Some things I find from a search engine, but others I type in - like my bank, my company website, my drug website, even tvguide.com _____ From: public-usable-authentication-request@w3.org [mailto:public-usable-authentication-request@w3.org] On Behalf Of Mary Ellen Zurko Sent: Thursday, April 26, 2007 9:13 AM To: beltzner@mozilla.com Cc: public-usable-authentication@w3.org Subject: Re: DNSSEC indicator Must be a lot of people who watch TV commercials and go to movies in the US type in URLs. I see every movie commericial ending in one.

The client should - when DNSSEC actually exists in the wild - be modified such that its presence or absence can be used to provide the client (not the poor user, who doesn't care about the topsy-turvy world of TCP/IP) with an additional criteria on which to base its security policy in terms of how to treat the source content. This is purely an implementation detail at the connection later plugging what Dick correctly termed a "leaky hole". Oh, and in answer to the question of "who still types in URLs these days?", it turns out that quite a lot of people do. By some metrics, as many as 30% of starting a task pageloads. cheers, mike -----Original Message----- From: <sthomas2@ups.com> Date: Thu, 26 Apr 2007 08:19:32 To:<public-usable-authentication@w3.org> Subject: RE: DNSSEC indicator Dick is quite right. DNSSEC could indeed provide another tool in the toolbox to make sure that the network is doing what the user really wants. My issue, though, is elevating the DNSSEC status to a human-visible indication. The more indicators that are displayed to a user, the less likely the user is to pay attention to them. Research is already showing that users are ignoring the indications that browsers give them today. For that reason, browser designers need to be very parsimonious in displaying security indications and focus on showing information that is really important. Given the relative rarity of attacks involving improper name resolutions, a DNSSEC indication would not seem to have enough value to justify its use.

It is useful to know that the client really is connected to www.micros0ft.com if that is what the client wants to connect to. DNSSEC is not going to solve social phishing attacks, but it does enable other technology such as CardSpace etc. to have increased certainty on what is going on. -- Dick
