Dear all, The OGF Security Area would like to draw your attention to an initiative addressing topics around the concept of Levels of Assurance. We know or expect that at least quite a few of you are interested in this topic, and thus are likely to either participate and have an opinion on this... An initial description of the activity and possible directions are described below. Please note that this will be a topical activity BoF, and is not aimed to be a charter BoF or to necessarily create a new group. If there is sufficient momentum to address this topic (also) in the OGF context, we can subsequently discuss the organisational embedding in an existing or new group. So, if you are interested, please participate via the security area mailing list or the gforge Wiki and forum, whose URLs are listed below. A BoF session to discuss this activity will be organised during OGF19 (to be held in North Carolina on January 29 - February 2, 2007). You are very warmly invited to attend this event, which will be full of new activities in the security area. Best regards, Blair Dillaway and David Groep, (OGF Security ADs) Topical BoF on Levels of Assurance (LoAs) ----------------------------------------- Ideas around "Levels of Assurance" have been receiving more and more attention, with the advance of federations and Authentication and Authorization infrastructures. "LoA is defined as the strength of authentication required for a service provider to be assured that a resource access is only granted to users whose identities have been verified. It reflects the degree of confidence in an authentication process used to establish the identity of an entity (an individual or a software component) to whom the credential was issued, and the degree of confidence that the entity using the credential is indeed the entity that the credential was issued to." Ning Zhang of Manchester University has taken the initiative to bring up the discussion on this activity in the OGF context. Examples of questions that this activity could address are: - What are the existing definitions of LoA suited to Grid or VO environment? - How to apply LoA to safeguard Grid services/resources? - Are some onerous registration requirements or special condition stipulations due to perceived inadequacies in the strength of authentication? - Are there any limitations in terms of user accessibility, scalability and interoperability? The activity can include discussion on how operational procedures affect LoA, how the various parameters and factors influence the overall LoA value in grid/VO environments, and come up with recommendations on how these factors can be taken into account. The purpose here is to consult, and to seek comments and feedbacks from, the communities concerned (including service providers, from e-Science, e-Business and e-Gov) on their views on the definition and applications of LoA in achieving fine-grained access control. Everyone interested in such an activity is extremely welcome to attend this activity BoF session. If there is sufficient interest within OGF, the BoF can also discuss how the activity is best embedded in the OGF organisation; it is not necessarily the aim of this BoF to result in a new research or working group.
