Codethink Ltd., a leading software services provider based in Manchester, UK, has announced that its Codethink Trustable Reproducible Linux (CTRL OS) system has successfully passed a safety baseline assessment conducted by exida, an independent third-party certification agency. The assessment confirmed that CTRL OS meets the stringent safety requirements of both IEC 61508 (SIL 3) and ISO 26262 (ASIL D) standards, making it the first Linux-based operating system to achieve this level of certification for use in highly critical systems and mixed-criticality environments. Event Background and Cause In today's tech landscape, especially in industries like automotive and industrial automation, ensuring the safety and reliability of systems is paramount. As the trend towards open-source technology continues to grow, the challenge of maintaining high safety standards has become increasingly significant. Codethink developed the CTRL OS to address this challenge, aiming to provide a trusted and robust Linux platform that can be reliably used in applications where system failures could have severe consequences. Initially, the solution was designed to meet the demand for a secure Linux platform in the automotive industry. However, over time, CTRL OS has evolved to cover a broader range of critical software modules, including infotainment systems, networking, and other safety-critical components. Assessment Process and Results The safety baseline assessment, conducted by exida, involved a detailed analysis of Codethink's security arguments and development methodologies. According to exida's standards, the assessment covered the entirety of the development process, from initial design to final testing, to ensure that CTRL OS meets the safety integrity levels required by IEC 61508 and ISO 26262. The results confirmed that CTRL OS can operate reliably in the highest safety categories, demonstrating its robustness and trustworthiness in extreme conditions. This achievement is particularly significant for sectors such as automotive, where safety certifications are crucial for market acceptance. Codethink's Strategic Goals Codethink's focus goes beyond mere compliance with safety standards. Paul Sherwood, the company's chairman, emphasized that their approach centers on building genuinely trustworthy and secure technologies. He stated, "Our ultimate aim is to establish confidence that the software will perform as intended and that any measures taken in response to issues will be reliable." Codethink's methodology involves reusing well-established open-source components, which allows companies to build and test complex systems at a lower cost and with reduced technical risk compared to proprietary solutions. This not only accelerates the development process but also ensures that the final product meets the highest safety benchmarks. Impact and Industry Response The success of the safety assessment has garnered significant praise from industry leaders. Jonathan Moore, Advanced Systems Director at exida, described Codethink's approach as groundbreaking, noting that it sets new standards for integrating safety and reliability in complex systems. Moore highlighted the importance of codifying trust through engineering practices rather than relying solely on audits or post-implementation checks. Other experts shared similar sentiments. C.J. King, Chief Technology Officer at Torc Robotics, emphasized that the certified Linux platform provides the necessary speed and flexibility for developing advanced autonomous vehicle systems. "This enables us to accelerate the development of our Level 4 truck autonomy platform while maintaining the highest safety standards," King said. David Nesbitt FREng, Director of Digital Product Platforms at Jaguar Land Rover (JLR), praised Codethink's long-term partnership and expertise, stating, "Their ability to deliver high-integrity integrated software solutions is vital, particularly in areas like infotainment, cockpit interfaces, and DevSecOps." Rebecca Rumbul, CEO of the Rust Foundation, also commended Codethink's work, stressing the value of combining strict engineering practices with open-source technology. "This demonstrates the tremendous potential of Safety Critical Rust and other initiatives to build safe, secure, and transparent technology," she noted. Codethink's achievement is seen as a major step towards changing the perception that open-source software inherently lacks the security and reliability of proprietary solutions. Broader Implications The successful safety assessment of CTRL OS is expected to boost the adoption of Linux in critical applications across various industries. It provides concrete evidence that open-source solutions can meet and exceed the safety requirements traditionally associated with proprietary software. By integrating safety and reliability from the early stages of development, Codethink has shown that these attributes can be achieved without compromising speed or flexibility. This is particularly beneficial for industries like automotive, healthcare, finance, and industrial automation, where the stakes of software failure are high. Daniel Izquierdo, CEO of Bitergia, pointed out that Codethink's efforts not only create reliable open-source technology but also demonstrate how to measure and improve it. "This inspires more companies to trust the values of transparency and community governance," he remarked. The milestone achieved by Codethink is a testament to the evolving landscape of software development, where open-source solutions are no longer viewed just as cost-effective alternatives but as integral components of safe and secure systems.
