We're evaluating Apple-hosted Background Assets for an app distributed on App Store and would like to understand the security model behind it before adopting it.
So far the public documentation only mentions the HTTPS requirement for asset transport. We'd appreciate any additional documentation or guidance covering:
- How asset downloads are authenticated (e.g., is access tied to the app's entitlement/provisioning, or is there a separate token/credential mechanism?)
- How access to specific assets is controlled/scoped
- Where Apple-hosted assets are physically/logically hosted (e.g., is this CDN-backed, and is there any control or visibility over hosting region?)
- Any other security considerations typically associated with cloud-hosted content (encryption in transit and at rest, integrity verification, etc.)
Is there a more detailed security/architecture document beyond the public developer documentation, or can someone from the team point us in the right direction?
