<tlr> RESOLVED: approved

tlr: go through action items

tlr: bunch of them closed if nothing said...

tlr: hal wanted 53,56 & 62 to be closed

<tlr> Hal asked by ail to close ACTION-56, that was done last time

tlr: 56 was done

<tlr> ACTION-53, ACTION-62 closed

<tlr> ACTION-65 closed

<Tyler> Are we speaking in hexadecimal this morning?

tlr: reminder about 0xf2f

<tlr> http://www.w3.org/2006/WSC/wiki/MeetingTaxisAndDinners

tlr:reminder that usable security workshop CFP position papers are due by jan 12

<tlr> http://lists.w3.org/Archives/Public/public-wsc-wg/2007Jan/0022

<tlr> http://www.w3.org/2006/WSC/wiki/NoteUseCases

<tlr> http://www.w3.org/2006/WSC/wiki/PadlockIconMisuse

tlr: summarises problem (see the wiki)

<tlr> http://www.w3.org/2006/WSC/wiki/NoteIndex

tlr: proposes moving to elsewhere in Note since its less a use-case than something else
... maybe move to "problems with current stuff" section

<tlr> silence; agreement

Tyler: should I re-draft this as a use-case?

tlr: suggests leaving in descriptive mode

SharedUserSystem

<tlr> http://www.w3.org/2006/WSC/wiki/SharedUserSystem

tlr: similar to last one
... once again, move to "stuff we deal with" section
... suggests tlr
... asks hal to suggest where to put this

hal: now thinking this is a bit far-out, happy to rework
... if that's what's wanted

<Tyler> +1 on calling shared computers out of scope

tlr: maybe morph to use-case & say that its out of scope or
... else extend out-of-scope section

<scribe> ACTION: hal to rework shared system use-case [recorded in http://www.w3.org/2007/01/09-wsc-minutes.html#action01]

<trackbot> Created ACTION-66 - Rework shared system use-case [on Hal Lockhart - due 2007-01-16].

MultipleCertificateIdentity

Tyler: describes naming problem (e.g. re-directing etc)
... can guess, but nice if could standardise this go get
... rid of heursitc

<tlr> http://www.w3.org/2006/WSC/wiki/MultipleCertificateIdentity

stephenF: bit worried about that

Tyler: explains...talking about matching on DNs as not good enough
... take root etc. into account and maybe that works

hal: practical difficulties big, CAs do different things
... might only get 30% solution, not 80%

Tyler: got 80% already!

PHB: worried also, not sure about ...
... naming vs. merges/splits etc.
... payflow? used to be vrsn now ebay

Tyler: not that level, has bank a/c with name1 for login server
... then 50 servers for transactions each with own DNS name
... but otherwise DNs are the same
... his widget spots that

PHB: not sure thats useful, his bank has no web server
... all outsurced (hopefully not to vrsn:-)
... distinction between trustworthy or not
... prefres EVS certs as a basis for ok'ing linkage
... between differnt PKI based credentials

tlr: hearing debate, so in-scope, but maybe we'll hit a wall
... later

Tyler: maybe I can demo

<tlr> ACTION: tyler to refine MultipleCertificateIdentity use case [recorded in http://www.w3.org/2007/01/09-wsc-minutes.html#action02]

<trackbot> Created ACTION-67 - Refine MultipleCertificateIdentity use case [on Tyler Close - due 2007-01-16].

tlr: probably re-visit @ f2f

SelfSignedCertificates

tlr: recent note

<tlr> http://lists.w3.org/Archives/Public/public-wsc-wg/2007Jan/0077.html

<Tyler> Stephen uses a self-signed cert for a small web site with about 10 users

<Tyler> Stephen would like some way of accurately presenting the security of this scenario

Tyler: also had device use-case (furnance)
... furnace/DSL modem etc small device with https:// on the appliance
... is a good thing, but self-signed for cost and...
... not knowing name in advance

tlr: says in-scope so to be looked at later

<tlr> ACTION: tyler to formalize furnace self-signed use case [recorded in http://www.w3.org/2007/01/09-wsc-minutes.html#action03]

<trackbot> Created ACTION-68 - Formalize furnace self-signed use case [on Tyler Close - due 2007-01-16].

tlr: suggests keeping these use-cases separate

Stuart: asking whether users will verify self-signed or whether
... users don't care about identity

tlr: says most interest is that its the same as last time and
... so different from last time

stuart: says this is like ssh leap of faith

stephenF: yes it is

PHB: case to be made for encrypting by default
... doesn't want to require authentication before
... allowing crypto
... prefers using crappy certs rather than nothing

tlr: is that a new use-case?

