(With apologies for bringing up a tangential matter...)
Talking about the OAuth model, I still see here "Client" instead of
"Consumer." I thought there was an agreement on the terminology
change. I have no specific preference for either term, but I think it
is essential that our terminology be consistent, especially now that
other SDOs are considering adopting OAuth.
This is not necessarily a question for Richard, but could someone set me
straight: Is it "Client" or "Consumer"?
With thanks,
Igor

Of course not every scenario calls for all of the security knobs to be
turned to 11. Think of things instead in terms of syllogisms: "IF you
want X guarantee, THEN you MUST do A, B, C."
Then you can also read the same things backwards in a given deployment
scenario: "Given that I can't do B, I can't get assurances X, Y, but I
can get Z (if I do D, F as well)".
I promise to produce something more concrete soon :) In the meantime,
this text illustrates what I mean pretty well:

not be what somebody else wants) can vary depending on scenario and

I would say that the security considerations should be based on a
model of OAuth. Start with a model of the protocol and the
guarantees you want, then explain how to use security mechanisms to
achieve those guarantees.
I promised Hannes today to do a review of the current document (which
I admit I haven't read) and start on some security considerations
from that perspective. So expect that in the next few weeks.

We think the security considerations should be based on a threat

We therefore aim to produce a separate security document
(informational I-D/RFC) covering threat model as well as security
design and considerations. The security considerations section of
the core spec can then be distilled from this document.

I was looking for less of an analysis and more of considerations (of
the current flows and actors), I'm not sure how to adapt what you
have done to actually fit in the current specification, was your
thought that you would produce a separate security analysis document?

Hi all,
Mark McGloin and me have been working on OAuth 2.0 security
considerations for a couple of weeks now. Since we both cannot
attend the IETF-79 meetings, we would like to provide the WG with
information regarding the current status of our work. I therefore
uploaded a_preliminary_ version of our working document to the WG's
wiki at
http://trac.tools.ietf.org/wg/oauth/trac/attachment/wiki/SecurityConsiderations/oauth20_seccons_20101107.pdf.
The focus of this version was on consolidating previous work as well
as results of mailing list discussions and start working towards a
rigorous threat model.
Please give us feedback.
regards,
Torsten.

Hi all,
please consider attending the following two meetings!
** OAuth Security Session **
* Date: Monday, 13:00-15:00
* Location: IAB breakout room (Jade 2)
* Contact: Hannes Tschofenig hannes.tschofe...@gmx.net The
security
consideration section of OAuth 2.0 (draft -10) is still empty.
Hence, we would like to put some time aside to discuss what
security threats, requirements, and countermeasures need to be
described. We will use the Monday, November 8, 1300-1500 slot to
have a discussion session.
As a starting point I suggest to look at the following documents:
*
http://trac.tools.ietf.org/wg/oauth/trac/wiki/SecurityConsiderations
* http://trac.tools.ietf.org/wg/oauth/trac/wiki/SignaturesWhy
*
http://tools.ietf.org/id/draft-tschofenig-oauth-signature-thoughts-00.
txt
Note: If you are unfamiliar with OAuth then the OAuth tutorial
session might be more suitable for you!
** OAuth Tutorial **
* Date: Wednesday, 19:30 (after the plenary)
* Location: IAB breakout room (Jade 2)
* Contact: Hannes Tschofenig hannes.tschofe...@gmx.net OAuth
allows
a user to grant a third-party Web site or application access to their
resources, without necessarily revealing their credentials, or even
their identity. The OAuth working group, see
http://datatracker.ietf.org/wg/oauth/charter/, is currently trying to
finalize their main specification, namely OAuth v2:
http://datatracker.ietf.org/doc/draft-ietf-oauth-v2/
Based on the positive response at the last IETF meeting (in
Maastricht) we decided to hold another OAuth tutorial, namely on
*Wednesday, starting at 19:30 (after the IETF Operations and
Administration Plenary) till about 21:00. (Note: I had to switch the
day because of the social event!)
It is helpful to read through the documents available int he
working group but not required.
