  1. Research and NeSC Applications Prof Richard Sinnott Technical Director National e-Science Centre r.sinnott@nesc.gla.ac.uk 26th October 2006

  2. The Context • There are many Grids • There are many ways to build Grids • There are many different middleware competing in this space • People say Grid in grants and then build web services because Grid middleware is too hard • There are many agendas • big business, academic, … • There are many moving targets • changing middleware, changing standards, changing sciences resources/questions/funding streams… • There is a lot of hype • There is a lot of money available • There are lots of projects and big scientific challenges • There is an urgent need to build user communities • There needs to have much more research pull than middleware push • … there are many more things that could go here!

  3. Online System Tier2 Centre ~1 TIPS Caltech ~1 TIPS Tier2 Centre ~1 TIPS Tier2 Centre ~1 TIPS Tier2 Centre ~1 TIPS HPSS HPSS HPSS HPSS HPSS 1 TIPS is approximately 25,000 SpecInt95 equivalents Physicists work on analysis “channels”. Each institute will have ~10 physicists working on one or more channels; data for these channels should be cached by the institute server Pentium II 300 MHz Pentium II 300 MHz Pentium II 300 MHz Pentium II 300 MHz Data Grids for High Energy Physics ~PBytes/sec ~100 MBytes/sec Offline Processor Farm ~20 TIPS There is a “bunch crossing” every 25 nsecs.

  4. Challenges of NanoCMOS Design OMII-UK middleware (workflows, security, data management, resource management, …) 3D + Statistical

  5. The e-Health Future… Globus/WS- middleware (fine grained security, data access/integration, exponential data growth, keep it simple!) Tissues Cell Organs Protein functions Protein Structures Organisms Physiology Gene expressions Populations Nucleotide structures Cell signalling Nucleotide sequences Protein-protein interaction (pathways)

  6. NeSC Research… • Most NeSC Glasgow research is on security and ease of use across various application domains • NeSC Edinburgh focus is on middleware development especially Grid data access/integration (OGSA-DAI, DAIT, OMII-UK, eDIKT), high performance networking, data curation ….

  7. Ease of Use • (…and setting the scene for some of the later demonstrations) • For Grids/e-Research to be truly successful • have to be made as seamless to access and use as the internet • Forget training, education for some (most?) users! • have to be based on research pull and not middleware push • experiences in various projects have shown that users don’t like digital certificates • The majority most certainly won’t jump through hoops to get on the Grid

  8. Single Sign-On • X.509 certificate based PKI common to many Grid efforts (including UK) • Step 1. • Get a certificate • Step 2. • Get your DN registered at places you expect to use • Step 3. • Read the manuals (Globus, gLite, …) for how to submit/run a job

  9. Step 1 • In UK e-Science community X.509 PKI based on centralised CA with direct single hierarchy to users • Typical scenario for getting Grid certificate CA 2. Check detailsof request • Request certificate • (www.grid-support.ac.uk/ca) 4. Download and install certificate in browser 5. Download and install CRL RA 3. Ok? User ? 6. Export certificate to various formats e.g. as Grid certificate $> openssl pkcs12 -in cert.p12 -clcerts -nokeys -out usercert.pem!!!! This is off-putting for end users!!! Typically not available on Windows!!! Root access? Local sys-admin?

  10. But… • Identity management issues • Certificate Revocation Lists • When revoked? By whom? How timely? • Strong passwords for private keys • Users write them down, share them, forget them • Privilege Management • Numerous domains where never get access to local account to “do stuff” • User classification • Tinkerers vs much larger e-Research Community • they want services to point their browser at and point click to run things on the Grid • I don’t want an account on a cluster to compile/run code, I’m a biologist who wants to run BLAST on a free National Grid resource

  11. As a result… • ~3500 UK e-Science certs • 1000 for Manchester cluster • But over 3 Million Athens accounts in UK HE/FE • Iceberg is not to scale!!!!

  12. How Can we Improve Things? • We don’t want each domain reinventing their own security solutions • Best to exploit local authentication • Sites know best if users still at institution and are best placed to state what their privileges are/should be

  13. Introducing Shibboleth • Shibboleth (http://shibboleth.internet2.edu) Definition Shibboleth [Hebrew for an ear of corn, or a stream or flood] 1. A word which was made the criterion by which to distinguish the Ephraimites from the Gileadites. The Ephraimites, not being able to pronounce sh, called the word sibboleth. See --Judges xii. 2. Hence, the criterion, test, or watchword of a party; a party cry or pet phrase. ] • Shibboleth will replace Athens as access mgt system across UK academia • Federations based on trust • or more accurately trust but verify • numerous international federations exist MAMS, SWITCH, HAKA, SDSS…

  14. 4. Home site authenticates user 3.User selects their home institution 2. Shibboleth redirects userto W.A.Y.F. service LDAP • User points browser at Grid resource/portal (or non-Grid resource) Typical Shibboleth Scenario Identity Provider AuthN Home Institution Federation Service provider 5. User accesses resource W.A.Y.F. User Grid resource / portal

  15. It’s a start, but… • Benefit from local authentication but really want finer grained control… • I know you have authenticated, but I need to know that you have sufficient/correct privileges to access my VO resources • can also return various other information needed to support authorisation decisions

  16. Authorization Technologies • Various technologies for authorization including • PERMIS • PrivilEge and Role Management Infrastructure Standards Validation • http://www.permis.org • Community Authorisation Service • http://www.globus.org/security/CAS/ • AKENTI • http://www-itg.lbl.giv/security/akenti • CARDEA • http://www.nas.nasa.gov/Research/Reports/Techreports/2003/nas-03-020-abstract.html • VOMS • http://hep-project-grid-scg.web.cern.ch/hep-project-grid-scg/voms.html • At NeSC we have been working extensively with PERMIS

  17. Role Based Access Controls • Basic idea is to define: • roles applicable to specific VO • roles often hierarchical • Role X ≥ Role Y ≥ Role Z • Manager can do everything (and more) than an employee can do who can do everything (and more) than a trainee can do • actions allowed/not allowed for VO members • resources comprising VO infrastructure (computers, data resources etc) • A policy then consists of sets of these rules • { Role x Action x Target } • Can user with VO role X invoke service Y on resource Z? • Policy itself can be represented in many ways, e.g. XML, XACML, … • Tools available for policy editing, associating users with roles, signing policies etc • Policies stored as attribute certificates in LDAP server • (New tools/wizards presented at OGF18 Washington)

  18. 4. Home site authenticates user and pushes attributes totheservice provider 3.User selects their home institution 2. Shibboleth redirects userto W.A.Y.F. service LDAP 1. User points browser at Grid resource/portal Finer Grained Shibboleth Scenario Identity Provider Service provider Shib Frontend AuthN Home Institution 6. Make final AuthZ decision Federation Grid Application 5. Pass authentication info and attributestoauthZ function W.A.Y.F. User Grid Portal

  19. Ok, but… • I can do authorisation but I want single-sign on to lots of distributed resources across different organisations (aka Virtual Organisations in Grid speak) • Browser allows to keep session information so can access other resources without signing in again • Provided authorisation information valid for different service providers • Each service provider completely autonomous • Can configure attribute release/attribute acceptance policies per identity provider/service provider
