STPA Safety

How Codethink are using STPA for risk analysis of software-intensive systems and integrating the outputs into the engineering process.

Applying functional safety practices to modern software-intensive systems requires a different approach to the established methods enshrined in current safety standards. Codethink have been working with Exida on a new approach to software safety for systems based on Linux.

Hypocrite Commits Thumbnail

The recent furore around University of Minnesota’s “Hypocrite commits” research, which spilled over from the Linux Kernel Mailing List and into mainstream tech media, has provoked a lot of discussion about the Linux kernel community’s processes, and arguably provided ammunition to folks who have been saying all along that open source software cannot be trusted.

Safety Devroom Thumbnail

Codethink recently ran the Safety and Open Source devroom at FOSDEM 2021. Unfortunately, due to Covid-19, this was entirely virtual. However, this did make the conference more accessible to those who would otherwise be unable to attend. 2021 was the first year that the safety devroom had been run, and hopefully, it will become a regular occurrence at FOSDEM in future years.

Applying functional safety practices to software-intensive systems can be very challenging, and established approaches have struggled to scale and adapt to the problem. But what is meant by the assertion that "Safety is a system property, not a component property" and how should this shape our understanding of safety when applied to software?

In this episode of 'Meet the Codethings', we've asked Shaun about FOSDEM, the future of safety-critical software in automotive, and STPA. Keep up-to-date with our news about safety by just subscribing to our Safety newsletter at the end of the article.

FOSDEM devroom Safety and Open Source Software Thumbnail

FOSDEM is a two-day event organised by the FOSS community for FOSS the community. This event aims to gather like-minded professionals to learn, teach, and broaden their knowledge and network. This is a fun and exciting weekend for the developers and our employees since they are hosting their first devroom this year.

FOSDEM is coming, 6th and 7th of February 2021! In addition to attending the virtual event, this time Codethink engineers will be curating the Safety and Open Source Software Dev Room.

I recently digitally attended the 2020 STAMP workshop, hosted by MIT. This was originally planned to be in Boston in March, but for obvious reasons was moved.

In 2018, Codethink worked with Lukas Bulwahn from BMW on a project investigating some core functionality of the Linux kernel that is relevant to safety considerations of an assumed system. We wanted to share some of our findings from this work, as it could prove useful to communities interested in using Linux in a safety-critical context.

Masks, coronavirus and smartphone

As concerns about the privacy and security implications of contract tracing apps for COVID-19 show, establishing trust in software is still a real challenge. I’ve been following reports about these apps closely, and have been interested to read medical, technical and ethical analysis from around the world. What all of these perspectives underline for me is the critical role of public trust in the success or failure of such applications.

As a result of collaborative research with MIT, Codethink announces a new open source project AV-STPA, to analyse and document safety requirements for autonomous vehicles by applying System-Theoretic Process Analysis.

On our continuing journey to understand the implications of safety and security risk management for complex software-intensive systems, Codethink has …

Systems are becoming more complex than ever before. This now allows us to accomplish tasks that once seemed impossible. With this increase in complexity from systems, there is a need for safety models that can keep up.
