The latest Census report on free and open-source software (FOSS) has shed light on the evolving landscape of open-source components, revealing a significant shift towards memory-safe programming and highlighting lingering security concerns. The Census III of Free and Open Source Software: Application Libraries, produced by The Linux Foundation in partnership with the Open Source Security Foundation (OpenSSF) and Harvard University, is based on an unprecedented 12 million data points from software composition analysis (SCA) and application security tools.

The report's findings are striking, particularly in the area of programming languages. Rust, a memory-safe language, has seen a surge in adoption, indicating a growing recognition of the importance of memory safety in production codebases. This trend is significant, as memory safety issues are a common vulnerability in software development.

However, the report also highlights a persistent security concern: the continued reliance on Python 2. Despite its end-of-life status, Python 2 remains widely used, posing a significant risk to the security of production codebases. The lack of standardized naming for components is another area of concern, as it increases the risk of dependency confusion and malicious package injection.

The Census III report is the latest installment in a series, following previous reports in 2015 and 2020. The Linux Foundation's efforts to track the prevalence of open-source components provide a vital understanding of the ecosystem, which is essential for identifying and mitigating security risks. The report's findings will likely have significant implications for the development community, as it underscores the need for more secure and sustainable practices in open-source software development.

The report's methodology is noteworthy, leveraging data from prominent SCA and application security tools such as Black Duck, FOSSA, Snyk, and Sonatype. These tools have been deployed at over 10,000 companies, providing a comprehensive view of open-source component usage in production codebases. The report's findings are a testament to the power of data-driven insights in shaping the future of software development.

The full report is now available for download, offering a wealth of information for developers, security professionals, and industry stakeholders. As the open-source ecosystem continues to evolve, the Census III report serves as a timely reminder of the importance of prioritizing security and sustainability in software development.

In conclusion, the Census III report paints a nuanced picture of the open-source component landscape, highlighting both positive trends and lingering security concerns. As the development community continues to grapple with the challenges of secure and sustainable software development, this report provides a vital roadmap for navigating the complexities of open-source software.
