MVP 0.1

Metadata Management

  • Add/Remove metadata (endpoint) for the entire federation
    • SSP: feeds into the configuration of Metarefresh
    • SaToSa: ?
  • Add/Remove metadata (endpoint) for individual SPs/IdPs

Relation Management

  • Select a SP to make it 'active'
    • Attribute Release Policy - Only allow REFEDs entity categories (anonymous, pseudonymous, personalized, R&S)
  • Select an IdP to make it 'active'
    • Requested attributes - Select which entity category to request.

My Metadata

Setup user facing aspects of proxy

  • Displayname
  • Supported entity categories
  • Logo


Features for a Later Version

Assumptions

  • We assume the number of connected entities is less than X (<50)

Open Question

  • Do we have 1 entity endpoint (so only the whole proxy), or do we publish separate endpoints for each and every entity we have connected?

Proposed Features

To be prioritised for an MVP

  • Translating between SAML and OIDC

Audit trail

"Proxy Wizard"

  • Ability to configure entities preloaded into the proxy based on entity federation metadata

Proxy Administration

  • Local accounts and roles? Or a single locally-managed admin user?

Entity management

  • Configuration of SAML IdP
    • Select entity which exist based on federation metadata
  • Configuration of SAML SP
  • Configuration of OIDC OP
  • Configuration of OIDC RP
  • Generic entity configuration management
    • Export/import of config items/entities
    • Copy/delete (copy as poor man's versioning, should it also work on groups of items)
    • Editing of entities in the GUI (common configuration items, protocol specific features)
    • Raw config edit
      • Is the GUI a facade that allows only basic configuration for beginners? If so, how do we represent more complicated valid configs that were created manually?
      • What happens if the config is broken by the user's manual changes? Display an error in the GUI and allow rollback to the previous version?
    • Apply config
    • Git config save
    • Generic post processor for configs, could be used to implement configuration deployment and activation and Git push
  • Management of individual IDPs/Authorisation Servers/OPs and SPs/RPs/clients within the SP proxy
  • Config checks (could also be one of the post-processors)
  • Versioning
  • Rollback from Git (Git config restore)
  • Topology graph
  • Management of multiple proxy instances
  • Management of proxy (related) data for individual entities
  • Entity lifecycle (expressed as states in the GUI? - what is the consequence of being in a certain state?)
    • Draft
    • Test
    • Production
    • Support for parked entities/configs
    • Logically deleted

Other

  • GUI for internal admin of the proxy (for key internal settings apart from managed services' configs)
  • Federation/eduGAIN support
  • Additional support for federated identity management - what specifically?
  • API to access/edit service configuration/history???
  • Validation of encryption and signatures of entities and their messages
  • Enforcement of authentication and authorisation policies - defined locally or by IdPs?
  • Integration with MFA by the proxy
  • Reporting and analytics - (sounds like an expansion of auditing - correctly chosen audit data and format might make this easier)
    • Statistics
    • Issues
    • Events/logs
  • Step back/forward during config changes (Step-by-step wizard for adding a new entity/item)
  • Dynamic updates to the configuration without requiring a full restart of the proxy service (GUI is apart from proxy services)

Managing (meta)data exchange

  • Management of attribute filtering between IDPs and SPs?
  • Management of mapping of attributes
  • Attribute transformation rules?
  • Setting of attribute values - for which entities?

Key concepts and their (alternative) names

These suggestions are for now mostly SAML flavoured to suit the target users:

  • Identity provider - IdP or OP (OpenID Provider), while Authorisation Server is a more specific role
  • Service provider - SP or RP/client ("client" is rather an OAuth2 term and is too overloaded)
  • Entity - Identity provider or service provider
  • Identity proxy - For now this, or "SP proxy", not "proxy" nor "client proxy". Consider "Identity Broker" to make this more general?
  • Configuration - settings (in a text file, optionally in a GUI) for an identity provider, service provider or SP proxy

  • Identity Federation - technical and organisational arrangement connecting multiple identity providers (IdPs) and service providers (SPs) to allow users to authenticate and access resources across different domains with a single set of credentials.

  • ...

Consider whether to use separate terminological "branches" for OIDC/SAML - specific names or conflate them into a unified terminology?

  • No labels
