Automated S3 Remediation with AWS Config & Systems Manager

Introduction Misconfigured Amazon S3 buckets are a leading cause of accidental data exposure in the cloud, resulting in regulatory fines, reputational damage, and costly data breaches. In this lab, we will look at a scenario that uses AWS Config and AWS Systems Manager Automation to automatically detect and remediate Amazon S3 buckets when Public Access Block settings are disabled. If Block Public Access is disabled on a bucket, either accidentally or unauthorized, AWS will automatically detect the non-compliant configuration and restore the secure settings. Prerequisites An AWS account with an IAM user that has AdministratorAccess.

Introduction

Misconfigured Amazon S3 buckets are a leading cause of accidental data exposure in the cloud, resulting in regulatory fines, reputational damage, and costly data breaches. In this lab, we will look at a scenario that uses AWS Config and AWS Systems Manager Automation to automatically detect and remediate Amazon S3 buckets when Public Access Block settings are disabled.

If Block Public Access is disabled on a bucket, either accidentally or unauthorized, AWS will automatically detect the non-compliant configuration and restore the secure settings.

Prerequisites
