (ACL) on an object if the ACL of an object is modified.
