Enabling log file integrity validation for CloudTrail
You can enable log file integrity validation by using the Amazon Web Services Management Console, Amazon Command Line Interface (Amazon CLI), or CloudTrail API. CloudTrail starts delivering digest files in about an hour.
Amazon Web Services Management Console
To enable log file integrity validation with the CloudTrail console, choose Yes for the Enable log file validation option when you create or update a trail. By default, this feature is enabled for new trails. For more information, see Creating and updating a trail with the console.
Amazon CLI
To enable log file integrity validation with the Amazon CLI, use the
--enable-log-file-validation option with the create-trail or update-trail commands. To
disable log file integrity validation, use the
--no-enable-log-file-validation option.
Example
The following update-trail command enables log file validation and starts
delivering digest files to the Amazon S3 bucket for the specified trail.
aws cloudtrail update-trail --name your-trail-name --enable-log-file-validation
CloudTrail API
To enable log file integrity validation with the CloudTrail API, set the
EnableLogFileValidation request parameter to true when calling
CreateTrail or UpdateTrail.
For more information, see CreateTrail and UpdateTrail in the Amazon CloudTrail API Reference.
