This is the tech blog for Center for Digital Resilience, where we discuss development of the CDR Link platform and related projects.

  • CDR Link 1.0 is released!

    CDR Link has reached 1.0 status!

    Wait - what is CDR Link?

    The CDR Link platform is for anyone wishing to offer their community a secure, multi-channel, mobile-first way to get in touch and ask for assistance. It enables an easy way for communities to ask for help and for responder to provide it. It’s super flexible and we’re excited to hear how people will be using it.

    This release is the culmination of about two years’ of work from concept to development to beta release to, finally, the 1.0. The CDR team – including the development team at Guardian Project – is excited to debut it!

  • An ecosystem of extensions

    As we’ve mentioned before, CDR Link adheres to the Unix-like philosophy of utilizing an ecosystem of small, repurpose-able programs that handle discreet tasks well, rather than producing one monolithic thing that does many things badly.

    In software, the gold standard of this philosophy is the Debian project, in which thousands of volunteers maintain small programs that, in the aggregate, combine to form the Debian (GNU-Linux) operating system. If these volunteers worked to produce a single “blob” of a operating system, like macOS or Windows, that system would be less stable, less secure, and less flexible.

    CDR Link isn’t Debian, but we strive to apply the same philosophy.

  • Leafcutter: The glue binding the data together

    CDR Link isn’t a single platform, it’s an ecoystem of interconnected technologies and data streams. Users file tickets in Zammad via extensions integrating email, web forms, Signal, WhatsApp, and Telegram. That data will be scrubbed and normalized and sent to MISP, the open-source threat sharing and analysis database. Third-party data from trusted parters will combine with ticketing data in MISP. All datasets will be made accessible for analysis and sharing with the non-technical community via a data usability and accessibility layer.

    Our name for the glue joining together all of these pieces is “Leafcutter.”

  • What is CDR Link?

    Our technology work at the Center for Digital Resilience centers on development of the “CDR Link” project. Link is an ecosystem comprised of a number of open source tools that address number of current challenges facing the civil society incident responder community.
