Simple Role-Based Access Control

Aidbox provides role-based access control mechanism based on roles property in User resource.
This article demonstrates how to create a user for a practitioner and allow practitioners to read patients data.
See also Role-Based Access Control for a guide on flexible RBAC using Role resource.

Create a patient

POST /Patient
id: pt-1
resourceType: Patient
name:
- given:
- John

Create a user

Create a user containing practitioner role.
POST /User
id: user-1
resourceType: User
roles:
- value: practitioner

Create an access policy

Create an access policy which allows practitioners to read patients data.
POST /AccessPolicy
id: practitioner-role
resourceType: AccessPolicy
engine: matcho
matcho:
user:
roles:
- value: practitioner
uri: '#/Patient/.*'
request-method: get

Try it

Log in as user-1.
Read patient data
GET /Patient/pt-1
Aidbox will return you a Patient resource.

What's going on here

When you make a query
GET /Patient/pt-1
Aidbox router stores data in the request object:
  • Uri /Patient/pt-1 in the uri property.
  • Method get in the request-method property.
  • User data in user property. In particular user.roles[].value contains user roles.
Access policy engine evaluates request object. And here it checks that user.roles[].value property contains practitioner string.
You can inspect request object using __debug query parameter.
