Teleconference minutes - 25 September 2006
by Andreas Savva 28 Sep '06

28 Sep '06

Attached. https://forge.gridforum.org/sf/go/doc13903?nav=1 -- Andreas Savva Fujitsu Laboratories Ltd OGSA Teleconference - 25 September 2006 ======================================= * Participants Mike Behrens (R2AD, LLC) Mukund Buddhikot (SUN) Chris Jordan (SDSC) Hiro Kishimoto (Fujitsu) Tom Maguire (EMC) Mark Morgan (UVa) Andreas Savva (Fujitsu) Alan Sill (TTU) Paul Strong (eBay) Jem Treadwell (HP) Minutes: Andreas Savva * Summary of new Actions AI-0925a: Hiro to setup wiki page with names of people who have expressed interest in the security team AI-092625b: Jem to pull definitions together and produce a new merged first draft. - Send a mail to the ogsa list about this work - Set Oct. 9 as the target for the first Glossary draft AI-0925c: Hiro to ask Alan Clark to ask EGA TC member who want to contribute to join the OGSA list and this convergence work. - Members may have changed but organizations have not AI-0925d: Paul Strong to send EGA Glossary MS-Word file to Jem Treadwell AI-0925e: Hiro to talk with Andrew Grimshaw and Mark Morgan and bring back a concrete proposal for the HPC Profile use case as a convergence candidate. AI-0925f: Hiro to talk with Ellen Stokes and add more items in DMTF register in the context of this convergence work AI-0925g: Tom will send a note to the list (to: Ellen S and Fred M) on why the current separation of service/info model may not be quite right. * Minutes approval ** September 21 minutes approved with no changes ** F2F minutes for September 15 (two parts) approved with minor changes: - Fix Michael Behrens affiliation - Correct AI number overlap * AI review [Only items with updates/comments are listed below] - AI-0921b: Pending. (Really a sub-item of AI-0921c) - AI-0921c: Pending. New Security ADs not selected yet. - AI-0921e: Closed. Alan has sent information to the list - AI-0921f: Closed. Already discussed on the Interop call. - AI-0921g: Closed. - AI-0921i: Close once the agenda is fixed - AI-0914b: Closed. There was a call last week. - AI-0925a: Hiro to setup wiki page with names of people who have expressed interest in the security team - AI-0912a: Closed. Today's discussion. * EGA Reference Model Discussion ** Glossary - Jem gave an overview of his glossary presentation from GGF18; number of terms and overlaps (or non-overlap) - Explanatory (EGA) vs more formal/committee style (OGSA) definitions - Should also look for less obvious overlaps, beyond just same/different terms - Should probably define some new ones (e.g., Enterprise) - Possible editors for this work: Jem Treadwell & Paul Strong - Glossary convergence should be done in the context of other convergence work (i.e., Reference Model and OGSA) - The EGA reference model structure and verbosity of the Glossary is driven by the expected consumers of the documents. One reason that more text was pushed in the Glossary was to avoid excess overlap with definitions. - Might need to have taxonomony/ontology discussion to sort out things - Is a single Glossary possible? - Probably no problem doing it. - There is no way but to have a single Glossary - The OGSA Glossary is specific to the OGSA Architecture document---for scoping reasons. (In other words, it is not a general Grid or GGF Glossary.) - Occasionally there are 'battles' over common definitions of terms. Having an OGSA definition should not stop others from having their own definitions of terms. - Definitions of terms perceived to fall in this category are often prefixed with "In OGSA, " in the Glossary to make the context clear. - How to proceed? Wait for broader work to start? - No need to wait. Could start small, using email and then use the occasional call/F2F meeting to resolve remaining problems - In terms of process the OGSA list should be used AI-092625b: Jem to pull definitions together and produce a new merged first draft. - Send a mail to the ogsa list about this work - Set Oct. 9 as the target for the first Glossary draft - Mike Behrens also volunteered to help out on the Glossary - Is everyone from EGA on the OGSA list? Maybe. - Are the EGA lists still active? The EGA alias does work and people have been invited to join AI-0925c: Hiro to ask Alan Clark to ask EGA TC member who want to contribute to join the OGSA list and this convergence work. - Members may have changed but organizations have not - Is the EGA Glossary available as an MS-Word file? It would simplify the work for the first draft. (The pdf version is otherwise sufficient.) AI-0925d: Paul Strong to send EGA Glossary MS-Word file to Jem Treadwell - From a more general perspective, it would be nice to have the EGA documents available on the OGF site. - This was assigned by OGF to the OGF Editor (Greg Newby). He is now reading the EGA documents. ** Reference Model and OGSA convergence - At GGF18 the proposal was to consider OGSA as a rendering of the EGA reference model. Agreed that this seems a good starting point. It should be tested by picking a candidate topic and see if it is really the case. - Hiro proposed the OGSA HPC Profile as a test case (a concrete use case) - The HPC Profile is more detailed when compared to the style of the use cases in the EGA Reference Model. Therefore it would help flesh out what is needed in the context of OGSA. Doing UML would be good. - It was noted that EGA graphs (DAGS) are specific to instantiation - Tentative agreement on the HPC Profile proposal but need more information before making a decision. AI-0925e: Hiro to talk with Andrew Grimshaw and Mark Morgan and bring back a concrete proposal for the HPC Profile use case as a convergence candidate. - What are the deliverables? - If the use case approach works then the refinement could be put in the next version of Reference Model. - Should this work be in the same WG? Should a new OGF Reference Model WG be formed? - Forming a new WG is a possibility, especially since the reference model work is at a different level from other OGSA work - Initially this work can start in an OGSA design team. It could be spun out later when the scope is clearer. A decision could be made by the end of the year. - Does this mean that the result is a converged model? - Yes, the result would be a reference model that also covers the HPC space, in addition to the enterprise space. - Can we expect more use cases from EGR-RG? - Maybe but their use cases are more abstract - Paul Strong may bring more use cases - Part 2 of the Reference Model document includes use cases. Should these be in a separate document? Or should the work be done in a different WG? - Doing the use case work in the same WG is ok - Typically the use case document would be a separate document - Another open issue is how does the Information Model work (in context of DMTF) comes together with the EGA reference model (dags). - A possible viewpoint is that the EGA Reference Model is the overarching model: - With specific/concrete stuff mapping to CIM - But some more abstract stuff do not map to CIM easily - There is some more abstract work in the SMIS space and this will end up at some point in DMTF schema - So the DMTF might be an eventual consumer for some of this work AI-0925f: Hiro to talk with Ellen Stokes and add more items in DMTF register in the context of this convergence work AI-0925g: Tom will send a note to the list (to: Ellen S and Fred M) on why the current separation of service/info model may not be quite right.

