1 EMI INFSO-RI-261611 Session Summary AAI Needs for DCIs John White, HIP Christoph Witzig, SWITCH john.white@cern.ch christoph.witzig@switch.ch

2 EMI INFSO-RI-261611 Outline Introduction Requirements and Plans of different Communities Summary Findings Note: – authN = authentication – authZ = authorization

3 EMI INFSO-RI-261611 Introduction AAI = authentication and authorization infrastructure DCI = distributed computing infrastructure AAI-DCI Workshop – organized as part of EMI workplan – Indico: https://www.egi.eu/indico/sessionDisplay.py?sessionId=11&slotId=0&confId=48 - 2010-09-14 https://www.egi.eu/indico/sessionDisplay.py?sessionId=11&slotId=0&confId=48 - 2010-09-14 – Milestone document to follow EMI needs to provide harmonized middleware stack – Provide user-friendly interface, especially for authenticating to an infrastructure

4 EMI INFSO-RI-261611 Questionnaire to Communities (1/2) Targeted a set of communities with dependency to an (emerging) infrastructure – Many tied to an ESFRI project All are rather large communities distributed over many European countries Most are rather early in their lifecycle

5 EMI INFSO-RI-261611 Questionnaire to Communities (2/2) 1.How are users authenticated? 1.Which credentials are in use? 2.How is the user vetting done? 2.Is there a link to national identities? 3.Which types of resources are in use? How are users authorized? 1.Resources access through Grid? 2.Resources accessed without Grid? 4.Where does project want to be in ~5 years? 5.Are users and resource owners happy with current authN and authZ schemes?

6 EMI INFSO-RI-261611 The vision …

7 EMI INFSO-RI-261611 … and the reality

8 EMI INFSO-RI-261611 Earthscience Grid (1/2) Horst Schwichtenberg, Fraunhofer Institute Access to data is central for ES – Archived sensor data or derived data from multiple sources and in multiple formats  different providers and different systems Geographical Information System (GIS) – WS Specification from Open Geospatial Consortium (OGC)  no specification for authN/authZ – Work in progress HTTP authN, HTTP cookies, SSL X.509, SAML, Shibboleth and openID

9 EMI INFSO-RI-261611 Earthscience Grid (2/2) Requirements: – Protect data down to the single user – Federated identity and single sign-on SAML and OAuth, WS-* protocols SSO based on Shibboleth and OpenID – Science gateways to provide access to computing infrastructure (EGI) in the background Automatic certificate generation – Data centers need to protect licensed data and code

10 EMI INFSO-RI-261611 Biomedical Community (1/2) Key requirements: – Preserve patient privacy – Copyrighted data processing tools Current authN: – X.509 (grid users and French Health Professional smartcards) Resources: – EGI storage (SRM) and external data repositories – Web-based resources

11 EMI INFSO-RI-261611 Biomedical Community (2/2) Goal in ~5 years: – Homogenous AA handling in Grid services – Access control to relational and semantic stores User’s view: – AA scheme is irrelevant. Only functionality matters. – Dedicated solutions often needed in Life Sciences.

12 EMI INFSO-RI-261611 CLARIN (1/2) Dieter Van Uytvanck, MPI for Psycholinguistics Aim: – Provide language resources and technologies for humanities and social sciences Typical use-case: – On basis of browsing catalogues and/or searching through data create a virtual collection and process it through work flows using web services

13 EMI INFSO-RI-261611 CLARIN (2/2) Long term AA objectives: – Rely on user’s home organization of national AAIs for establishing trust  SAML, Shib – CLARIN as legal entity to sign contracts with national identity federations – Rely on eduGAIN to provide trust between national AAIs Issues raised: – License acceptance must be solved (special license service) – Multi-level WAYFs and attribute release consent confusing for the user

14 EMI INFSO-RI-261611 Photon Facilities (1/2) Hans Weyer, PSI Environment: – Photon facilities with wide range of research areas and ~30’000 visiting scientists / year – ~15 synchrotrons in EU, often national facilities Facilities partly co-operating, partly competing

15 EMI INFSO-RI-261611 Photon Facilities (2/2) AA Ansatz: “Umbrella” – Use EU wide, central user identification Username, pwd, email, birthday – Local management of additional, site-specific attributes Phone, registrations, facility roles, proposals – Based on SAML – Note: Do not plan to use national AAIs for authN

16 EMI INFSO-RI-261611 ILL – Neutron Science Neutron facility, very diverse user community Need federated authentication and management of user’s attributes authN should provide access to – Web based applications – Network connection – Workstation access

17 EMI INFSO-RI-261611 ELIXIR ESFRI BMS Project coordinated by EBI Very large user community (~1 mio users) Provide access to life science data (genoms, …) for many different sciences Users are not authenticated many users find authN unacceptable Sensitive data (e.g. patients data) handled through a special procedures (data custodian)

18 EMI INFSO-RI-261611 Lifewatch Axel Poigné, Fraunhofer Still design phase – no decisions taken Present thoughts: – X.509 not appropriate – Use Shibboleth Credential translation for access to Grid OpenID complementary

19 EMI INFSO-RI-261611 HEP Maarten Litmaath, CERN Key technologies: – X.509, IGTF – VOMS Issues with Grid security – Certificates are difficult for users to handle – Proxy issues, use of primary FQANs – etc

20 EMI INFSO-RI-261611 Other talks Moonshot: D.Kouril, CESNET Goal: enable use of identity federations and SAML for non-web applications Target core internet protocols: SSH, SMTP, IMAP, NFSv4, HTTP… Started spring 2010 Presentations of – IGI: V.Ciaschini, INFN – UK NGI, C. Devereux, STFC

21 EMI INFSO-RI-261611 Summary Findings (1/2) Different communities do have different requirements User-centric view is mandatory – Very large and very diverse user communites – Many users have “modest IT knowledge” and “limited enthusiasm for complex solutions”

22 EMI INFSO-RI-261611 Summary Findings (2/2) Key technologies – Federated identity / SAML / Shibboleth With / without leveraging national AAIs – X.509 still basis for Grid technology – SLCS, MICS CA – Need novel ways to bridge security domains ECP support in Shibboleth (useful for portals  Swiss Grid Portal project) Security token service (work item in EMI) Pseudonymity service (EMI) Moonshot Key requirement for AA solutions: – Standards-based, interoperable

23 EMI INFSO-RI-261611 Should be aware of time lag between development and deployment But if not all, then most roads lead to Rome
