      An Inquiry into the Nature and the Causes of Web Insecurity

Abstract

   The year 2011 has been quite exciting from a Web security point of
   view: a number of high-profile security incidents have gotten a lot
   of press attention but also new initiatives, such as the National
   Strategy for Trusted Identities in Cyberspace (NSTIC), had been
   launched to improve the Web identity eco-system.  The NSTIC strategy
   paper, for example, observes problems with Internet security due to
   the widespread usage of low-entropy passwords and the lack of widely
   deployed authentication and attribute assurance services.

   With this memorandum we try to develop a shared vision for how to
   deal with the most pressing Web security problems.

1.  Introduction

   HTTP is an IETF standard and documented in RFC 2616 [RFC2616] and
   provides the core foundation of the browser-based platform but is
   also widely used for non-browser-based applications in smart phones
   and Internet tablets.  Like any other specification in the IETF HTTP
   also comes with various security mechanims.  Digest authentication
   support in HTTP was published in 1997 with RFC 2069 [RFC2069] and
   later updated in 1999 by RFC 2617 [RFC2617].  The HTTP state
   management mechanism, namely cookies, was initially published in 1997
   with RFC 2109 [RFC2109], and re-written in 2000 by RFC 2965
   [RFC2965].

   For client side authentication two different solution tracks have
   therefore been offered from the IETF, namely TLS client side
   authenication (at that time the usage of client certificates was
   envisioned) and also application level authentication via HTTP basic
