Build Status

Description:

This AWS CloudFormation solution deploys AWS CloudTrail, a service for governance, compliance, operational auditing, and risk auditing of your AWS account. This AWS CloudFormation template creates AWS KMS encryption keys for CloudTrail and S3, and enables CloudTrail for the account.

CloudTrail logs are encrypted (AES-256) and stored in an encrypted (AES-256) S3 bucket that the CloudFormation template creates. For security and compliance it is important all AWS account activity is tracked and stored for tracking and analysis.

CloudTrail

AWS CloudFormation provides a common language for you to describe and provision all the infrastructure resources in your cloud environment.

Using AWS CloudTrail, you can log, continuously monitor, and retain account activity related to actions across your AWS infrastructure. CloudTrail provides event history of your AWS account activity, including actions taken through the AWS Management Console, AWS SDKs, command line tools, and other AWS services. This event history simplifies security analysis, resource change tracking, and troubleshooting.
