2005 © SWITCH Perspectives of Integrating AAI with Grid in EGEE-2 Christoph Witzig Amsterdam, October 17, 2005

2005 © SWITCH 2 Outline Introduction – Overview of SWITCH – SWITCH activities in AAI and Grid SWITCHaai: The Swiss Shibboleth-based AAI – How it works – Shibboleth concepts EGEE security framework – Introduction EGEE – How it works – Grid security concepts SWITCH proposal for interoperability Shibboleth - gLite Related efforts Summary

2005 © SWITCH 3 Introduction SWITCH has four strategic business areas – Network: operating the Swiss Research and Eduction network – Domain name registration for.ch and.li – Security  Operates (among other things) SWITCHpki – NetServices  providing services on top of the network for academic users NetServices – Video conferences, streaming technologies, support for (physical) mobility – SWITCHaai: Shibboleth-based AAI for the Swiss academic sector – Grid: targeted Grid services as new strategic direction  There is no Swiss grid program  Various grid efforts at some universities Introduction

2005 © SWITCH 4 SWITCHaai = federated, national, Shibboleth-based authentication and authorization infrastructure (AAI). SWITCHaai Main efforts: > 110’000 users (  50%) of the Swiss higher education sector are currently “AAI-enabled”. Federally funded cooperation projects will complete the national roll-out and increase the number of new resources. Define cooperation with other federations. Develop accounting (AAAI) services. Introduction

2005 © SWITCH 5 Grid support = new strategic direction: national AAI-enabled grid infrastructure in Switzerland. SWITCH Activities in Grid Computing Two main strategic efforts: Within the context of EGEE-2 we want to add interoperability between Shibboleth and the gLite middleware stack. Within the national context we want to work together with our partners (universities, computing centers) to build up such a national grid infrastructure based on the AAI-enabled gLite middleware. Introduction

2005 © SWITCH 6 Disclaimer Decision of EU regarding EGEE-2 proposal is pending Assuming a positive answer from the EU EGEE-2 will start in April 2006 and last for two years Introduction

2005 © SWITCH 7 University A Library B University C The World without AAI Student Admin Web Mail e-Learning Literature DB e-Learning Research DB Authorization User Administration Authentication Resource Credentials  Tedious user registration at all resources  Unreliable and outdated user data at resources  Different login processes  Many different passwords  Many resources not protected due to difficulties  Often IP-based authorization  Costly implementation of inter-institutional access e-Journals SWITCHaai

2005 © SWITCH 8 University A Library B University C AAI The World with AAI Student Admin Web Mail e-Learning Literature DB e-Learning Research DB Authorization User Administration Authentication Resource Credentials  No user registration and user data maintenance at resource needed  Single login process for the users  Many new resources available for the users  Enlarged user communities for resources  Authorization independent of location  Efficient implementation of inter-institutional access e-Journals SWITCHaai

2005 © SWITCH 10 Shibboleth Concepts SWITCHaai Based on SAML Initial focus on Web-based resources

2005 © SWITCH 11 EGEE: Enabling Grids for E-sciencE EU sponsored grid project within FP6 – Funding : 32 Mio € – Proposal for second phase submitted ( ) Emphasis is on – not software development – operating a production grid and supporting the end-users – Hardening, re-engineering and extending existing middleware functionality Large collaboration – > 180 sites – 20 VO’s – > 800 registered users EGEE

2005 © SWITCH 14 Interoperability Shibboleth - gLite Part of EGEE-2 proposal (by SWITCH in EGEE NREN Federation) Focus is on – Interoperability (NO replacement for X.509) – Specific for EGEE infrastructure (VOMS etc) – Integrate, re-use, re-engineer existing code, write new code only as needed Key Concepts: – Home institution of the user should be the Identity Provider – Home institution provides some attributes – But VO is needed for (grid specific) attributes Proposal of doing work in three phases: – Two initial, shorter phases with the intention of hooking SWITCHaai up to the grid with a minimal amount of effort to have a working system – A third phase with adding support for SAML at the resource (service provider) Interop. Shib gLite

2005 © SWITCH 15 Phase 1 and 2 Note: no changes at the Resource Work is more than just software (policies) Interop. Shib gLite

2005 © SWITCH 16 Access for Grid Users to Shib SP Intention: add “symmetry” between enabling access for Shib and grid users Test-bed between SWITCH and INFN in 2006 Interop. Shib gLite

2005 © SWITCH 17 SAML Support at the Resource Third (and main) phase of project Goal: Support for SAML for authentication and authorization without relying on X.509 (on a configurable basis) Should be based on SAML2 – Supports ECP Profile (constrained delegation) – Will be used in Shibboleth 2 Interop. Shib gLite

2005 © SWITCH 18 Related Efforts GridShib: – Emphasis is on providing attributes based authorization – Based on GT4 and Shib 1.3 – Beta version available since Sept 05 OGSA authZ working group: – Defines specifications for basic interoperability and pluggability of authorization modules in OGSA framework Condor Shibboleth Merger Project – Phase I: Shib enabled Condor web portal – Phase II: Shib enabled Condor fat client Shibboleth - grid activities in UK – ESP-Grid – Further work is planned (JISC) to look at CA/Shib issues Issue of attribute management between IdP and VO (e.g. Signet) Related Efforts

2005 © SWITCH 19 Summary There is interest and activity for interoperability AAI / Shibboleth - grid – But X.509 is still the standard security mechanism for grids (and likely to remain so for quite some time) – Issue is not only authentication but also attribute sharing between IdP, VO, SP – Opportunity and need for NREN and Grid communities to interoperate GridShib: – beta version available – GT4 and Shib 1.3 SWITCH participates in EGEE-2 to add interoperability Shibboleth - gLite – Pending approval by EU (expected in November) – We are interested in learn about other activities, share experiences and coordinate efforts
