AWS CloudTrail

The cloudtrail log type monitors events from the AWS CloudTrail accounts. OpenSearch can ingest AWS CloudTrail log data from both Amazon Simple Storage Service (Amazon S3) accounts and Amazon Security Lake accounts.

The following code snippet contains all the raw_field, ecs, and ocsf mappings for this log type:
