You can set different access permissions for Ncloud Storage using NAVER Cloud Platform's Sub Account service. Sub Account offers both system-managed (System Managed) and user-defined (User Created) policies to help you configure management and operation permissions.
Sub Account is a free service with no additional charges. For more information about Sub Account, see Services > Management & Governance > Sub Account on the NAVER Cloud Platform portal and the Sub Account user guide.
System-managed policies
System-managed policies are pre-built, role-based policies that NAVER Cloud Platform provides for your convenience. When you assign one of these policies to a sub account, that account gets access to Ncloud Storage. Here are the available system-managed policies for Ncloud Storage:
| Policy name | Policy description |
|---|---|
| NCP_ADMINISTRATOR | Full access to all services, same as the main account. |
| NCP_INFRA_MANAGER | Access to all services, except the My Account > Billing Information & Cost Management > Billing & Payment Management menu on the console. |

| NCP_NCLOUD_STORAGE_VIEWER | View-only access to all Ncloud Storage features. |
User-defined policies
User-defined policies let you create custom permissions. When you assign a user-defined policy to a sub account, that account can only perform the specific actions you've allowed. Here are the available user-defined policies for Ncloud Storage:

If you grant someone access to a specific action but not to the required related actions, they won't be able to complete their tasks. Sub Account automatically includes these related permissions to prevent this issue. However, if you manually uncheck these auto-selected related actions, the system assumes this was intentional and won't override your selection.
