Configuring Roles

Role management in DataArts Security provides more intuitive and powerful permission management capabilities based on permission sets. The difference between a role and a permission set is that a permission set directly associates users with permissions, while a role is created or managed on the data source to carry the association between users and permissions.

If you associate roles with permission sets on the role management page, permissions are synchronized only to roles instead of users. You are advised to use role management to manage permissions and permission relationships more intuitively. Role management also allows you to use managed roles to manage existing data source permissions.

Common roles: Create roles on the data source to associate users and permissions.
Manage roles: Manage existing roles on the MRS data source and inherit their permissions of the MRS data source. (To view existing roles on the MRS data source, log in to MRS FusionInsight Manager and choose System > Permission > Role).

This section describes Configuring a Common Role, Configuring Managed Roles, and Related Operations.

Prerequisites

You have configured a workspace permission set. For details, see Configuring Workspace Permission Sets.
During the synchronization of MRS and GaussDB(DWS) roles, the system uses the users in the data connections in Management Center to perform addition, deletion, modification, and query operations. Users in the data connections must have the following permissions:
- Users in MRS Ranger connections must have the admin permission of the Ranger component.
- In non-rights separation mode (RSM), database users in GaussDB(DWS) connections must have at least the dbadmin permission of the database. In RSM, users must have the system administrator permissions.
For details about the configuration method, see Checking the Cluster Version and Permissions.
Metadata of tables has been collected in DataArts Catalog through a metadata collection task if you want to view the metadata of databases, tables, and fields in data connections during permission configuration in fast mode.

Constraints

Currently, roles can only be created for MRS and GaussDB(DWS) clusters.
Workspace permission sets are mainly used to define the permissions of workspaces rather than manage permissions. Roles cannot be created for workspace permission sets.
During authorization, the name of the object to be authorized (database, table, or column name) can contain only digits, letters, underscores (_), hyphens (-), and wildcards (*).
If you create roles for permission sets, permissions are synchronized only to roles instead of users.
Role management is available only when the version of the CDM cluster selected for the agent in the data connection is 2.10.0.300 or later.
During the synchronization of MRS and GaussDB(DWS) roles, the system uses the users in the data connections in Management Center to perform addition, deletion, modification, and query operations. Users in the data connections must have the following permissions:
- Users in MRS Ranger connections must have the admin permission of the Ranger component.
- In non-rights separation mode (RSM), database users in GaussDB(DWS) connections must have at least the dbadmin permission of the database. In RSM, users must have the system administrator permissions.
For details about the configuration method, see Checking the Cluster Version and Permissions.
Only the directory permissions of the cluster are displayed for roles in the workspace.
During permission synchronization, you need to configure required permissions for the dlg_agency. For details, see Authorizing dlg_agency.
The current data permission control uses the allowlist mechanism, which adds operation conditions to the users to be authorized without affecting the permissions the users already have. If you only want to make the permissions granted by the data permission control take effect, you need to revoke the original permissions of the users to be authorized. For details, see Data Permission Management.
During script execution and job testing in DataArts Factory, the MRS or GaussDB(DWS) data source uses the account of the data connection for authentication by default. Therefore, permission management still does not take effect during data development. You need to enable fine-grained authentication so that the current user is used for authentication during script execution and job testing in DataArts Factory. In this way, different users have different data permissions, and permission management for roles and permission sets takes effect.

Configuring a Common Role

On the DataArts Studio console, locate a workspace and click DataArts Security.
In the navigation pane on the left, choose Role Management.

Use either of the following methods to configure a common role:

Configuring an existing role: On the Role Management page, permission sets that have been created in Creating a Permission Set are displayed in the navigation tree as common roles by default. You can click a role name to go to the role details page.
Figure 1 Role details page

Creating a role: On the Role Management page, click

in the navigation tree and select Create Common Role. Set the parameters listed in Table 1 and click OK. The details page of the created role is displayed by default.

**Table 1** Parameters
Parameter	Description
*Name	Permission set name, which is unique in the instance. You should include the meaning of the permission set and avoid meaningless descriptions in the name so that the permission set can be quickly identified.
*Parent Permission Set	Select a parent permission set, which can be a workspace permission set or another permission set. After you select a parent permission set, the permissions of the current permission set are a subset of the parent permission set's permissions.
*Administrator	The administrators are the owners of the permission set and can configure the permissions in the permission set. The administrators can perform the following operations: Permission configuration: Assign data source permissions to the workspace permission set. User configuration: Assign permissions in the workspace permission set to users, user groups, or workspace roles. Permission set creation: Create permission sets and roles based on the workspace permission set. The created permission sets do not contain more permissions than the workspace permission set.
Description	Information to make the permission set easier to be identified

Figure 2 Creating a common role

On the role details page, you can expand the Basic Information area to view the name, ID, and administrator of the role. For details, see Figure 3.

After configuring roles and permissions, you can synchronize them by clicking Synchronize Permissions and Synchronize Role Information in the upper right corner.
Figure 3 Basic role information
Data Source Role Configuration: On this page, you can click Create to create roles for associating users and permissions.

Figure 4 Data Source Role Configuration page

Click Create. In the displayed dialog box, select data sources, set Role Name, and click OK.

