Block public access for snapshots - Amazon EBS
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Block public access for snapshots

To prevent public sharing of your snapshots, you can enable block public access for snapshots. After you enable block public access for snapshots in a Region, any attempt to publicly share snapshots in that Region is automatically blocked. This can help you to improve the security of your snapshots and to protect your snapshot data from unauthorized or unintended access.

Block public access for snapshots can be enabled in one of two modes:

  • Block all sharing — Blocks all public sharing of your snapshots. Users in the account can't request new public sharing. Additionally, snapshots that were already publicly shared are treated as private and are no longer publicly available.

  • Block new sharing — Blocks only new public sharing of your snapshots. Users in the account can't request new public sharing. However, snapshots that were already publicly shared, remain publicly available.

Pricing

Block public access for snapshots can be enabled at no additional cost.
