Securing your Amazon S3 buckets: Identifying and remediating over-permissioned access
Brief
Misconfigured Amazon Simple Storage Service (Amazon S3) buckets can expose your data to unauthorized access. Without proactive review, S3 bucket policies or Access Control Lists (ACLs) configured with broad access may go unnoticed in your environment.
In this post, you learn how to identify and fix over-permissioned S3 buckets across your AWS environment, along with best practice recommendations and automation opportunities to help you prevent security gaps. This post provides a workflow framework and methodology recommendations for your security team to adapt. The focus of this post is on the what and why rather than a prescriptive implementation.
You will need to customize the approach based on your organization’s requirements and existing security tooling.
