Role-Based Access Control (RBAC)

This article shows how to create a user for a practitioner and allow practitioners to read patients data.
Aidbox provides role-based access control mechanism based on access policies and Role resource.
Each Role resource assigns a role to a User. AccessPolicy resource has an optional roleName property. Aidbox applies access policy with roleName specified only to users which have the corresponding role assigned.

Guide: flexible RBAC

Create a patient

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

Create a user

Create a user containing practitioner role.
POST /User
id: user-1
resourceType: User
- 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
- value: practitioner
uri: '#/Patient/.*'
request-method: get
Please note that if you like to add multiple request methods when using matcho engine you should use $one-of notation:
- get
- post
- put

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.
