System-defined Permissions

By default, new IAM users do not have permissions assigned. You need to add a user to one or more groups, and attach permissions policies or roles to these groups. Users inherit permissions from the groups to which they are added and can perform specified operations on cloud services based on the permissions.

Scope: The projects for which permissions granted to a user group will be applied.

Global services: Services deployed without specifying physical regions, such as Object Storage Service (OBS) and Content Delivery Network (CDN), are called global services. Permissions for these services must be assigned globally.
Region-specific projects: Services deployed in specific regions, such as Elastic Cloud Server (ECS) and Bare Metal Server (BMS), are called project-level services. Permissions for these services must be assigned in region-specific projects and will be applied only for specific regions.
- All resources: Permissions will be applied for both global services and region-specific projects, including projects created later.
- Region-specific projects: Permissions will be applied for the region-specific projects you select.

Type: You can grant users permissions by using roles and policies. Policies are a type of fine-grained authorization mechanism that defines permissions required to perform operations on specific cloud resources under certain conditions. For details, see Permission.

For services that provide both policies and roles, preferentially use policies to assign permissions.
For services that support policy-based access control, you can create custom policies to supplement system-defined policies to allow or deny access to specific types of resources under certain conditions.
