CX-0014 Employees and Technical Users v1.0.1

ABSTRACT

Identity and Access Management (IAM) is a mandatory basic infrastructure for every IT-System. The identity of any entity and actor (company, user, or technical client/connector) is the summary of the describing attributes (e.g., Company Name, Address, Tax Number, etc.). Catena-X is intended to be a network-of-networks which consequently means that there cannot be a single Identity Provider (IdP) for the company identities nested in one network. The company must be identifiable in an independent way and interoperable in all networks. The identity of users (employees of a company) and technical users (e.g., EDC) in Catena-X, must be bound to the company they are acting on behalf of.

1. Introduction

1.1 AUDIENCE & SCOPE

This section is non-normative

List for which roles the standard is relevant:

  • Core Service Provider
  • Data Provider / Consumer
  • Business Application Provider
  • Enablement Service Provider
  • Onboarding Service Provider
  • Consulting Services Provider

This Standard applies to all participants and their representative that interact with each other. The representatives can either be the employees --or users of a participant- or the technical users --in case of Catena-X the EDCs- of a participant.

1.2 Context

This section is non-normative

Standardization of the digital identity of technical users and employees who are bound to the company they operate for. The goal is to protect data. It ensures that permissions and users can be managed in all systems and applications.

1.3 Conformance

This section is non-normative

As well as sections marked as non-normative, all authoring guidelines, diagrams, examples, and notes in this specification are non-normative. Everything else in this specification is normative.

The key words MAY, MUST, MUST NOT, OPTIONAL, RECOMMENDED, REQUIRED, SHOULD and SHOULD NOT in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.

1.4 Proof of Conformity

This section is non-normative

All participants and their solutions will need to prove they conform with the Catena-X standards. To validate that the standards are applied correctly, Catena-X employs Conformity Assessment Bodies (CABs).

A test bed must be set up, to prove the correctness of the data provisioning. A generic test set of data must get processed, to prove the expected results.

1.5 Terminology

This section is non-normative

Additional terminology used in this standard can be looked up in the glossary on the association homepage.

2. Main Content

This standard is not certifiable yet (only release 3.1 onwards)

Core Service provider MUST proof that they apply to the OIDC standard found on the spec Specifications | OpenID to manage the identities and access policies described in CX - 0015 IAM & ACCESS CONTROL PARADIGM FOR USERS AND CLIENTS which

  • must be reachable by other partners
  • ownership must be verifiable

Core Service provider MUST prove that they provide a managed identity solution based on OIDC. Core Service provider MUST prove that they make the use for a self-hosted IdP based on OIDC possible for any participant.  If a core service provider provides an OIDC service he MUST prove that every customer has its own delimited area for his users and that no users of any customer has access to any data of another customer. The users of a specific customer must be assignable to only the customer they belong to.

To validate these criteria for the OIDC service please collect the following documents:

  • Arch42 Documentation explaining the architecture, access management and process flows of the implementation
  • The URI / URL of the OIDC instance

Hand this documentation to the conformity assessment body

An operating environment which provides an OIDC service SHOULD operate an OIDC instance that supports Attribute Based Access Control described in the following standard [Guide to Attribute Based Access Control (ABAC) Definition and Considerations (nist.gov)]

A technical user (e.g. EDC) MUST provide at least the BPN of the Data Consumer/ Producer as an attribute inside the OIDC token at any interaction.

To validate these criteria for the OIDC service please collect the following documents:

  • Arch42 Documentation explaining the architecture, access management and process flows of the implementation

Hand this documentation to the conformity assessment body
