S3 Access Logs
- For audit purpose, you may want to log all access to S3 buckets
- Any request made to S3, from any account, authorized or denied, will be logged into another S3 bucket
- That data can be analyzed using data analysis tools
- Or Amazon Athena as we'll see that later in the section.
- The log format is: https://docs.aws.amazon.com/AmazonS3/latest/dev/LogFormat.html
Warning
- Do not set your logging bucket to be the monitored bucket
- It will create a logging loop and your bucket will grow in size exponentially
