remediating-s3-bucket-misconfiguration
Provides step-by-step procedures for remediating Amazon S3 bucket misconfigurations that expose sensitive data: enabling S3 Block Public Access, auditing bucket policies and ACLs, enforcing encryption, configuring access logging, and deploying automated remediation with AWS Config and Lambda. Use when AWS Config or Security Hub flags public or unencrypted S3 buckets, or preparing audit evidence for storage security controls.

# Remediating S3 Bucket Misconfiguration
## When to Use
- When AWS Config or Security Hub reports S3 buckets with public access or missing encryption
- When a security scan reveals S3 bucket policies granting access to Principal "*" (everyone)
- When preparing for a data protection audit requiring evidence of storage security controls
- When responding to a data exposure incident involving publicly accessible S3 objects
- When establishing preventive controls for new S3 bucket creation across an AWS Organization
**Do not use** for Azure Blob Storage or GCP Cloud Storage misconfigurations, for S3 data classification (see implementing-cloud-dlp-policy), or for S3 access pattern analysis unrelated to security.
