This time, the 3mdeb’s stage belonged to Piotr Król (CEO of 3mdeb) who presented his adventures using Qubes OS as an everyday device, talking about USB camera and cryptocurrency wallets. Of course firmware-related topics could not be missing and Piotr also showed continuation of his previous year’s efforts of securing the VMs with SRTM and Secure Boot. The future of Qubes OS Summits Finally, the time has come when we may meet together in person, after three years! The Qubes OS Summit 2022 is fast approaching, with only a few days left before the start of the event in Berlin. As it is no longer held only virtually (but still possible to attend remotely for those who can’t be with us in person) the organization is more complicated, both from the logistics and presentations side. Every year we try our best to dig into hardcore security topics on the verge of firmware and operating systems. All this time we have been gradually building plans and ideas, and getting closer and closer to the goal of improving the security of Qubes OS, especially in areas we feel best at, i.e. SRTM and DRTM (AEM). In the upcoming event, we have prepared a few interesting projects and ideas around Anti Evil Maid support and open-source firmware on modern hardware. Here (cfp.3mdeb.com/qubes-o…schedule) you may find the full schedule. Among others we welcome the following speakers: Wessel Klein Snakenborg from Novacustom with a story of open-source on modern laptops as a candidate to Qubes OS certification Brent Cowing from Protectli talking about security of his small form factor computers also running open-source firmware Jan Suhr from Nitrokey talking about how enterprise requirements tied to Windows can be met with Qubes OS Arthur Rasmusson from Arc Compute talking about GPU virtualization and its possible benefits to Qubes oS Puck Meerburg from Spectrum OS telling about the power of Wayland for GUI isolation and how it benefits systems like Qubes OS or Spectrum OS And everyone from 3mdeb, Qubes OS team, and others We hope that the event and community around it and the Qubes OS project will grow in the future, bringing reasonable trustworthiness and collaboration for everybody. Definitely, 3mdeb will try its best to co-organize the event in the upcoming years. Summary By a mere coincidence, meeting Marek Marczykowski-Górecki gave birth to a fascinating series of Qubes OS Summits and led us to this day. Together with Invisible Things Lab we (3mdeb) are very proud to be the co-organizers of the 4th edition of the event. Looking forward to seeing each other again, but most important to talk and share knowledge and passion with everyone again after a long time. Many thanks to the Qubes OS team for holding up the tradition with us. See you all in Berlin!