Figure 5 Creating a data source role

If you no longer need a data source role, click Delete in the Operation column to delete the role. After the role is deleted, permissions are no longer synchronized to the role and only synchronized to user information.
Permissions: On the role details page, click the Permissions tab. By default, By data is selected. You can also select By permissions. The configured permissions are the same for By data and By permissions, and the only difference lies in how the permissions are displayed. You are advised to select By permissions for batch authorization.
- By data: The system allows you to configure permissions for data. Currently, only MRS data sources are supported.
  Figure 6 Configuring permissions on the By data page
  
  When configuring permissions, you can select Entire DB, Entire table, or Entire column, and select the corresponding levels in the data source information to perform a batch authorization. You can also click Authorization in the Operation column of a data record in the expanded navigation pane to authorize access to the data.
  Fast mode and Show data this role has no permission to are supported. If Fast mode is enabled, metadata of databases, tables, and columns is obtained from DataArts Catalog. Otherwise, metadata is obtained from the data source. If metadata has been collected, you are advised to enable Fast mode.
  Note that the permissions of databases, tables, and columns are managed by layer. For example, a user who has been granted database permissions does not have the permissions of tables and columns. Table and column permissions must be granted separately.
  For example, if you enter a table name or an asterisk (*) as a wildcard during database authorization, you are authorizing the table. If you enter a column name or an asterisk (*) as a wildcard character, you are authorizing the column.
  
  During authorization, the name of the object to be authorized (database, table, or column name) can contain only digits, letters, underscores (_), hyphens (-), and wildcards (*).
  Figure 7 Authorization on the By data page
- By permissions: The system allows you to configure permissions.
  To configure permissions, click Add and select data levels in sequence. You cannot select multiple objects at the same level (such as database, table, and column) for batch authorization. Permission Type cannot be set to DENY.
  Note that the permissions of databases, tables, and columns are managed by layer. For example, a user who has been granted database permissions does not have the permissions of tables and columns. Table and column permissions must be granted separately.
  For example, if you enter a table name or an asterisk (*) as a wildcard during database authorization, you are authorizing the table. If you enter a column name or an asterisk (*) as a wildcard character, you are authorizing the column.
  
  During authorization, the name of the object to be authorized (database, table, or column name) can contain only digits, letters, underscores (_), hyphens (-), and wildcards (*).
  
  When you select HIVE for Data Source Type, you can change Database to URL to authorize an OBS path in the storage-compute decoupling scenario. In this scenario, the following URL permissions are required for using Hive:
  
  write: creating a database
  
  read: creating a table, writing data, and deleting a table
  After configuring permissions, you can edit, synchronize, or delete them.

After the role is configured, it does not take effect immediately. You need to synchronize the permissions and role to the data source for permission management to take effect. For details, see Related Operations.

Configuring Managed Roles

On the DataArts Studio console, locate a workspace and click DataArts Security.
In the navigation pane on the left, choose Role Management.
On the Role Management page, click in the navigation tree and select Create Managed Role. In the displayed dialog box, select a Ranger connection, set Parent Permission Set/Role, and click Manage in the Operation column of the MRS roles to be managed. You can also select multiple MRS roles to be managed and click Manage above the list.

If you no longer want to manage roles, you can delete the managed roles from the role management navigation tree. After the managed roles are deleted, permissions are no longer synchronized to the roles and only synchronized to user information.

Figure 13 Creating a managed role
Close the Manage Role dialog box and return to the Role Management page. In the role management navigation tree, locate the MRS role added in the previous step and click the role name to go to the role details page.
On the role details page, you can expand the Basic Information area to view the name, ID, and administrator of the role. For details, see Figure 14.

After configuring roles and permissions, you can synchronize them by clicking Synchronize Permissions and Synchronize Role Information in the upper right corner.

The permissions configured for the managed role do not take effect immediately. You need to manually synchronize the permissions to the Ranger component for permission management to take effect. For details, see Synchronizing Permissions.

Related Operations

Synchronizing permissions: After configuring data permissions on the Role Management page, you need to synchronize the permissions to the data source for permission management to take effect.
To synchronize permissions, click Synchronize Permissions in the upper right corner of the Basic Information area on the role details page. To synchronize the permissions of multiple roles, select the roles in the role management navigation tree and click above the navigation tree.
Synchronizing roles: In common role management (managed roles do not need to be synchronized), after a role is created for a permission set, the role takes effect only after being synchronized to the data source.
To synchronize a role, click Synchronize Role Information in the upper right corner of the Basic Information area or click Synchronize in the Operation column on the Data Source Role Configuration tab page. To synchronize multiple roles, select the roles in the role management navigation tree and click above the navigation tree.
- After role synchronization is successful, MRS data source roles are named in Role name_Timestamp format, and the GaussDB(DWS) data source roles are named in dataarts_studio_role_Role name format.
- In scenarios where roles are synchronized to an MRS cluster, after the system prompts a successful role synchronization, permission management takes effect after about five minutes during which the Ranger component automatically synchronizes roles from the MRS cluster. You can check whether the synchronization is complete based on Data Source Role Name on the Data Source Role Configuration tab page.
  - Roles that are not synchronized are named in Role name_10-digit timestamp format.
  - Roles that have been synchronized are named in Role name_13-digit timestamp format.
Deleting roles: In the Role Management navigation pane, select roles and click above the navigation pane. In the displayed dialog box, confirm the roles to be deleted and click Yes.
Common roles for which roles, permissions, users, or child permission sets have been configured cannot be deleted. To delete such roles, delete the related configurations first. If permissions have been configured for a managed role, the role cannot be deleted. To delete the role, clear related configurations first.

Deleted common roles are moved to the recycle bin. You can restore them within 30 days. After 30 days, they will be deleted permanently. For details, see Managing the Recycle Bin.
