remediating-s3-bucket-misconfiguration
This skill provides step-by-step procedures for identifying and remediating Amazon S3 bucket misconfigurations that expose sensitive data to unauthorized access. It covers enabling S3 Block Public Access at account and bucket levels, auditing bucket policies and ACLs, enforcing encryption, configuring access logging, and deploying automated remediation using AWS Config and Lambda.

# 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.
