This option allows the solutions architect to use an identity policy that grants the user readand write access to their own personal folder on the S3 bucket1. By adding a condition that specifies that the S3 paths must be prefixed with ${aws:username}, the solutions architect can ensure that each scientist can only access their own folder2. By applying the policy on the scientists’ IAM user group, the solutions architect can simplify the management of permissions for all the scientists3. By configuring a trail with AWS CloudTrail to capture all object-level events in the S3 bucket, the solutions architect can record and store information about every action performed on the S3 objects4. By storing the trail output in another S3 bucket, thesolutions architect can secure and archive the log files5. By using Amazon Athena to query the logs and generate reports, the solutions architect can use a serverless interactive query service that can analyze data in S3 using standard SQL.
