  1. Security Middleware Andrew McNab High Energy Physics University of Manchester Security Middleware, GridPP8, 23 Sept 2003

  2. Overview • Security in EDG/GridPP-1 • Currently deployed (EDG 2.0) • Being integrated (EDG 2.1) • GridPP-2 requirements • GridPP-2 proposal • GGF Involvement • Research Areas Security Middleware, GridPP8, 23 Sept 2003

  3. Security in EDG / GridPP-1 • When proposals were written, Security mostly just seen as Authentication (CAs etc) • From Globus, we inherited the static, manually edited /etc/grid-security/grid-mapfile • Better Authorization mechanisms were needed to make the Testbed actually work. • In EDG, security effort split between WP7 (networking) and WP6 (“getting things to work”), but also components inside WP1-5. • In GridPP, security middleware effort from WP6. Security Middleware, GridPP8, 23 Sept 2003

  4. Currently deployed middleware • Pool accounts (from GridPP) • an short term measure that’s become long term and ubiquitous. • XML Grid Access Control Lists (from GridPP) • used by Storage Element, but grew out of GridPP GridSite work. • Other components: • INFN’s VO-LDAP server (GridSite implementation of this used for GridPP+BaBar) • WP2 Java Security packages. • Specific security pieces inside each WP. Security Middleware, GridPP8, 23 Sept 2003

  5. Middleware being integrated • INFN-WP6/WP2 Virtual Organisation Membership Service is major component • (GACL support for VOMS attribute certs already present in EDG 1.x/2.0) • GACL support in WP4 LCAS/EDG Gatekeeper • so can write XML site access policies, rather than use grid-mapfile • VOMS, and new GSI + X509v3 support added to GridSite and mod_ssl-gridsite • HTTPS servers controlled by VOMS+GACL • WP1 Logging and Bookkeeping using GACL Security Middleware, GridPP8, 23 Sept 2003

  6. GridPP2 Security Middleware • GridPP2 focuses on practical requirements of production systems (LCG + EGEE) • Many gaps in functionality of security systems • eg accounting / usage control • Based on WP6 + WP8 + LCG requirements documents, identified 8 tasks • extend GridPP 1 work to address urgent gaps • Research rather than implementation areas left out of this • aim to get funding for these elsewhere Security Middleware, GridPP8, 23 Sept 2003

  7. GridPP2 Proposal • GridPP2 Security Middleware Proposal • Java and C++ APIs for GACL library • Add Usage Control (quotas etc) handling • Improve/generalise GridSite user interface • VO access and usage management service(s) • Support for other systems: CAS, VOM etc • Auditing/Intrusion Detection • Porting to other Unix/Windows flavours • This was estimated at 4 FTE, but with 2.5 FTE in GridPP2 proposal as submitted. Security Middleware, GridPP8, 23 Sept 2003

  8. GGF Involvement • Participating / influencing / following GGF standards clearly helps our work: • less effort supporting multiple protocols • our implementation attractive to more projects • I’m co-chair of Authz WG and now the OGSA-Authz WG • aim to standardise policy language (cf GACL) • assertion protocol (eg SAML, LCAS callout) • attribute formats (eg VOMS) • Also contacts with Accounting GGF groups, via Manchester Computing / eSNW. Security Middleware, GridPP8, 23 Sept 2003

  9. Research areas • PPARC-funded e-Science Studentship • Starting now, on Authorization/Accounting. • Aim to get involved in GGF WGs’ protocols and models work, and apply to HEP contexts. • This may feed into GridPP2 implementations. • Other research proposals underway: • How to support ad-hoc, short term VOs • Using SlashGrid to create on-demand security contexts and sandboxes for native binaries • Medical Applications, including extensions of PPARC/MRC project at Manchester Security Middleware, GridPP8, 23 Sept 2003

  10. Summary • GridPP has made significant security middleware contributions to EDG • More will be deployed when EDG 2.1 released • For GridPP-2, we identified key practical requirements • wait to see how many can be addressed • Direct involvement in GGF standards process • Other funding obtained (studentship) or being sought (EU and MRC/DoH) for further research rather than implementation Security Middleware, GridPP8, 23 Sept 2003
