  title: Amazon S3 Provision a Secure Bucket
  summary: Create a bucket, enable versioning, and apply default encryption.
  description: >-
    A hardening flow that stands up a bucket ready for sensitive data. The
    workflow creates the bucket, enables versioning so object history is
    retained, and applies a default server-side encryption rule so new objects
    are encrypted at rest. The result is a bucket configured with two of the most
    common data-protection guardrails. Every step spells out its request inline so
    the flow can be read and executed without opening the underlying OpenAPI
    description.
