Only a bucket owner can, when creating a bucket, set bucket read and write permissions using Access Control List (ACL). The owner can also modify the ACL for that bucket according to service requirements. Currently, three access permissions are available for a bucket:
| Permission | Access Restriction |
|---|---|
| public-read-write | Anyone, including anonymous users, can perform read and write operations on the files in the bucket. The fees incurred by these operations will be borne by the owner of the bucket. Use this permission with caution. |
| public-read | Only the owner of the bucket can perform write operations on the files in the bucket, while others (including anonymous users) can perform read operations on the files. |
| private | Only authorized users are allowed to read, write, and delete files in the bucket. Others cannot access the files in the bucket without authorization. |
For details, refer to Access Permissions.
