February 25, 2021: We are happy to announce of first keynote speaker: Christoph Kerschbaumer from Mozilla!

February 25, 2021: This year, SecWeb will feature a mentoring program for junior members of the community to be exposed to the reviewing process. If you are a student working on Web security or are the supervisor of students working on Web Security, please reach out via email to us (chairs(at)secweb(dot)work) to indicate interest.

February 22, 2021: We'll have a second edition of SecWeb, again co-located with EuroS&P!. We are also releasing a preliminary CfP today.

SecWeb Reviewing Mentoring

Reviewing is hard, constructive reviewing even more so. For SecWeb, we therefore will have a mentoring program for junior members of the community. We will invite a limited number of students in the area of Web security into the PC and each junior member will have a mentor which whom to discuss their reviews. In this way, junior community members are exposed to the reviewing and discussion process, while also benefiting from the experience and insights of more senior reviewers. If you or your students are interested in this, write an email to chairs(at)secweb(dot)work by March 15 to indicate your (or your students') interest.

What is SecWeb?

Back in the days, the Web was not designed with security or privacy in mind. Many key mechanisms we rely on today for critical functionality were arguably not designed for security (such as cookies for authentication purposes) and numerous mechanisms have been piecemeal retrofitted to the Web to add security to it. In this workshop, we want to move away from augmenting the Web with Security and rather design Security for the Web.

Aim & Scope

The Web has become the key access point to a plethora of security-sensitive services, which we use on a daily basis, yet it was not designed with security in mind. Over the years, this has led to many security mechanisms which were piecemeal retrofit to not cause breakage to existing web applications. The goal of the SecWeb workshop is therefore twofold: we want to collect ideas on how the Web could be extended with novel security mechanisms, better access interfaces (browsers) and disciplined programming abstractions, so as to natively support secure web application development. Moreover, we also invite in particular contributions which aim to redesign parts of the ecosystem, so as not to be stuck on a patchwork of security on the Web, but rather have security built-in by design.

Besides traditional Web security papers, SecWeb particularly welcomes position papers which propose provocative thoughts on how (parts of) the current web platform could be heavily re-envisioned for security. Such proposals often do not fit major computer security conferences, because their real-world deployment might be complicated, yet they have value for the web security community, since they advance the understanding of relevant web security problems, their root causes and the design space of possible solutions. Ideally, we expect well-thought proposals accepted at SecWeb to be excellent starting points for discussion with browser vendors (which we explicitly envision as participants) and/or major players of the Web market, who have the commitment and the resources to convert academic proposals into reality.

13:40 - 14:20 Keynote: Web tracking, consent pop-ups and dark patterns: legal and technical perspectives
As millions of users browse the Web on a daily basis, they become producers of data that are continuously collected by numerous companies and agencies. Website owners, however, need to become compliant with recent EU privacy regulations (such as GDPR and ePrivacy) and often rely on consent pop-ups to either inform users or collect their consent to tracking.

This talk delves into the subject of compliance of tracking technologies and consent pop-ups with the GDPR and ePrivacy Directive, and offers a multi-disciplinary discourse from legal, technical and even design perspective. We present our recent works on detection of Web tracking, compliance of consent pop-ups, and identification of gaps between law, design and technology when dark patterns are used in consent pop-ups.

This talk covers our recent publication in computer science, law and human-computer interaction domains:

17:30 - 18:00 Keynote: The Road to a secure Web
The Hypertext Transfer Protocol, generally displayed as http in a browsers address-bar, is the fundamental protocol through which web browsers and websites communicate. However, data transferred by the regular http protocol is unprotected and transferred in cleartext, such that attackers are able to view, steal, or even tamper with the transmitted data.

Carrying http over the Transport Layer Security (TLS) protocol, generally displayed as https in the address-bar of a browser, fixes this security shortcoming by creating a secure and encrypted connection between the browser and the website.

Over the past few years we have witnessed tremendous progress towards migrating the web to rely on https instead of the outdated and insecure http protocol. Within this talk we will highlight initiatives from browser vendors as well as community efforts to accelerate the migration from http to https. We will conclude by answering the question of how much further we have to continue on this road to reach our destination: a secure Web.

Logistics & Dates

SecWeb 2021 is co-located with IEEE EuroS&P 2021 and scheduled for September 6, 2021.

Important Dates

  • Paper submissions due: May 28 June 11, 2021 (15:59 CET) via HotCRP
  • Notification to authors: July 2, 2021
  • Camera-ready deadline for accepted papers: July 16, 2021

Call for Papers

All papers discussing Web security and Web privacy aspects are solicited for submission. SecWeb particularly welcomes position papers which propose provocative thoughts on how (parts of) the current Web platform could be heavily re-envisioned for security. This explicitly includes proposals that would break today’s Web to improve its security tomorrow.

Topics of interest include, but are not limited to, the following:

  • Browser security
  • Formal methods for Web security
  • Language-based Web security
  • Security policies for the Web
  • Usable Web security
  • Web application firewalls
  • Web attacks and defenses
  • Web authentication and authorization
  • Web protocol security
  • Web security architectures
  • Web tracking and online advertisement

Reviewing and Publication Process

SecWeb solicits both full and short papers. All papers must be written in English and must not exceed 10 pages (full) and 6 pages (short) in A4 format using the IEEE conference proceeding template (excluding bibliography and well-marked appendixes). Submissions must be in PDF format and should print easily on simple default configurations. Submissions are anonymous, so information that might identify the authors must be excluded. It is the authors' responsibility to ensure that their anonymity is preserved when citing their own work. Failures to adhere to these requirements can be grounds for rejection.

The proceedings will be published by the IEEE after the workshop and will be made available in IEEE Xplore. During submission, authors can choose to have their paper excluded from the proceedings. At least one author of each accepted paper must register to the workshop for presentation.

All submissions considered for inclusion in the proceedings must contain an original contribution. That is, these papers must not substantially overlap papers that have been published or that are simultaneously submitted to a journal, conference or workshop. In particular, simultaneous submission of the same work is not allowed. This requirement is relaxed for submissions which will not be included in the proceedings: in particular, we also invite papers that are currently under submission or planned to be submitted before the SecWeb notification.
