R Mollon, C Blanchet - EGEE Security Status – Biomed – Valencia, January 27th, Enabling Grids for E-sciencE INFSO-RI Bioinformatic requirements Certificate management[DONE] –For all entities (like users, services, Web portals,...) –Renew and revoke mechanisms Fine grain access to data [IN PROGRESS] –Access Control Lists (ACL) support –The owner can do modifications Data encryption [IN PROGRESS] –Long-term storage of encrypted data –Transparent (unencrypted) access for authorized users Data anonymization [STOPPED] –Medical data (analyses, diagnoses, pictures,...) –Legislation problems in France According to Biomed requirement database, and Ake Edlund, JRA3 manager

R Mollon, C Blanchet - EGEE Security Status – Biomed – Valencia, January 27th, Enabling Grids for E-sciencE INFSO-RI EGEE Security Overview (1) Main high-level security functionalities : –Single Sign On (SSO) [DONE]  A unique authentication to access to the entire grid –Data confidentiality and integrity (commercial context, patient's data,...) [IN PROGRESS] –Fine resource access control [IN PROGRESS]  Deny or grant access to a resource for a user, a group of users, a VO, a role,... –Pseudonymity [NOT STARTED]  Accessing the grid with a pseudonym instead of user real identity According to Ake Edlund, JRA3 manager

R Mollon, C Blanchet - EGEE Security Status – Biomed – Valencia, January 27th, Enabling Grids for E-sciencE INFSO-RI EGEE Security Overview (2) Low-level security functionalities : –Monitoring & Logging [DONE]  Analysis : pre-event and post-event  Prevention : scan, attack and intrusion detection  Identification : responsibilization and non-repudiation –Authentication [DONE]  Trusted Third Party (TTP)  X.509 certificates with a Public Key Infrastructure (PKI) –Authorization [IN PROGRESS]  Virtual Organization (VO) – the Biomed VO for example user group with a common goal who want to share their resources  Delegation with proxy certificates : act on the behalf of someone else  VO Membership Service (VOMS) Management of VOs, roles, permissions,... According to Ake Edlund, JRA3 manager

R Mollon, C Blanchet - EGEE Security Status – Biomed – Valencia, January 27th, Enabling Grids for E-sciencE INFSO-RI EGEE Security Overview (3) –Isolation  At local system level : [IN PROGRESS] Minimize user application consequences Local Credential MAPping Service (LCMAPS)  At network level : [FROZEN] Avoid virus/worm propagation, DDoS attacks,... Dynamic Connectivity Service –Encryption key management  User keys (tied to X.509 certificates) [DONE] manage by users themselves, or by dedicated service (MyProxy)  Data keys : long-term encrypted data storage Single key store [DONE] Techniques “M-of-N” [NONE] According to Ake Edlund, JRA3 manager

R Mollon, C Blanchet - EGEE Security Status – Biomed – Valencia, January 27th, Enabling Grids for E-sciencE INFSO-RI EncFile Benchmarks

R Mollon, C Blanchet - EGEE Security Status – Biomed – Valencia, January 27th, Enabling Grids for E-sciencE INFSO-RI Status of data security Anybody can get the list of all files (all VOs) on a SE –Just need to know the LRC_ENDPOINT « lcg-infosites --vo biomed lrc », from GOOGLE, keywords « LRC egee biomed » local-replica-catalog Anybody can get the list of LFNs of a VO –Just need to know the RMC_ENDPOINT change “edg-local-replica-catalog” by “edg-replica-metadata-catalog” From GOOGLE, keywords: « RMC egee biomed » edg-replica-metadata-catalog /services/edg-local-replica-catalog Some lcg-xx commands do not require nor proxy nor valid certificate. –Anybody can list/change/remove any LFN/alias « How anybody can do what he wants with all files stored on the EGEE grid: reality of data security on the EGEE grid »

R Mollon, C Blanchet - EGEE Security Status – Biomed – Valencia, January 27th, Enabling Grids for E-sciencE INFSO-RI Status of data security (2) Some LCG commands don't require a valid proxy certificate –All commands that manage aliases: anybody can modify any file aliases –All commands that list elements (replica, GUID): anybody can list file entities –Even some core commands managing files ! –Sometimes the '--vo' parameter is taken as truth without any further checks

R Mollon, C Blanchet - EGEE Security Status – Biomed – Valencia, January 27th, Enabling Grids for E-sciencE INFSO-RI Status of data security (3) Tests between 2 Vos: biomed and dteam –One file gridified with dteam VO –Then manipulated with biomed VO –Alias was deleted, and a new one was added with biomed VO (!!) –Odd listing command behaviour  lcg-la, lcg-lg, lcg-lr –2 independent catalogs  LRC = {(GUID, SFN)}  RMC = {(GUID, LFN)}  a GUID can be associated with a VO in the LRC and another in the RMC

R Mollon, C Blanchet - EGEE Security Status – Biomed – Valencia, January 27th, Enabling Grids for E-sciencE INFSO-RI Next meetings Next MWSG : March 7-8 at Cern –Biomed attendees: R. Mollon, C. Blanchet “Authorization” session at next GGF16 in Athens (February 13-17) –Biomed attendees: R. Mollon, C. Blanchet (co-organizer) –Agenda: –Abstract:  “This workshop will consider short-term (now and next two years) Grid Authorization and Policy implementations, requirements and issues. It will investigate what improvements can be made to encourage and facilitate interoperability between Grid operational infrastructures. It will also consider lessons learned from today's implementations for the Grid security standards activities in GGF for the longer-term future. The workshop will highlight the Life Science perspective with requirements from the biomed VO in EGEE and in the overall biomedical community. »
