How to Investigate a Security Alert for a New Public Cloud Storage Bucket

A newly created public bucket may be an intentional website asset location or an accidental exposure of internal data. Storage permissions can be inherited or changed by policy after creation.

What to check

Confirm bucket owner, creation event, public access path, object inventory, data classification, access logs, and deployment purpose. Review whether public access is direct, signed, or controlled through a CDN.

Recommended next step

Restrict exposure promptly if the bucket is not approved, preserve audit evidence, and assess whether data was accessed. For legitimate public hosting, separate public assets from private data and document the configuration owner.
