RAFIA – A Roadmap for Certifying Open Source for Use in Safety-Relevant Systems (video)

By August 16, 2023October 3rd, 2023Blog, Safety-Critical Software Summit

The Linux Foundation hosted the Embedded Open Source Summit (EOSS), a new umbrella event for open source embedded projects and developer communities to come together under one roof for important collaboration and education, in Prague, Czech Republic, on June 27-30. More than 1,300 people registered for the conference – representing 375 organizations across 56 countries around the globe.

EOSS hosted the Safety-Critical Software Summit, which was sponsored by the ELISA Project, that gathered safety experts and open source developers to enable and advance the use of open source in safety-critical applications. As part of the Summit, Paul Sherwood, Chairman of Codethink, presented a session titled, “RAFIA – A Roadmap for Certifying Open Source for Use in Safety-Relevant Systems.”


Many organizations would like to deploy open source software in safety-relevant systems, but face extreme challenges in demonstrating that the results would be safe and compliant with relevant standards such as ISO 61508 and ISO 26262.

In this video, Paul explains RAFIA (Risk Analysis, Automated Testing, Fault Injection, Mitigation and Compliance), a methodology devised by Codethink and shared in public via the ELISA Project, which helps us to establish confidence in the use of open source software to support specific safety goals and demonstrate compliance with applicable standards. The component steps of RAFIA will be covered in detail with examples, as well as lessons learned by Codethink in developing and applying the process for an embedded Linux-based operating system supporting a safety-relevant in-vehicle workload.
