The permissions settings for typical scenarios are provided to facilitate permissions management.

You need to consider the following factors before configuring permissions:

Who are granted access: A single IAM user, multiple IAM users or user groups, other accounts, or anonymous users
What resources will be accessed: All OBS resources (service-level permissions), specified buckets, or specified objects
What permissions are granted: Basic permissions, such as read and read/write permissions, or customized permissions

OBS provides various permission control methods for different scenarios. The following figure can help you quickly find the best method for your needs.
