EnableSnapshotBlockPublicAccess

Enables or modifies the block public access for snapshots setting at the account level for the specified AWS Region. After you enable block public access for snapshots in a Region, users can no longer request public sharing for snapshots in that Region. Snapshots that are already publicly shared are either treated as private or they remain publicly shared, depending on the State that you specify.

Important

Enabling block public access for snapshots in block all sharing mode does not change the permissions for snapshots that are already publicly shared. Instead, it prevents these snapshots from be publicly visible and publicly accessible. Therefore, the attributes for these snapshots still indicate that they are publicly shared, even though they are not publicly available.

If you later disable block public access or change the mode to block new sharing, these snapshots will become publicly available again.

For more information, see Block public access for snapshots in the Amazon EBS User Guide.
