Shibboleth Architecture

Shibboleth Architecture -Managing Trust Federation Attribute Server Shib engine Browser Target Web Server Origin Site Target Site

Milestones § Project formation - Feb 2000 Stone Soup § Process - began late summer 2000 with bi-weekly calls to develop scenario, requirements and architecture. § Linkages to SAML established Dec 2000 § Architecture and protocol completion - Aug 2001 § Design - Oct 2001 § Coding began - Nov 2001 § Alpha-1 release – April 24, 2002 § Open. SAML release – July 15, 2002 § v 1. 0 April 2003 § v 1. 1 July 2003 § V 1. 2 April 2004 § V 2. 0 likely end of the major evolution

Shibboleth Status § Open source, privacy preserving federating software § Being very widely deployed in US and international universities § Target - works with Apache(1. 3 and 2. 0) and IIS targets; Java origins for a variety of Unix platforms. § V 2. 0 likely to include portal support, identity linking, non web services (plumbing to GSSAPI, P 2 P, IM, video) etc. § Work underway on intuitive graphical interfaces for the powerful underlying Attribute Authority and resource protection § Likely to coexist well with Liberty Alliance and may work within the WS framework from Microsoft. § Growing development interest in several countries, providing resource manager tools, digital rights management, listprocs, etc. § http: //shibboleth. internet 2. edu/

Adoption § Over 40 + universities using it for access to OCLC, JSTOR, Elsevier, Web. Access, Napster, etc. § Common status is “moving into production” § The hard part is not installing Shibboleth but running “plumbing” to it: directories, attributes, authentication § Deployments in Europe and the UK § Development efforts broadening to the UK and Australia § Likely to be the interrealm aspect to Sakai, Lionshare, video

Federated administration § Given the strong collaborations within the academic community, there is an urgent need to create inter-realm tools, so § Build consistent campus middleware infrastructure deployments, with outward facing objectclasses, service points, etc. and then § Federate (multilateral) those enterprise deployments with interrealm attribute transports, trust services, etc. and then § Leverage that federation to enable a variety of applications from network authentication to instant messaging, from video to web services, from p 2 p to virtual organizations, etc. while we § Be cautious about the limits of federations and look for alternative fabrics where appropriate.

Federations § Associations of enterprises that come together to exchange information about their users and resources in order to enable collaborations and transactions § Enroll and authenticate and attribute locally, act federally. § Uses federating software (e. g. Liberty Alliance, Shibboleth, WS-*) common attributes (e. g. edu. Person), and a security and privacy set of understandings § Enterprises (and users) retain control over what attributes are released to a resource; the resources retain control (though they may delegate) over the authorization decision. § Several federations now in construction or deployment

In. Common federation § Federation operations – Internet 2 § Federating software – Shibboleth 1. 1 and above § Federation data schema - edu. Person 200210 or later and edu. Org 200210 or later § Becomes operational April 5, with several early entrants to help shape the policy and membership issues. § Precursor federation, In. Queue, has been in operation for about six months and will feed into In. Common § http: //www. incommonfederation. org

In. Queue Origins 2. 12. 04 §Rutgers University §University of Wisconsin §New York University §Georgia State University §University of Washington §University of California Shibboleth Pilot §University at Buffalo §Dartmouth College §Michigan State University §Georgetown §Duke §The Ohio State University §UCLA §Internet 2 §Carnegie Mellon University §National Research Council of Canada §Columbia University §University of Virginia §University of California, San Diego §Brown University §University of Minnesota §Penn State University §Cal Poly Pomona §London School of Economics §University of North Carolina at Chapel Hill §University of Colorado at Boulder §UT Arlington §UTHSC-Houston §University of Michigan §University of Rochester §University of Southern California

In. Common Management § Operational services by I 2 • Member services • Backroom (CA, WAYF service, etc. ) § Governance • Executive Committee - Carrie Regenstein - chair (Wisconsin), Jerry Campbell, (USC), Lev Gonick (CWRU), Clair Goldsmith (Texas System), Mark Luker (EDUCAUSE), Tracy Mitrano (Cornell), Susan Perry (Mellon), Mike Teetz, (OCLC), David Yakimischak (JSTOR). • Project manager – Renee Frost (Internet 2) § Membership open to. edu and affiliated business partners (Elsevier, OCLC, Napster, Diebold, etc…) § Contractual and policy issues being defined now… § Likely to take 501(c)3 status

Trust in In. Common - initial § Members trust the federated operations to perform its activities well • The operator (Internet 2) posts its procedures, attempts to execute them faithfully, and makes no warranties • Enterprises read the procedures and decide if they want to become members § Origins and targets trust each other bilaterally in out-ofband or no-band arrangements • Origins trust targets dispose of attributes properly • Targets trust origins to provide attributes accurately • Risks and liabilities managed by end enterprises, in separate ways

In. Common Trust - ongoing § Use trust Build trust cycle § Clearly need consensus levels of I/A § Multiple levels of I/A for different needs • Two factor for high-risk • Distinctive requirements (campus in Bejing or France, distance ed, mobility) § Standardized data definitions unclear § Audits unclear § International issues

The potential for In. Common § The federation as a networked trust facilitator § Needs to scale in two fundamental ways • Policy underpinnings need to move to normative levels among the members; “post and read” is a starting place… • Inter-federation issues need to be engineered; we are trying to align structurally with emerging federal recommendations § Needs to link with PKI and with federal and international activities § If it does scale and grow, it could become a most significant component of cyberinfrastructure…

Beyond web services… § Federated security services • Collaborative incident correlation and analysis • Trust-mediated transparency and other security-aware capabilities § Federated extensions to other architectures • Lionshare project for P 2 P file sharing • IM • Federated Grids

Next Steps § Shibboleth • The GUI’s – Sys. Priv, Autograph, My. Space • Linked identities • New development model – international participation § In. Common • Policy development • Membership § Distnguishing buyers clubs from federations

GUI’s to manage Shibboleth

Sys. Priv ARP GUI § A tool to help administrators (librarians, central IT sysadmins, etc) set attribute release policies enterprisewide • For access to licensed content • For linking to outsourced service providers • Has implications for end-user attribute release manager (Autograph) § GUI design now actively underway, lead by Stanford § Plumbing to follow shortly

End-user attribute release manager (Autograph) § Intended to allow end-users to manage release policies themselves and, perhaps, understand the consequences of their decisions § Needs to be designed for everyone even though only 3% will use it beyond the defaults. § To scale, must ultimately include extrapolation on settings, exportable formats, etc.

Privacy Management Systems

Personal Resource Manager

Virtual Organizations §Geographically distributed, enterprise distributed community that shares real resources as an organization. §Examples include team science (NEESGrid, HEP, BIRN, NEON), digital content managers (library cataloguers, curators, etc), life-long learning consortia, etc. §On a continuum from interrealm groups (no real resource management, few defined roles) to real organizations (primary identity/authentication providers) §Want to leverage enterprise middleware and external trust fabrics

Virtual organizations § Need a model to support a wide variety of use cases • Native v. o. infrastructure capabilities, differences in enterprise readiness, etc. • Variations in collaboration modalities • Requirements of v. o. ’s for authz, range of disciplines, etc § JISC in the UK has lead; solicitation is on the streets (see (http: //www. jisc. ac. uk/c 01_04. html); builds on NSF NMI § Tool set likely to include seamless listproc, web sharing, shared calendaring, real-time video, privilege management system, etc.
