AWS CloudTrail Not Enabled In All Regions

What It Does

This policy template reports if there is not at least one CloudTrail trail that is fully multiregion. Optionally, this report can be emailed.

AWS CloudTrail is a web service that records AWS API calls for your account and delivers log files to you. It is considered good practice to enable CloudTrail across all regions.

How It Works

The policy leverages the AWS CloudTrail API to obtain a list of trails. Each trail is checked to see if IsMultiRegionTrail is set to "true", IsLogging set to "true", and if the trail has at least one Event Selector with IncludeManagementEvents set to "true" and ReadWriteType set to "All". If no trails are found that meet these criteria, an incident is raised.