25 Sep '06

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I had some issues with Word destroying my latest draft of the document, but I've uploaded a less-recent version with some schedule and status updates. It is incomplete, but I'm mostly interested at this point in feedback on how I'm currently handling documents which have been released as GFDs and which don't have definite plans for future versions yet. So if you'd like to discuss the roadmap document in todays call, please take a look specifically at the OGSA Architecture and glossary sections, along with other documents in a similar state, such as JSDL 1.0. Not all documents have updated status in this version, but I left track changes on so you can see what I have updated in this version.

The recently released WS-Metadata Exchange specification shows (examples of) how this annotation can be done. The approach should be applicable here. - Initially this issue was specifically about adding porttype information but WS-MetadataExchange shows how any kind of information may be embedded. - (Dave S) There is non-normative text in the WS-Addressing Core specification (sec. 2.2, under endpoint Metadata extensibility) that refers to examples on how to include wsldLocation information. This is sufficient and there is no need to use the WS-MetadataExchange spec. - There were questions about the status of the WS-MetadataExchange specification. It is not in a standards body yet.

Closed. * GGF18 and F2F meeting discussion - Event went quite smoothly. - A good set of specs are coming to completion; felt like many things are finally getting done. There are lots of implementations (of BES, etc) including from MS. The interoperability activity was started and looking forward to the results. - There was no chance to cover some issues, like the relationship between OGSA Security work and other (OGF) security work. But this is on the agenda of this call. ** Minutes approval - Information Model Minutes (two) (Fred M)--approved with no changes - EGA Reference Model (one) (Andreas)--approved with no changes - EMS Scenarios (one) (Hiro)--approved with no changes - F2F minutes, Thursday (Michel D)--approved with no changes - F2F minutes, Friday 1. (Michel D)--approved with no changes 2. (Andreas)--approval postponed for next week because there was insufficient time to review them before the call. - All the material is believed to have been uploaded. Let the chairs/secretary know if anything is missing. * Security Profile review postponed * OGSA security Led by Dave Snelling. OGSA security work has produced two security profiles (Core and Secure Channel). Both are close to publication. One question is what should be the next work items of the design team. The HPC Profile interoperability work is probably facing an immediate problem since there is no profiled way to pass the required identity credentials for job submission. There is a gap in authentication---the OGSA security profiles only go as far as defining a secure channel. Therefore a short-term work proposal is to identify what the next minimal use cases are and to produce profiles to address them. The result could be a profile on how to do authentication. (There is no OGSA-AuthN group.) From a broader perspective there are a number of security groups (FI-RG, OGSA-AuthZ-WG, TC-RG) and a lot of good work has been done already. But it is not clear what the connections are. Alan Sill said that the CAOPS-WG has also been very active. CAOPS has been somewhat incorrectly categorized as operations; it does in fact also do design work and should have a connection to OGSA. (There are some worries that the practice of academic users may be getting decoupled from broader OGSA work.) The group was spawned by the Grid PMAs--which also formed IGTF. IGTF's purpose is authentication in a federated infrastructure. The CAOPS-WG was created to cover specific needs of educational organizations--bridging between organizations. It is not clear how this work links to the commercial world. (Commercial CAs are in the business of issuing server certs; EDUs for identity.) A main driver has been the federal government---driving use by requiring (path validation) by legislative means. - Peter Alterman @NIH Federal Bridge: runs commercial solution Is a lot of the work still around plain x.509 certificates? No, VOMS uses extended attribute certificates. - A higher level view is that x.509 certificates with SAML assertions seem to satisfy most requirements - It is not clear how industry views attribute extensions One issue is to identify what is