# How to Activate CloudTrail in Your AWS Environment

### Introduction

AWS CloudTrail is a service that enables governance, compliance, and operational and risk auditing of your AWS account. It logs all API calls made within your AWS environment, including those made through the AWS Management Console, AWS SDKs, command-line tools, and other AWS services.

### Why is CloudTrail Important?

With CloudTrail, you can keep an eye on and archive account activity linked to actions taken throughout your AWS infrastructure. It may be essential for compliance obligations, security audits, and identifying any strange activity in your account.

### Setting Up CloudTrail in a Single Account

2. S3 bucket (optional, but necessary if storing logs outside of the default location).