PHB: no new use case for now

PossibleMalwareInstallation

tlr: another fresh use-case

http://lists.w3.org/Archives/Public/public-wsc-wg/2007Jan/0076.html

tlr: describes use-case
... suggests privileges/sandbox aspects out of scope.
... but where browser suggests to user an action that

...might violate TCB then that may be in-scope

hal: thorny issue maybe, recent debates about
... plug-ins continue even after we agree what they
... do
... so what is malware?

tlr: agree there's philosophy here

<tlr> ... trying to frame malware as "it might subvert computing base" ...

tlr: want to keep good/bad out of discussion
... user has to allow/disallow actions that change TCB
... browser knows that its changing TCB
... should that action/question from browser be in-scope
... or not

Tyler: are we talking about standardising some GUI so that
... browser will present something to user in this case?

tlr: trying to cover what interactions we deal with later, this is one

Rob: important scenario for users
... aveage users strugggle about what to allow/not
... important for us to tackle

hal: can anyone make that distinction?
... even up to code inspection

Rob: in black-box, maybe there's an engine browser can load (e.g. anti-virus)

hal: anti-phising toolbar and spyware externally visible
... behaviour indistinguishable

tlr: what kind of informaiton is out there and how can it be
... presented usably
... hal's question is a level too deep

hal: willing to go along to see what happens

stephenF: +1 to hal's ok

<tlr> PROPOSED: keep this use case in, as an interaction that we'll deal with

Tyler: easy to notice that an mp3 doesn't affect tcb, whereas
... another one does

tlr: that's what I was thinking about
... proposes keeing in scope

<beltzner> I'm willing to discuss it more, but this sounds like it overlaps if what you're saying is: "help users understand where software is coming from?" but that seems to get into software signing

silence; agreement or snoozing

<tlr> silence

<beltzner> can we add "make hotel internet not suck" to our InScope list?

UserNotions

http://lists.w3.org/Archives/Public/public-wsc-wg/2007Jan/0067.html

but defer to later

http://www.w3.org/2006/WSC/wiki/NoteUseCases

Debugging

tlr: this is on mez, suggest deferring

UserExpectation

http://lists.w3.org/Archives/Public/public-wsc-wg/2007Jan/0078

PHB: difference between following link and typing URL
... if less-secure crypto in use then don't fool user
... into thinking it secure
... unless user has typed in e.g. https:// (maybe)

tlr: asks is this a use case?

silence aka ok-for-now

<scribe> ACTION: Hallam-Baker to draft differential use cases for security expectation vs. none [recorded in http://www.w3.org/2007/01/09-wsc-minutes.html#action06]

<trackbot> Created ACTION-69 - Draft differential use cases for security expectation vs. none [on Phillip Hallam-Baker - due 2007-01-16].

http://www.w3.org/2006/WSC/wiki/NoteUrlTypo

tlr: other use-cases need discuission (some anyway)
... any missing use-cases?

missing use cases?

tlr: what interactions are we missing?

silence; uncertainty

<beltzner> do we think IM lure is sufficiently different from email lure?

<beltzner> (I don't think it is, but in the interest of being complete ...)

<beltzner> +1 to merging them as per stuart's suggestion

Stuart: merge into out-of-band lure?

tlr: will you make this more generic?

Stuart: sure

<tlr> ACTION: Stuart to propose generalization of email lure [recorded in http://www.w3.org/2007/01/09-wsc-minutes.html#action07]

<trackbot> Created ACTION-70 - Propose generalization of email lure [on Stuart Schechter - due 2007-01-16].

tlr: I have a list...
... MITM (or something like it) detected
... or, what to do if cert looks odd
...another: TLS server proposes a new CA
... client accepts cert, wants more info about that
... user wants to check were a link leads, via status bar
... but what happens involves scripting

<scribe> ACTION: Farrell propose history related use-case [recorded in http://www.w3.org/2007/01/09-wsc-minutes.html#action09]

<trackbot> Created ACTION-71 - Propose history related use-case [on Stephen Farrell - due 2007-01-16].
