How can AWS CloudTrail enhance cloud security?

AWS CloudTrail enhances cloud security primarily through its ability to log and monitor API calls made within an AWS environment. When an API call is made, CloudTrail captures the request details, such as the identity of the user or service making the request, the time of the request, the actions that were taken, and any associated resources. This logging capability provides a comprehensive audit trail, which is crucial for investigating security incidents, identifying unauthorized access attempts, and ensuring compliance with internal policies and regulatory requirements.

By maintaining detailed records of all actions taken in the AWS environment, CloudTrail enables organizations to establish security baselines, track changes, and monitor user activity effectively. This level of visibility helps detect anomalies, assess potential security threats, and respond to incidents promptly, thus reinforcing the overall security posture of the cloud infrastructure.
