AWS Config can continuously monitor and record your AWS resource configurations. It provides AWS Config rules that automatically check the configuration of AWS resources and notify you of compliance and non-compliance.
Steps:
Enable AWS Config:
Open the AWS Config console.
Follow the steps to set up AWS Config if it is not already enabled.
Add AWS Managed Rules:
In the AWS Config console, choose "Rules".
Add the s3-bucket-public-read-prohibited managed rule.
Configure the rule to check all S3 buckets.
Set Up SNS Notifications:
Create an Amazon SNS topic.
Subscribe your email or other communication channels to the SNS topic.
In AWS Config, configure the rule to send notifications to the SNS topic whenever there is a compliance change.
This approach ensures operational efficiency as AWS Config will automatically monitor S3 buckets and notify you through SNS if any bucket becomes publicly accessible.
