Gregor "Little Detritus" Bransky

Gregor “Little Detritus” Bransky likes to build platforms and infrastructures. Preferably decentralized and including physical components.

He has been active in Open Source Projects since 2017. He started as part of the Freifunk community, working on Wifi4EU to ease the access to Wi-Fi in public spaces [a].

Since 2020 he joined Germanys civic-tech scene through the #wirvsvirus hackathon. As an early member of the “InÖG - Innovationsverbund Öffentliche Gesundheit e.V.” [b] he is currently serving as the board member for press and policy.

In this capacity he is responsible for the project, “B3 - Buntes Bug Bounty”, a cooperation with the BSI - Germanys cybersecurity agency – in the framework of BSIs annual Cybersicherheitsdialog. For more information, please visit the project websites of both partners [c][d].

He earns his money working as a freelance interim manager for research consortia in the field of digital platforms and infrastructures.



A security.txt for gits?
Gregor "Little Detritus" Bransky

We want to propose to start the discussion on a machine-readable standardized addition to git repositories which will serve two purposes:

a) Coordinated Vulnerability Disclosure
Provide necessary information for an anonymous, easy access, legally secure and ethical CVD process.

b) Up- & Downstream Vulnerabilities
Allow projects using the code to receive reports on vulnerabilities in a feed before the CVE is public.

Cunningham's Law states "the best way to get the right answer on the internet is not to ask a question; it's to post the wrong answer." we ask this talk to be understood in this sense. Pls let us know how this would be done proper in the linked issues (CVD, Up- & Downstream Vulnerabilities)

To our understanding, securing FOSS requires two kinds of measures. Preventive measures like pen-tests and audits, and reactive measures like CVD process and up- and down streaming relevant information.

Why do we care about this?

The “InÖG - Innovationsverbund Öffentliche Gesundheit e.V.” is a german based open-source project working on GovTech solutions for administration2X communication, since 2021.

Our solution IRIS-Connect [1] ran in 54 public health centers in four states (North Rhine-Westphalia, Hessian, Saxony, and Thuringia) serving 30.4 million German citizens as the link between public health centers and contact tracing apps.

To us security questions were central due to two main reasons:

A) The sensitive information, including health data IRIS-connect handled.
B) The non-negligible attack surface of public health centers

Due to A) IRIS offers E2EE communication between public health centers and apps used by the population at large. The relevance of the second point was stressed by the known vulnerabilities reported in similar solutions [2].

Given this situation, the government institutions interested in using our software wanted to know “whom they could call” if something is wrong. Given the imminent situation, we were able to find practical short time solutions but the issue remains. Especially with the EU's Cyber Resilience Act [3] on the horizon, the question of how to reach out to OSS projects will become more relevant.

For a more comprehensive view on the challenges of FOSS procurement, please see Miriam Swyffarths talk: ”Why isn't the German administration procuring more FOSS?”

This talk is part of the InÖGs current cooperation with the BSI - Germanys cybersecurity agency – in the project “B3 - Buntes Bug Bounty” as part of the BSIs annual Cybersicherheitsdialog. For more information, please visit the project websites of both partners [4][5]. We acknowledge funding by the BSI in the form of reimbursements of expenses of the volunteering contributors.

Stage 2
On the Shoulders of Giants: Security in FOSS
Thomas Fricke, Isabel Drost-Fromm, Gregor "Little Detritus" Bransky

In a world where we stand on the shoulders of giants, where we build systems that are increasingly interconnected, supply chain security is becoming more and more important. As Free and Open Source projects, we believe that we can lead the way for the industry in terms of processes, best practices and technology patterns.

In this open panel, we want to discuss the importance of security in Free and Open Source Software projects. We want to encourage participants of FOSS Backstage to share their questions and insights about topics like supply chain security, security processes, vulnerability disclosure, bug bounties and more.
