Hervé,

There is no Web Security Principle maintained on a regular basis by W3C.

All security principles are relying on the Same Origin Policy defined by IETF https://tools.ietf.org/html/rfc6454, plus security behavior designed in the WebAppSec WG, to which the UA can be compliant or not http://www.w3.org/2011/webappsec/.


The implementation of security in UA is left to the UA implementers and that is why in all W3C specification, you will find some security recommendations to the web app users, web app developers and UA implementers. UA implementers will find a message warning them that they have to implement things in a secure way, plus some obvious threats. Based on that, all the W3C specifications are taking the assumption that UA implementers are doing their best to deliver safe environments.

Hope it helps,
Virginie

Indeed, there seems to always be the assumption that the user-agent is secure and not compromised - and starting from that FIDO might be the cleanest possible design - but I don't see the perspective being on how to make internet usage more secure even if the user-agent is compromised, although there are technologies that will help if only they are brought to the open web.
Is there a principle in W3C that states that the user-agent not being compromised is always the assumption? (maybe it's part of the "Web security principles"?)

Cheers
Hervé

Hi,

Existing smart-card-using applications ranging from Windows login, SIM-cards in phones, EMV-cards in payment terminals, HTTPS Client Certificate Authentication in browsers, to the [now deprecated] custom signature browser-plugins, all share a common characteristic:
The smart card is accessed by "Trusted Code" which also holds associated UI.

Since the "Open Web" doesn't support this concept (transient web-code is by definition untrusted), it is not possible to continue without first having a firm plan on how to deal with "Trusted Code".

Sincerely,
Anders Rundgren
Principal,
