In order to enforce the principle of least privilege and assist with data privacy efforts, EmpowerID provides fine-grained control to limit which user interfaces, APIs, and workflows a user may see/use and also control over which data they may see.
User Interface Visibility Restrictions (aka “Security Trimming”)
Controls which pages and controls on pages a user may see
Can refer to controlling which data objects (i.e. groups, people, roles) a person may see
Control of access to view pages and controls is based on RBAC delegations to a person or their roles, groups, etc.
Control of visibility of data is based on Visibility Restriction policies which are also assigned to people by role and location, group, query-based collection, etc.
The Noun, Verb, Action navigation system also leverages security trimming to filter which options are displayed
How is Security Trimming implemented?
In the Noun, Verb, Action navigation system, each UI Action links to a specific page or workflow. The system will only return actions for which the person has the “use” (aka view) operation.
The left navbar has a special wrapper for each node to only show it if has access
In specific pages security trimming can be implemented by:
Check access to page or control - if (EidAuthenticationHandler.HasAccessToPage(new Guid("22231fdf-cc2a-4e00-8a40-655be8af3fc1")))
Check access for an operation to current object like a person –
if(Model.HasAccessToOperation("ViewAdvancedPersonAttributes"))
if (EidContext.HasAccessToOperation((int)Model.GetProperty("ResourceID"), "Edit Person Demographics"))
Data Visibility Restrictions
EmpowerID provides the ability to control who may see which objects and which object attributes at the lowest level in the Identity Warehouse database. Three types of policies are available to limit and control this access:
Visibility Restriction policies are policies that you can create to limit the ability of people to view (objects) in EmpowerID in the user interface and via the API. These policies are similar to RBAC delegations in that you can assign them to any EmpowerID Actor, such as a Management Role, Group, Query-Based Collection (SetGroup), and so forth.
Data Visibility Filters are SQL-based filters written against the EmpowerID Identity Warehouse, they offer great flexibility and power, allowing you to show and hide objects based on any data in the Identity Warehouse.
Column Visibility Filters are SQL-based filters written against the EmpowerID Identity Warehouse, they offer great flexibility and power, allowing you to show and hide data in the Identity Warehouse at the column and attribute level.
