I am trying to understand what are really the changes done on Keystone and Horizon forks by GING and are these needed only for the Fiware Lab (i.e. are the Fiware Lab specific)?
We are making our proper Fiware installation for Mainflux IoT Cloud: https://github.com/Mainflux/mainflux, and we are using Orion and IoT Agents. We want to add security layer with Wilma and IDM, and we are wondering if we need Keyrock modifications, or we can use vanilla Keystone and Horizon from OpenStack directly.
Will Wilma work with unchanged Keystone and Horizon from OpenStack?
BR,

we've introduce several extensions such us OAuth2, SCIM, user-registration, two factor authentication... We have also modified the UX to fit FIWARE Lab look&feel. And also some administration tools for region management, emails, etc. Wilma will work with vanilla Keystone if you configure it to use keystone tokens. But not with oauth2 tokens.

First of all, I'm using the Telefonica implementations of Identity Manager, Authorization PDP and PEP Proxy, instead of the Fiware reference implementations which are Keyrock, AuthZForce and Wilma PEP Proxy. The source code and reference documentation of each component can be found in the following GitHub repos:
Telefonica keystone-spassword:
GitHub /telefonicaid/fiware-keystone-spassword
Telefonica keypass:
GitHub /telefonicaid/fiware-keypass
Telefonica PEP-Proxy:
GitHub /telefonicaid/fiware-pep-steelskin
Besides, I'm working with my own in-house installation of the components, NO Fi-Lab. In addition to security components, I've an IoT Agent-UL instance and an Orion Context Broker instance.
Starting from that configuration, I've created a domain in keystone (Fiware-Service) and a project inside the domain (Fiware-ServicePath). Then I've one device connected to the platform, sendding data to the IoT Agent behind the PEP Proxy. The whole device message is represented as a single Entity in Orion Context Broker.
So, the question is:
How can I restrict a specific keystone user to access only to the entity associated to this device, at the level of the Orion Context Broker API?
I know that I can allow/deny user acces to specific API via keystone Roles and XACML Policies but that implies that I should create one Policy per User-Device pair.
I could use some help with this, to know if I'm on the right way.
I do not think Access Control can be done to Orion without Security GEs. Each GE has a specific purpose and access control is not one of the Orion's purposes.
As stated in the Security Considerations from Orion documentation:
Orion doesn't provide "native" authentication nor any authorization mechanisms to enforce access control. However, authentication/authorization can be achieved the access control framework provided by FIWARE GEs.
Also, there is something related in another link:
Orion itself has no security. It’s designed to be run behind a proxy server which provides security and access control. Used within the FIWARE Lab, they run another service build on node.js, “PEP Proxy Wilma”, in front of it. Wilma checks that you have obtained a token from the FIWARE lab and put it in the headers.
Besides, the link below can endorse my opinion about Orion and access control:
Fiware-Orion: Access control on a per subscription basis
My opinion is that you are in the right way using the other security components.
About "create one Policy per User-Device pair" as you mention, maybe it would be better you thought about "group policies" instead.
Can the Fiware enabler AuthZforce be used without keyrock and wilma?
can it be used using others pep and IDM?
Yes, it can. The AuthZForce API is not designed specifically for KeyRock/Wilma. Just to clarify, KeyRock consumes the PAP API of AuthZForce, and Wilma consumes the PDP API of AuthZForce. To achieve that, the KeyRock/Wilma team have developed their own AuthZForce API connectors, i.e. the client part that consumes AuthZForce API. So if you use another PEP/IdM, you have to develop a similar connector for this particular PEP/IdM, if it is not already there. A the end of the user guide, we give some hint to help develop your own Authzforce API client. In any case, all you need is a good HTTP/REST/XML framework to start with.

We want to use the FIWARE IdM, both Keystone and Horizon. Specifically during sign-up we want to
create a user
add that user to an organisation
authorise the user for an application
We have installed Keystone and Horizon using the latest KeyRock docker image on the docker hub.
When a new user signs up:
a 'cloud organisation' is created.
By default, the 'provider' and 'purchaser' roles are present
and the 'Store' application is assigned to the user (although i cannot verify this).
We can add the user to an organisation by hand, and authorise the user for an application by hand in the KeyRock UI.
However this does not make any sense for our local installation.
How can we prevent Horizon from creating the cloud organisation upon user sign-up?
How can we assign a default application authorization upon user sign-up?
-- Edit --
It’s becoming increasingly clear to me that the way KeyRock is implemented is primarily useful for setting up your own Fiware labs environment, as opposed to setting up a generic Identity management service. If we use KeyRock, we will be stuck with cloud organisations, stores etc. Far from being a Generic Enabler (GE), KeyRock seems to be a “Fiware Labs” specific enabler.
All the GE documentation references KeyRock as the reference Identity Management GE. Therefore we (and i assume others too) have followed the documented architecture and configuration to link to KeyRock from:
Wilma PEP Proxy GE
Wirecloud Application Mashup GE
Because of the inbuilt Fiware Labs functions of KeyRock, we are having a really hard time applying Wilma PEP Proxy and Wirecloud Application Mashup to our use cases.
If we decide to use Keystone instead, we will lose
OAuth2 support
Permissions
sign-up, admin and login screens.
Is anyone else having this problem?
How have they tackled it?
-- SCIM API --
Attempt at using the SCIM API is described here: Fiware KeyRock SCIM API bug: _check_allowed_to_get_and_assign() got an unexpected keyword argument 'userName'
I'm deploying some Generic Enablers(Orion, Cygnus, Proton-Cep, Wirecloud) in the same VM using dockers.
Reading the fiware documentation it uses has an example a wilma proxy securing an instance of orion and getting the authorization through IdM.
Wilma configurations do not seem to support different redirections
I need to secure all these services that I'm using which need to be accessed from outside the server, my question is if is it possible to use Wilma to secure all Generic Enablers or should I implement one instance of Wilma for each service provided?
We're developing a smart cities service and want to use KeyRock for our users authentication. We don't want to use existing FIWARE Lab instance though, but create our own. The FIWARE catalogue states:
It can be integrated with any development, specially with any Cloud service.
I would expect that KeyRock would be a generic component, that would allow us to add Single Sign-On authentication to our services. After KeyRock installation, however, I can see it's highly tied to FIWARE Lab:
there is a FIWARE Lab menu at the top,
I can see FIWARE-related content on logging in page,
as an admin I can set users' FIWARE Lab account type (trial, community).
Is my assumption, that KeyRock can be used outside of FIWARE Lab context correct? Is there a way to brand it to my own purposes and turn off the FIWARE Lab-related functionalities? Or should it only be used as a part of FIWARE Lab instance?
yes, the front end component (Horizon) is fixed to FIWARE look and field and FIWARE Lab user account policies. If you want to use it with your own GUI design you have to modify it yourself.
On the other hand the backend component (Keystone) can be used without changes as an "universal" idm.
