The version of this that I believe is essential is a statement of the types of actions that are envisioned based on a reputation response. I'm not looking for a spec of how the output /will/ be used, but a description of what it is good for and by whom. That is, in concrete terms, what is the work of the group /for/? Who will use it and how? What can they do with it? I find the current draft text confusing on these points, and I'm also very unclear who is lining up to use the output. Absent a vigorous market pull for using the output of the wording group, the danger will be a nicely-done specification that fills what has euphemistically called a much-needed gap. I suggest some meeting time for resolving this. d/ -- Dave Crocker Brandenburg InternetWorking bbiw.net From msk@cloudmark.com Wed Jul 6 21:46:03 2011 Return-Path: X-Original-To: domainrep@ietfa.amsl.com Delivered-To: domainrep@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 90DD221F8A83 for ; Wed, 6 Jul 2011 21:46:03 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -103.152 X-Spam-Level: X-Spam-Status: No, score=-103.152 tagged_above=-999 required=5 tests=[AWL=-0.553, BAYES_00=-2.599, USER_IN_WHITELIST=-100] Received: from mail.ietf.org ([64.170.98.30]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id 3Aql-QOjvp+Y for ; Wed, 6 Jul 2011 21:46:03 -0700 (PDT) Received: from ht2-outbound.cloudmark.com (ht2-outbound.cloudmark.com [72.5.239.36]) by ietfa.amsl.com (Postfix) with ESMTP id EFC8521F8801 for ; Wed, 6 Jul 2011 21:46:02 -0700 (PDT) Received: from EXCH-C2.corp.cloudmark.com ([172.22.1.74]) by spite.corp.cloudmark.com ([172.22.10.72]) with mapi; Wed, 6 Jul 2011 21:46:02 -0700 From: "Murray S.

Again, sorry for the delay - a 10 day trip to Singapore seems to knock out my todo list..

In terms of what I thought might help in the standard, at least in terms of us being able to move to it:

In the DNS variant, we have a domain+ip whitelist which provides a whole host of reputation based on the 127.x.y.z. response, which perhaps goes beyond the scope of the standard to provide guidelines for how to represent the x.y.z (beyond what already exists for RWL).  However, our query is of the format:

<md5 hash>.<cust key>.<service>.<server>
Where:
     - The md5 hash is basically a hash of the concatenation of domain and IP values.
     - The cust key is a both a customer key and identifier, used to control access to the service
     - The service denotes the particular list they are accessing
     - The server is well, the server.

So this matches the draft with the exception of the customer key, but of course you could loosely regard this as being a fit - you may not want to specify the use of a key, perhaps allow for it being there as an option?

As to the md5 hash - we would be happy to switch to a different hashing scheme - I wonder whether the spec can be extended here, in case other users wanted to provide instead encrypted data (rather than hashed data) for some reason - on the one hand specifying a particular hash algorithm means that client components can be standardised - on the other hand, if the standard is too flexible, you end up describing a mechanism too loose to be called a standard at all.

So all in all, to say that we adhered to the standard at the moment would require us to switch hashing schemes, and maybe denote that the <cust key>.<service> actually denotes a <service> for the particular customer....?

What a negative value means rea= lly depends on with what assertion it is being associated. I suspect if consensus is to allow [-1, 1] as the range, then the declarati= on of a new assertion will need to explain how a consumer is expected to ap= ply a negative value or, indeed, if they are allowed at all for that assert= ion. For example, I suggest that in general we say a value of 1 agrees str= ongly with the assertion being made, 0 disagrees with it, and -1 disagrees = and asserts the opposite. SENDS-HIGH-VOLUME might be one for which negative numbers make sense, where= values tending towards 1 mean "yes, this sender sends a huge amount of mai= l", 0 means "this sender sends an average amount of mail", and -1 means "no= , this sender actually sends very little mail". On the other hand, an assertion of SENDS-VIRUSES is one where I can't imagi= ne what a negative assertion might mean (i.e., what's the opposite?).

Who defines the assertions? How do we avoid overlap and confusion between assertions? For, say, an SMTP or XMPP server I could see assertions like this: - SUPPORTS TLS USING A PKIK CERTIFICATE - HAS A CA-ISSUED CERT - HAS A SELF-SIGNED CERT - HAS AN EXPIRED CERT It's not clear how to usefully interpret the results if all of those assertions are in play. :) It also seems that in some systems people might think they can aggregate scores on particular dimensions into general scores. That might be a challenge if the measurements are overlapping or not commensurate. To feel free to tell me this is already defined in a document I haven't had time to read yet...

For example, one can scale the ESTIMATED-USERS by 7G so as to obtain a probability in the [0, 1] range, but such practice alters the nature of the original statement somewhat. Another example is dates, useful to express qualities such as REGISTERED-ON, FIRST-HAM-EVER-SENT. It may be preferable to have a few homogeneous types, identified by ranges --not necessarily numeric--, and leave any scaling to the "secret sauce" recipes.

Yes, there's some overlapping. It is not clear to what extent WHOIS information is going to be complemented and not rate limited. The existence of an abuse mailbox and, possibly, the number of complaints sent to it may also be interesting.

The dictionary defines reputation as "the estimation in which a person or t= hing is held, especially by the community or the public generally". It thu= s seems to me that your two suggested qualities might be things one uses in= computing a reputation, but are not themselves reputations. You might use a domain registration date as part of the overall data set yo= u use to assert a SUSPECT reputation, for example, where that value tends t= owards 1 as the registration date is more recent.

