Re: [secdir] [OAUTH-WG] ** OAuth Tutorial & OAuth Security Session **

["Richard L. Barnes" <[e-mail]>]

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.

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.
