What is AWS CloudTrail?

CloudTrail is a service that enables governance, compliance, operational auditing, and risk auditing of your AWS account. It records API calls made on your account and delivers log files to your S3 bucket. CloudTrail provides visibility into user activity by tracking actions taken through AWS Management Console, SDKs, command line tools, and other AWS services. It helps with security analysis, resource change tracking, and compliance auditing by maintaining a comprehensive history of AWS API calls.