The only things you should collect about a system are objective facts. In the email realm, it is objectively true that machine 10.1.2.3 tried to send a message to a nonexistent recipient, or that machine 10.2.3.4 send an email that was classified as spam by a human. The subjectivity comes when you combine knowledge of facts to form an opinion about the system. I don't believe your charter gives any guidance about how to do this (and it probably shouldn't.)

How can these statements be reconciled? -- Andrew Sullivan ajs@anvilwalrusden.com From barryleiba.mailing.lists@gmail.com Thu Jul 28 20:20:52 2011 Return-Path: X-Original-To: domainrep@ietfa.amsl.com Delivered-To: domainrep@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 667F321F86DC for ; Thu, 28 Jul 2011 20:20:52 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -103.056 X-Spam-Level: X-Spam-Status: No, score=-103.056 tagged_above=-999 required=5 tests=[AWL=-0.079, BAYES_00=-2.599, FM_FORGED_GMAIL=0.622, RCVD_IN_DNSWL_LOW=-1, USER_IN_WHITELIST=-100] Received: from mail.ietf.org ([64.170.98.30]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id UCpSebcwcul5 for ; Thu, 28 Jul 2011 20:20:51 -0700 (PDT) Received: from mail-yx0-f172.google.com (mail-yx0-f172.google.com [209.85.213.172]) by ietfa.amsl.com (Postfix) with ESMTP id C3D9821F86D7 for ; Thu, 28 Jul 2011 20:20:51 -0700 (PDT) Received: by yxp4 with SMTP id 4so2532356yxp.31 for ; Thu, 28 Jul 2011 20:20:50 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=gamma; h=mime-version:sender:date:x-google-sender-auth:message-id:subject :from:to:content-type; bh=JsB2O0JDbIBk3xgW3q83C/icSMUSxOd42CXAlmWXqa8=; b=V060L/ZimhLZ9EUZ/2VpdyZYHOqYovY2w6Jr7S9Ne2UBi1JeqYLxir5ghmJD0QiHjO IYpp0M0kNKJ8WtTGHwKSwKGNIhSZMSaKZi76+mhcP58YlQrJVE3Dhd0qWsz/9V0ON7SC UpSZJJm29J3BipLHYsQAQ8RJr+oLTjmAKq6Fk= MIME-Version: 1.0 Received: by 10.146.105.16 with SMTP id d16mr514711yac.13.1311909648936; Thu, 28 Jul 2011 20:20:48 -0700 (PDT) Sender: barryleiba.mailing.lists@gmail.com Received: by 10.147.32.15 with HTTP; Thu, 28 Jul 2011 20:20:48 -0700 (PDT) Date: Thu, 28 Jul 2011 23:20:48 -0400 X-Google-Sender-Auth: tR1U44ZoWyGyc382epho_0zru8Y Message-ID: From: Barry Leiba To: "domainrep@ietf.org" Content-Type: text/plain; charset=ISO-8859-1 Subject: [domainrep] Minutes from the BoF posted X-BeenThere: domainrep@ietf.org X-Mailman-Version: 2.1.12 Precedence: list List-Id: Domain Reputation discussion list List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 29 Jul 2011 03:20:52 -0000 I've just posted minutes from the IETF 81 BoF session, here: http://www.ietf.org/proceedings/81/minutes/repute.txt I made these unusually detailed for the discussion part, because I wanted them to capture as much of the discussion as was reasonable. Still, the recorded audio is the best place to go to hear what happened, and that is here, for now: http://www.ietf.org/audio/ietf81/ietf81-2103-20110725-1256-pm.mp3 Start listening two hours and ten minutes or so into the recording. At some point, the Secretariat will be splitting the audio files, so that our session will be in its own file.

X-BeenThere: domainrep@ietf.org X-Mailman-Version: 2.1.12 Precedence: list List-Id: Domain Reputation discussion list List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 29 Jul 2011 22:24:25 -0000 Dear All, At the 81th IETF BoF I've volunteered to contribute to the hopefully soon-to-be WG REPUTE. Hopefully this mailinglist can provide me with some feedback on the braindump below. Is it useful to expand this? My research team has running code, used by a few thousand people related to this use case. At some point we would love to contribute this (provided the WG+charter is ready for this). This email can hopefully combined with others in a "Survey of Proposed Use Cases for REPUTE". Proposed use case: information dissemination We define information dissemination broadly as: "the act of forwarding, relaying, caching and broadcasting packets of data towards others". We use the label "information dissemination" in a very general way deliberately. This enables us to create a common framework for four use case instances, each of which are used by millions of Internet users. Disseminating information requires several type of resources such as storage, networking and computation. Problem outline: this REPUTE use case enables participants to spent their valuable resources only on those people which are most likely not "bad actors". This promotes good behaviour, enhances performance and provides increased social welfare in general. This use case is focussed on collaborative and self-organising systems where the users share resources freely. We target the following four use case instances: 1) open wifi base station - exchanging information between the wireless and wired domain. 2) Packet forwarding - Relaying packets in an Mobile Ad-hoc Network (MANET) 3) Caching proxy - Relaxing information for others in order to enhance performance and privacy on the wired Internet 4) file sharing - pooling storage capacity together in order to build a vast archive of content Commonality between the four instances is that without REPUTE there is no mechanism to make an assessment of the trustworthiness of others. Every participant in the above use case instances MUST use REPUTE to determine if it should honour the request for resource usage. We define the reputation of an identifier or "value" in this use case: the reputation score reflects to which extend this identity has engaged in a cooperative manner in the information dissemination ecosystem. Therefore, only participants with a sufficient REPUTE value will see their information dissemination requests fulfilled. Leechers get degraded performance, get delayed before service or will not obtain any service.
