# Cloud Activity Tracer permissions management

Available in Classic and VPC

 

You can set access permissions for Cloud Activity Tracer using Sub Account, NAVER Cloud Platform's account management service. Sub Account offers both system-managed (System Managed) and user-defined (User Created) policies to help you configure management and operation permissions.

              Note

              

Sub Account is a free service with no additional charges. For more information about Sub Account, see [**Services > Management & Governance > Sub Account**](https://www.ncloud.com/product/management/subAccount) on the NAVER Cloud Platform portal and the [Sub Account user guide](/docs/en/subaccount-overview).

## System-managed policies

System-managed policies are pre-built, role-based policies that NAVER Cloud Platform provides for your convenience. A sub-account created through the Sub Account service can be granted access to Cloud Activity Tracer by assigning a system-managed policy. Listed below are brief descriptions of the system-managed policies for Cloud Activity Tracer.

| Policy Name | Description |
| --- | --- |
| NCP_ADMINISTRATOR | Full access to all services, same as the main account |
| NCP_INFRA_MANAGER | Access to all services, except **My Account** > **Billing and Cost Management** > **Billing and Payments** in the console |
| NCP_FINANCE_MANAGER | Access only to Cost Explorer and **My Account** > **Billing and Cost Management** > **Billing and Payments** in the console |
| NCP_CLOUD_ACTIVITY_TRACER_MANAGER | Full access to all features of the Cloud Activity Tracer service |
| NCP_CLOUD_ACTIVITY_TRACER_VIEWER | Read-only access to the Cloud Activity Tracer service |

## 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 Cloud Activity Tracer:

| Type | Action | Related action | Resource type | Group by resource type | Action description | Condition Key |
| --- | --- | --- | --- | --- | --- | --- |
| View | View/getActivityList | - | - | - | View activity history | - All principal properties condition keys |
| View | View/getBucketList | - | - | - | View the list of activity export Buckets | - All principal properties condition keys |
| View | View/getTracerDetail | View/getTracerList | Tracer | Tracer | View Tracer details | - All principal properties condition keys - ncp:resourceTag |
| View | View/getTracerList | - | - | - | View tracer list | - All principal properties condition keys |

| Change | Change/writeObject | View/getBucketList | ObjectStorage:Bucket | Tracer | Select a Bucket to export activity history | - All principal properties condition keys - ncp:resourceTag |
| Change | Change/tagTracer | View/getTracerList View/getTracerDetail | Tracer | Tracer | Tag a tracer | - All principal properties condition keys - ncp:resourceTag - ncp:requestTag |
| Change | Change/untagTracer | View/getTracerList View/getTracerDetail | Tracer | Tracer | Delete a tag on a tracer | - All principal properties condition keys - ncp:resourceTag - ncp:requestTag |

              Caution

              

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.
