AWS CloudTrail Insights for Data Events

AWS CloudTrail Insights now supports data events, enhancing your ability to detect and respond to unusual activity in your AWS accounts. This feature automatically detects anomalies in data access activities, such as unexpected surges in delete Amazon S3 object API calls or increased error rates for AWS Lambda function invocations.

CloudTrail Insights for data events works by establishing normal baselines for data access patterns and provides relevant data events when anomalies are detected. You can configure alerts for rapid response to potential threats or issues.