needed for web (grid) services. A lot of existing (or pursued) approaches (CAS, Kerberos, etc) in other bodies are done without reference to specific Web services requirements. A number of different approaches for authentication were mentioned: - vanila x.509 - x.509 extensions - EPI based identity (UVA) - 'pure' SAML (identity is just another assertion) What is the current OGSA level? - Use of x509 certificates to establish a secure channel between client/server. There is mutual authentication between client and server. If a single CA is used for tests is it enough? And could it be extended later to support bridging? - The weak point is atribute extension and path validation; otherwise it works for the small case. - For the (small) base case it is sufficient to have copies of the base root certificates and be able to check whole chain (including checking all additions; so it is simpler not to allow additions). This setup is enough for basic interop but it is really functionality that has been available for the past 10 years. - Bridging is actually a lot more complicated. Another possibility for future work is to define a standardized path validation i/f that hides the operations behind, which are quite complex. - But this may be longer term work. It goes beyond current interoperability work. - Alan mentioned a number of people that might be worth including in such a discussion. - Frank proposed doing a BoF for such a path validation i/f and also proposed Alan Sill as a good person to lead it. For the Interoperability workshop one could arrange for an IGTF accredited CA; install it on both sides. (It has the advantage of also plugging in the federal infrastructure.) - It is not clear if such a setup would be acceptable to all participants. - It is not clear whether the use of the OGSA security profiles is going to be acceptable either. - Interoperability calls are being planned and this issue should be taken up there. - Richard Ciapala (richci 'at' microsoft.com) is organizing the interoperability work/calls. AI-0921b: Security members to discuss the BoF proposal(s) further - For example, one outcome could be some standards activity to mirror CAOPS activities and tie-in to OGSA AI-0921c: Dave S (as Standards VP) to talk to the next Security AD (when one is selected) about the Security Area task list. AI-0921d: Dave S to collect additional material in order to identify security issues better. - (AI-0921e is an issue instance) AI-0921e: Alan S to provide material on the issues relating to path validation. AI-0921f: Dave S to ask Richard C to put the security topic on the agenda of the first Interoperability call and to also ask that the teleconference announcements be sent to the OGSA list AI-0921g: Hiro to add Alan Sill to the OGSA-WG list AI-0921h: Hiro to allocate a slot to review security work progress at a future call. Perhaps Oct 5. AI-0921i: Dave S to provide an agenda for the next security call. - Draft agenda items: - What needs to be done to achieve simple interop generally and to bootstrap more - Profile to get authentication information from a secure channel for authentication - Profile for other methods to get authentication informatin for authorization

Links for material on path validation and on the IGTF, etc.
by Alan Sill 22 Sep '06

22 Sep '06

Per action items from meeting of 21 Sep. 2006: A link for information on the International Grid Trust Federation (IGTF) and its activities with respect to the large-scale grids in science and academics is below: http://www.gridpma.org/ Information in general on path validation is available at http://tools.ietf.org/html/rfc3379 I will look for and try to supplement the above with information specific to path validation and related issues for the use of Bridge CAs and similar structures in grids as soon as possible. Note that The Americas Grid PMA (TAG PMA) has formed a working group on the above issue including members from the other PMAs, and that is currently in process. There is also extensive activity, especially in the Internet2, Educause and related sectors with respect to the use of Shibboleth with grids, including related PKI and X.509-embedding issues, see http://grid.ncsa.uiuc.edu/events/ggf18-shib-bof/ Best, Alan Alan Sill TIGRE Senior Scientist High Performance Computing Center TTU ==================================================================== : Alan Sill, Texas Tech University Office: Admin 233, MS 4-1167 : : e-mail: Alan.Sill(a)ttu.edu ph. 806-742-4350 fax 806-742-4358 : ====================================================================
