The Trusted Advisor S3 Bucket Permissions Monitor demonstrates how to use AWS Lambda to perform IT SecOps automation in response to an Amazon CloudWatch Event generated by AWS Trusted Advisor.
On detection of a Trusted Advisor S3 Bucket Permissions CloudWatch Event this automation removes the public permissions to list and write objects to the exposed bucket, as well as the permissions to read and write to the bucket's ACLs. Once the public permissions have been removed a notification message is sent to an Amazon Simple Notification Service (SNS) topic to notify the subscribers.
