1. The Basics of Federated Identity

2. Overview of Federated Identity and Grids Workshop Session 1 - for all Basics and GridShib Session 2 – more for developers Architecture and attributes Panel of developers Session 3 – more for deployers State of practice in federations Panel of deployers Session 4 – a focus on VOs and federated identity Privilege management VO services

3. Basics Types of identity The basics of federated identity Enterprise middleware Attribute and entitlement orientation Federating software The trust fabrics Current status and uses Applications R&E, Gov Corporations and federations Internal, Sector, and Participation in R&E Policies and Peering

4. Three Types of Identity Global basic identity Passport, drivers license, qualifying X.509 cert Federated enterprise Enterprise provides identity management for its users Enterprises federate to build inter-realm trust and identity; federations peer Peer to peer Self asserted, individual to individual Lots of approaches, many clever Hybrids and others

5. A Word About the Other Two… Global government issued Qualifying certs, birth certificates, passports, drivers licenses, etc. Strength of identity proofing varies widely Lurching along Peer to peer is very hot but not yet gelling Lots of different identifiers (email addresses, urls, aliases) Lots of different trust builders (read my site, special delivery, friends of friends, etc.) Workshops every two months, may converge soon on just two - three approaches.

6. And Some Hint of Layering User-centric Identity wants to integrate all types of identity At storage level Maybe not the actual credentials, but a store of pointers At user interface level The brainmap and the presentation MS Cardspace and Higgins two of the major players

7. Basics of federated identity Enterprise middleware Attribute and entitlement orientation Federating software The trust fabrics

8. Enterprise Middleware Provide common services for many applications, network layer services (wireless access, lambdas, etc.) Directories and metadirectories Authentication and Single Sign-On Lifecycle Identity Management Services To students, faculty, staff, alumni, contractors, guests, academic medical centers… Group and privilege management May eventually include workflow, DRM, etc Business Processes and legacy apps that feed the infrastructure and draw from it.

11. Relative Roles of Signet & Grouper Grouper Signet RBAC (role-based access control) model Users are placed into groups (aka roles) Privileges are assigned to groups Groups can be arranged into hierarchies to effectively bestow privileges Grouper manages, well, groups Signet manages privileges Separates responsibilities for groups & privileges

12. Attributes Attributes have well-defined syntax and semantics across the relevant community Typically have controlled vocabulary of possible values, though some values are open-ended in meaning. May be personally identifiable or more general Exist in many forms, from storage (LDAP) to transport (SAML, attribute certificates) to metadata (OIDs, rfcs,etc.) Come from sources of authority Are often used to determine access In shifting the focus from identity to attributes lies the ability to preserve privacy

13. Entitlements A particular and common attribute, giving a person permissions to use certain resources Are often delegated, constrained, time-limited, etc. Can be managed, at enterprise and end-user levels, with a privilege manager (e.g. Signet) Controlled complexity Have much to offer VOs in moving from identity- based authorization to better models

14. Federating Software Almost all software built on OASIS SAML standard. Many vendors moving towards SAML 2.0 Most R&E federations use Shibboleth 1.x or a compatible (e.g. properly configured Sun Identity Manager, A-Select, etc.) SAML and Shib have been deeply joined from the beginning (c 2000). Shared design, OpenSAML a major part of Shib, Scott Cantor (OSU) lead Shib architect and SAML 2.0 editor… SAML addresses more the bi-lateral use case; Shib the multi-lateral Apache 2.0 type license open source Shib 2.0 alpha due out in April WS-Fed, part of WS-* Proprietary MS and IBM trust framework Works well with ADFS and enterprise MS

15. Trust Fabrics Instantiate as federations, with a federated operator, frequently leveraging existing organizations Technical set of issues Versions of software Attributes Metadata exchanges Policy issues Common standards for IdM – identity proofing, acts of authentication, assignment of common attributes, etc. Governance and federation operations

18. Federated Applications Mostly access controls to content The first shibbed collaborative apps are appearing… Several wikis Digital repositories such as DSpace and Fedora Learning Management Systems such as WebCT IM, p2p fileshare (Lionshare), CVS Grid-Shib integration in several ways SIP based tools (videoconferencing, audioconferencing) within reach Bootstrapping from duct tape sometimes a problem

19. Current State – R&E R&E federations moving forward rapidily in many countries, including the US, UK, France, Germany, Sweden, Australia, Switzerland, Norway, Netherlands, Finland, Denmark, etc. State university systems federate – Texas, California, Maryland, Cal State, Ohio, etc. Use primarily is access to content and services, but eScience, collaborative apps and virtual organizations are on the map In the US, InCommon has approximately forty members.

20. Current State - Gov Several national governments are developing federations of agencies and offering services to external users Within the US, several national governments are developing federations GSA EAuthentication NSF NIH Close and strange working relationships with InCommon

21. Corporations and Federations Internal use of federated id Vertical sectors Participation in other sectors Content providers Apps for education The consumer marketplace

22. Peering and Confederation For federations to scale – internationally, across vertical sectors, and in size, some forms of interactions are necessary Peering involves agreements between federations on common attributes, levels of assurance, metadata, economics, privacy, etc. Confederation, a union of national federations, is useful in situations such as Europe with many similar but distinct federations Other forms, such as state federations relating to InCommon, are certain to emerge.

23. Peering

24. Frontier Thoughts… Right now, federations are about identities and their attributes Could federations support collaboration fabrics? Federated group and privilege management Virtual organization support Servers and tools Workflow? Digital signatures? How much integration is too much?
