What is AWS CloudTrail and how does it enhance security?

AWS CloudTrail is a service that enables governance, compliance, and operational and risk auditing of your AWS account. It enhances security by logging all API calls made in your account, allowing you to monitor and respond to changes.

Can you explain how CloudTrail logs can be used for security analysis?

Certainly! CloudTrail logs provide detailed records of API calls, including who made the call, when it was made, and what actions were taken. This information can be analyzed to detect unauthorized access or changes to resources.

What are some best practices for using CloudTrail to improve security?

Some best practices include enabling CloudTrail in all regions, integrating it with AWS CloudWatch for real-time monitoring, and ensuring logs are stored securely in S3 with proper access controls.

How long does CloudTrail retain logs by default?

By default, CloudTrail retains logs for 90 days. However, you can configure it to store logs in S3 for longer retention.
