This GitHub repository has been migrated. You can now find FHIR Works on AWS at https://github.com/aws-solutions/fhir-works-on-aws.

Purpose

Please visit fhir-works-on-aws-deployment for overall vision of the project and for more context.

This package is an implementation of the authorization interface from the FHIR Works interface. It uses role based access control (RBAC) to limit access to certain resource types and what operations one can do on those resource types. Cognito User Groups are used to determine which roles the user has. The User Group information is passed along in the OAuth access token when a user makes a request to the FHIR API. This means that the user must correctly obtained an access token from Cognito by using scopes of either:

• openid profile Must have both
• aws.cognito.signin.user.admin

To use and deploy this component (with the other 'out of the box' components) please follow the overall README

Infrastructure

This package assumes certain infrastructure:

• Cognito - is our idP
  • Users - created and managed inside of Cognito
  • User Groups - Used to determine which role the users have
  • OAuth - Used to provide an access token to the user. To understand the flow more see this link

Usage

For usage please add this package to your package.json file and install as a dependency. For usage examples please see the deployment component's package.json

Authorization rules

The rules are defined very simply and are in this format:

{
  <name-of-role>: {
    operations: [<array-of-operations-that-can-be-performed>],
    resources: [<array-of-resource-types>]
  }
}

For a working example please see RBACRules.ts in the deployment package
