PEP Proxy - Wilma

FIWARE Security Support badge

Wilma is a PEP Proxy - it can be combined with other security components such as Keyrock and Authzforce to enforce access control to your backend applications. This means that only permitted users will be able to access your Generic Enablers or REST services. Identity Management allows you to manage specific permissions and policies to resources allowing different access levels for your users.

This project is part of FIWARE. For more information check the FIWARE Catalogue entry for Security.

Docker

We also provide a Docker image and two version of the Dockerfile to facilitate you building this GE.

  • Here you will find the Dockerfile used in the automated build and the documentation explaining how to use it.
  • In Docker Hub you will find the public image.

A hacker's Dockerfile-sample file is also available in the root of the GitHub repository which can be used to build Docker images against a local codebase - It can be modified to suit your needs and allows you to create local images based on your own codebase if you want to make changes by yourself.

API

Requests to proxy should be made with a special HTTP Header: X-Auth-Token. This header contains the OAuth access token obtained from FIWARE IDM GE.

Example of requests:

GET / HTTP/1.1
Host: proxy_host
Authorization: Bearer z2zXk...ANOXvZrmvxvSg
GET / HTTP/1.1
Host: proxy_host
X-Auth-Token:z2zXk...ANOXvZrmvxvSg

To test the proxy you can generate this request running the following command:

curl --header "X-Auth-Token: z2zXk...ANOXvZrmvxvSg" http://proxy_host

or

curl --header "Authorization: Bearer z2zXk...ANOXvZrmvxvSg" http://proxy_host

Once authenticated, the forwarded request will include additional HTTP headers with user info:

X-Nick-Name: nickname of the user in IdM
X-Display-Name: display name of user in IdM
X-Roles: roles of the user in IdM
X-Organizations: organizations in IdM
