<log_prefix>

Step-by-Step Guide for Remediation

2. 1.

   Open the AWS Management Console and navigate to the Amazon S3 service.

4. 2.

   Identify the S3 buckets that need to have their S3 data events logged in CloudTrail.

6. 3.

   Select one of the S3 buckets and click on its name to access the bucket details.

8. 4.

   In the bucket details page, go to the "Properties" tab.

10. 5.

    Under the "Management" section, click on "Edit" next to "Logging".

12. 6.

    Enable logging for the bucket by checking the "Enabled" box.

14. 7.

    Select or create a target S3 bucket where the CloudTrail logs will be stored. You can choose an existing bucket or create a new one.

16. 8.

    Specify the log file prefix that will be used to organize the CloudTrail logs. Optionally, you can choose to include the account ID or region in the prefix.

18. 9.

    Click on "Save" to enable the logging configuration for the bucket.

20. 10.

    Repeat steps 3-9 for each remaining S3 bucket that needs to have S3 data events logged in CloudTrail.

    Verify that the S3 bucket logging is successfully enabled by checking the CloudTrail service in the AWS Management Console.

24. 12.

    To double-check the logging configuration using the AWS CLI, use the following command:

aws s3api get-bucket-logging --bucket <bucket_name>

<bucket_name>

   Inspect the CloudTrail logs to ensure that S3 data events are being recorded accurately.
