2003/Sept - Update on EDG Security (VOMS) - Ákos Frohner - n° 9 Registration user user cert (long life ) VO-VOMS CA low frequency high frequency registration newconfirmedaccepteddone VO membership request (user) address confirmation (user) allow create to the requestor: address confirmation to the administrator: new request notification denied deny to the requestor: request is accepted/denied (VO admin) web

2003/Sept - Update on EDG Security (VOMS) - Ákos Frohner - n° 10 Multi-VO registration VO-VOMS user user cert (long life ) VO-VOMS CA low frequency high frequency registration VO administration operations u create/delete (sub)group/role/capability u add/remove member of g/r/c u get/set ACLs for these operations VO registration tasks user requested administrative operation; e.g.: user registration = add member

2003/Sept - Update on EDG Security (VOMS) - Ákos Frohner - n° 11 “Login” user user cert (long life ) VO-VOMS CA low frequency high frequency authz cert (short life) proxy cert (short life) voms-proxy-init edg-voms-proxy-init -voms iteam u /tmp/x509_up (normal proxy location) u backward compatible proxy format

2003/Sept - Update on EDG Security (VOMS) - Ákos Frohner - n° 12 Multi-VO “Login” VO-VOMS user user cert (long life ) VO-VOMS CA low frequency high frequency authz cert (short life) proxy cert (short life) voms-proxy-init voms-proxy-init -voms iteam -voms wp6 u single proxy certificate is generated u each VO provides a separate VOMS credential first one is the default VO u each VOMS credential contains multiple group/role entries first one is the default group

2003/Sept - Update on EDG Security (VOMS) - Ákos Frohner - n° 13 Old-style Service VO-VOMS service VO-VOMS CA low frequency high frequency host cert (long life ) crl update gridmap-file mkgridmap Old-style services still use the gridmap-file for authorization u gridftp u EDG 1.4.x services u EDG 2.x service in compatibility mode no advantage, but everything works as before... GSI

23-Oct-03D.P.Kelsey, LCG Security Update, HEPiX16 Future plans (LCG SEC) We are working on a Risk Analysis document –To help set priorities for the year ahead Many of the agreements to date are for LCG-1 (2003) –Need reviewing for 2004 and beyond Authentication –Must agree the future PMA bodies for CA’s EGEE likely to take over this role for Europe –Online CA services, credential repositories KCA, VSC, MyProxy, … Authorization –VOMS likely to be included in LCG-2 –local AuthZ (LCAS/LCMAPS, US CMS VOX) and VOMS-aware services User Registration and VO Management –Workshop at CERN December 2003 Also reviewing the AuthZ technology
