Security topics from OSG Consortium meeting agenda, invitation to participate in OGSA-AuthZ standards process
by Alan Sill 21 Jan '06

21 Jan '06

Hi Ruth, I cannot attend the OSG meeting but note with pleasure the progress you have made on OSG security topics, including appointing a facility security officer and identifying issues of interest. As an OSG participant, I am happy to see these issues addressed. I am also continuing to stay active in identifying issues for my own project (TIGRE) and remain active in relevant standards bosy work. At the last OGSA-AuthZ working group meeting (being organized in consultation and cooperation with the OSGA-WG group for organizational guidance), there was agreement with the point that I raised and that others echoed that a stronger effort should be made to obtain involvement in the activities of this group from a variety of real-world grid projects, such as OSG and others (a long list was given) for practical reasons in the standards development process. I look forward to engaging with OSG representatives as this process continues, but for the moment, please consider this to be an invitation to supply the names of a contact or contacts from OSG to represent it in AuthZ discussions in the context of OGSA-AuthZ. I extend this invitation on behalf of and as a member of the OGSA-AuthZ group, which is in the process of considering a recharter to extend its original design goals. Participation from OSG along with other major grid projects would definitely be welcome, from the sentiment expressed at our most recent meeting in Sunnyvale.

REFEDS
by Alan Sill 20 Jan '06

20 Jan '06

Hi David et al., In response to your question, with no endorsement or criticism implied, see http://www.terena.nl/tech/refeds/ for information regarding the REFEDS initiative. I'm just learning about it myself. (It does include a reference however to eduroam, as we discussed.) I believe there will be further discussion of this topic among others at the next EUGrid PMA meeting (see http://eugridpma.org ). As I mentioned, I believe we need to get buy-in into the AuthZ recharter and goals process as quickly as possible, including formal representation, from such projects as Open Science Grid, the LHC Computing Grid and/or EGEE, PRAGMA, NAREGI, and other communities with an active interest in the authorization area, such as Internet2 and EDUCAUSE. I do not speak for such projects but would like to see them included... and I am excited about this prospect.

Comments on ogsi authz requirement document
by Von Welch 15 Jan '06

15 Jan '06

It was recently pointed out to me that we have a comment on the OGSI Authorization Requirements document in GridForge (the fact that the WG should be notified of these things has been passed along to GGF). The comment is at: https://forge.gridforum.org/forum/forum.php?thread_id=972&forum_id=560 I include my response below as a convenience to the WG. Further response should be done via GridForge. Von -- > By: Guruprasad B Nagaraja > Subject: OGSI Authorization Requirements.pdf[ Reply ] > Date: 2005-10-13 Apologies for the long delay in responding. These comments are appreciated, but I only recently became aware of their existence.

I agree that authorization services should have some notion of policy in regards to whom can request policy decisions. How about added a new bullet to this section (section 5): * Access Control to Authorization Decisions: For reasons of security and privacy, authorization services should be capable of enforcing access control on who can request authorization decisions. In the simplest incarnation, authorization services should be configurable so that they only answer queries from a set of trusted target resources. More complex implementations could allow for finer- grained policy based on the initiator and request. Some implementations may even want to require proof of that an initiator requested an action in order to authorize it. > > Please note that these comments have been made with the intension > of pariticipating > in such discussions and to learn more.

Use of SAML for OGSI Authorization back from public comment
by Olle Mulmo 13 Jan '06

13 Jan '06

Hi all, The document "Use of SAML for OGSI Authorization" came back from the public comment period with zero comments. I'm not very keen to start another period just to follow process but rather I suggest that I exercise my power as AD and close the sack on this document anyhow. Thoughts at this point? /Olle
