  3. Introduction LCG & EGEE David Kelsey, LCG/EGEE Security, HEPiX

  4. LCG today David Kelsey, LCG/EGEE Security, HEPiX

  5. Build a large-scale production grid service to: Underpin European science and technology Link with and build on national, regional and international initiatives Foster international cooperation both in the creation and the use of the e-infrastructure Collaboration Pan-European Grid Operations, Support and training Network infrastructure(GÉANT) The next generation of grids:EGEE Enabling Grids for E-science in Europe AHM2004, Nottingham, September 2004 - 5

  6. EGEE Activities • 48 % service activities (Grid Operations, Support and Management, Network Resource Provision) • 24 % middleware re-engineering (Quality Assurance, Security, Network Services Development) • 28 % networking (Management, Dissemination and Outreach, User Training and Education, Application Identification and Support, Policy and International Cooperation) 32 Million Euros EU funding over 2 years starting 1st April 2004 Emphasis in EGEE is on operating a production grid and supporting the end-users AHM2004, Nottingham, September 2004 - 6

  8. Security Policy David Kelsey, LCG/EGEE Security, HEPiX

  9. LCG Security Policy • During 2003/04, the LCG project agreed a first version of its Security Policy • Written by the Joint Security Policy Group • Approved by the Grid Deployment Board/PEB • A single common policy for the whole project • But does not override local policies • An important step forward for a production Grid • The policy • Defines Attitude of the project towards security and availability • Gives Authority for defined actions • Puts Responsibilities on individuals and bodies • Now being used by EGEE and (some) national Grids David Kelsey, LCG/EGEE Security, HEPiX

  10. LCG Policy GOC Guides New since Oct 2003 picture from Ian Neilson Incident Response Certification Authorities Audit Requirements Usage Rules Security & Availability Policy Application Development & Network Admin Guide User Registration & VO Management http://cern.ch/proj-lcg-security/documents.html David Kelsey, LCG/EGEE Security, HEPiX

  11. Security Procedures & Operations David Kelsey, LCG/EGEE Security, HEPiX

  12. Security Procedures • Incident Response • Open Science Grid leading this area • See talks in Friday morning’s Operations session • LCG/EGEE Operational Security • Operational Security Coordination Team (OSCT) • Again: see Friday’s talk • User Registration & VO Management • Requirements for 4 LHC Experiments • Presented at May 2004 (Edinburgh) HEPiX (M.Dimou) David Kelsey, LCG/EGEE Security, HEPiX

  13. User Registration and VO Membership Management • Requirements document (V2.7) • https://edms.cern.ch/document/428034 • approved by GDB in May 2004 • Task force created to propose the solution • Many discussions with CERN HR, User Office, Experiment Secretariats, VO managers, … • Recent Meeting at CERN • 15-17 September, 2004 http://cern.ch/dimou/lcg/registrar/TF/meetings/2004-09-15/ • Technical solution now agreed David Kelsey, LCG/EGEE Security, HEPiX

  14. User Registration (1) • Every user (4 LHC expts) must register in CERN HR db first • Already true for the majority • Advantages of using existing procedures • No duplication of effort or personal data • External users (e.g. people never coming to CERN) and short-term users (e.g. external summer students) • Need a simple, speedy and robust procedure • Non-VO people • e.g.testers/experiment independent people • must register in CERN HR (e.g. via LCG/IT) • Eventual aim is to use the experiment participation end-date in CERN HR to trigger immediate suspension from the VO David Kelsey, LCG/EGEE Security, HEPiX

  15. User Registration (2) • VO registration expiry date • Not exceeding 1 year from date of VO registration • Less if institute-contract/CERN HR registration expires before then • Personal User Data will only reside in CERN HR • There is no automatic membership of VO • User has to complete a form and the VO manager has to approve • Authorized personnel at resource centres will have read access to the VO registration info David Kelsey, LCG/EGEE Security, HEPiX

  16. User Registration (3) • When VO expiry date is reached, the VO membership is immediately suspended • Advance warning will be sent to the user • There will be other possible reasons for suspension • E.g. following security problems David Kelsey, LCG/EGEE Security, HEPiX

  17. Technical Solution agreed • 15-17 Sep meeting decisions: • The VO registration database • Will be VOMRS component from US CMS VOX • VOMRS needs development to meet new requirements (FNAL working on this) • VOMRS manages the groups and roles -> VOMS • CERN is working on VOMRS interconnection to the CERN HR DB (Oracle) • The dynamic Authorization will be VOMS • Groups and roles • Non-LHC VO’s may use the VOMS-admin component (an alternative admin UI) • Time to implement not yet agreed • Aiming for early in 2005 David Kelsey, LCG/EGEE Security, HEPiX

  18. Security Technology David Kelsey, LCG/EGEE Security, HEPiX

  19. Authentication: EU Grid PMA CAs 27 Accredited CAs • Green: Accredited • Yellow: Recent approvals or still under discussion • Slovenia just approved • Austria & Bulgaria soon? Other Accredited CAs: • DoEGrids (US) • GridCanada • ASCCG (Taiwan) • ArmeSFO (Armenia) • CERN • Russia (HEP) • FNAL Service CA (US) • Israel • Pakistan “Catch-all” CAs operated by CNRS (for EGEE) US DOE (for LCG) SEE-GRID (for SE Europe) David Kelsey, LCG/EGEE Security, HEPiX

  20. AuthZ – VOMS & LCAS high frequency low frequency CA CA CA host cert(long life) service user crl update user cert(long life) VO-VOMS registration registration VO-VOMS voms-proxy-init VO-VOMS proxy cert(short life) service cert(short life) VO-VOMS authz cert(short life) authz cert(short life) authentication & authorization info LCAS David Kelsey, LCG/EGEE Security, HEPiX

  21. gLite security • Aims at being • Modular – add new modules later • Agnostic – modules will evolve • Standard – start with transport-level security but intend to move to WS-Security when it matures • Interoperable - at least for AuthN & AuthZ Applied to Web-services hosted in containers and applications (Apache Axis & Tomcat) as additional modules Security architecture: https://edms.cern.ch/document/487004/ AHM2004, Nottingham, September 2004 - 21

  22. EGEE AuthZ Policy Policy comes from many stakeholders Graphics from Globus Alliance& GGF OGSA-WG David Kelsey, LCG/EGEE Security, HEPiX

  23. Future Work • Policy • Working on more general policy (with OSG) • No longer LCG-specific • EU eInfrastructure Reflection Group (18 Nov 04) • Acceptable Use Policy and Authorization for EU eScience • Procedures • Operational Security, including Incident Response • User Registration • Technology • Authentication • Asia/Pacific & Americas PMAs being created • Credential Repositories • Authorization – dynamic role-based access control • VOMRS & VOMS • Local control and policy, e.g. via LCAS/LCMAPS • Security requirements, Operational Constraints • Very important to get Site input to operations and middleware development (all feedback is very welcome!)
