Nicholas, Concerning security use cases for the 'European Roadmap on Grid and Cloud Standards for e-Science and beyond' : The link I provided is the EDGI Use Case 'Enforce Security of a Production Service Grid' at http://forge.gridforum.org/sf/go/doc16010 This security use case has been incorporated (alas without the diagram) as chapter 5 of the OGF PGI 'Use Case Collection' officially published by OGF with id GFD.180 at http://www.ogf.org/documents/GFD.180.pdf Besides, I consider that the main sources of information about security in DCIs are : - Symposium on Authentication Technologies (including a Roundtable on Cloud and Grid Security Standards) held at Texas Tech University on 4-7 October 2010 http://indico.rnp.br/conferenceDisplay.py?confId=85 Many thanks to Alan SILL who provided this information to the SIENA REB in his mail dated 05 October 2010. - EGI SPG (Security Policy Group) https://wiki.egi.eu/wiki/SPG - GLUE Specification v. 2.0 http://www.ogf.org/documents/GFD.147.pdf In particular its figure 1 at page 7 clearly shows the separation between the concepts of 'UserDomain' and 'AdminDomain' : 'Access Policies' permit users (members of different 'UserDomains') to make usage of 'Services' managed by separate 'AdminDomains'. - EMI Security Architecture https://twiki.cern.ch/twiki/pub/EMI/EmiJra1T4Security/SecArch_v0.1.pdf I am available for further information.

Dear Etienne,
Many thanks for your contributions to the REB conference call on Wednesday. During the call you made reference to security use cases but I was unable to copy down the link you sent. Could you send me the link please so that I can add it to the meeting minutes.
Many thanks
Nick
