Delegated Admins¶
Delegated Admins in Apache Ranger and Privacera enable fine-grained delegation of administrative privileges. Instead of giving full administrative rights to every data steward or team lead, you can delegate policy management for specific resources to selected users or groups.
This helps enforce least privilege principles for administrative tasks while still allowing domain-specific teams to manage their own access control policies.
This capability is controlled at the policy level using the Delegate Admin
flag inside each policy item.
Use Cases¶
- A team lead who manages access to their own data lake tables
- A department head responsible for granting access to sensitive PII columns
- A BI admin who manages masking rules for dashboards in Snowflake or Databricks
- A data engineer who wants to share resources from their own personal workspace
How It Works¶
- Within a policy, the
Delegate Admin
option allows specified users/groups to manage that policy - They can view and edit only the policies where they are explicitly granted this privilege
- They cannot modify other policies, manage users, or configure system-wide settings unless granted separately
Example: Delegated Admin for Table¶
Allow SELECT
on sales_data.orders
to analysts
group, and delegate policy management to data_leads
group:
Field | Value |
---|---|
Groups (Access) | analysts |
Delegate Admin | data_leads |
Access Types | SELECT |
Resource | sales_data.orders |
Effect:
analysts
can query theorders
table- Members of
data_leads
can update this policy or add new rules under this scope
Scope of Delegated Admin
Since in the above example, the Delegate Admin
is given only to SELECT
privilege, the data_leads
group can only provide SELECT
access to other users or groups. This ensures that the delegated admin does not have full control over the resource.
Best Practices¶
- Use delegated admins to distribute policy management to appropriate domain owners
- Grant
Delegate Admin
only on policies that the user is meant to control - Combine with resource scoping (e.g., specific database or bucket) to avoid overreach
- Audit admin actions to ensure delegated privileges are used appropriately
UI Behavior¶
- Delegated Admins will only see and manage policies where they are explicitly marked as delegate
- In Privacera Portal, delegated admin users get a limited view of the Access Management tab
Difference from Security Zones¶
While Delegated Admins and Security Zones both aim to decentralize access control, they operate at different layers:
Feature | Delegated Admins | Security Zones |
---|---|---|
Scope | Per-policy level | Service-level, covering resource hierarchies |
Configuration | Defined inside individual policies | Defined in separate zone configuration |
Policy Visibility | Delegated admin can only manage allowed policies | Zone admin can only view and manage policies within their zone |
Purpose | Targeted delegation to manage specific access rules | Logical segmentation of services for distributed governance |
Enforcement | Access to policy edit rights | Access to create/manage policies within a zone |
They can also be used together. For example, within a security zone, a specific user can be designated as a delegated admin for certain policies.
