Available in Classic and VPC
You can set different access permissions for Key Management Service 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.
As of November 23, 2023, the key permission management feature provided by Key Management Service is changed to be handled by detailed permission management through Sub Account. Existing role-based key permissions are migrated to the same level of policy. For more information, see Migration of role-based permissions.

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.
Migration of role-based permissions
The [Permission management] feature provided by Key Management Service is integrated into the Policy feature of Sub Account. The 5 roles of Key Manager, Key Encryptor, Key Decryptor, Key Encryptor and Decryptor, and Key Reviewer in operation are automatically migrated to policies with the same level of permissions. The migrated policies have the following permissions:
| Role name | Policy name to be migrated | Permissions to be migrated |
|---|---|---|
| Key Manager | KMS_KEY_MGR-{Key Id} | View*, Change* |
| Key Encryptor | KMS_KEY_ENC-{Key Id} | View/getKeyList, View/getKeyInfo, Change/encrypt, Change/reEncrypt, Change/createCustomKey, Change/sign |
| Key Decryptor | KMS_KEY_DEC-{Key Id} | View/getKeyList, View/getKeyInfo, Change/decrypt, Change/verify |
| Key Encryptor and Decryptor | KMS_KEY_ENC_DEC-{Key Id} | View/getKeyList, View/getKeyInfo, Change/encrypt, Change/reEncrypt, Change/createCustomKey, Change/sign, Change/decrypt, Change/verify |
| Key Reviewer | KMS_KEY_RVR-{Key Id} | View/getKeyList, View/getKeyInfo, View/getActivityList |
To view the migrated policies, navigate to 
> Services > Management & Governance > Sub Account > Policies and check the [User-defined policies] tab from the NAVER Cloud Platform console.
