In a video presentation, Arnaud sheds light on the pivotal role of open-source software in modern software development, underscoring its ubiquitous presence across a myriad of applications. “Open source has evolved from being a mere component to a foundational pillar of the software supply chain,” Arnaud asserts. However, this meteoric rise is juxtaposed against a surge in cyber threats targeting vulnerabilities within open-source frameworks.

“The exponential growth of open source adoption has inadvertently expanded the attack surface, giving rise to a parallel increase in security vulnerabilities,” Arnaud notes, highlighting the alarming trend of vulnerabilities exploited through the software supply chain. As software dependencies increase, so does the imperative for robust security measures.

In response to this escalating threat landscape, industry stakeholders have rallied behind collaborative initiatives like the Open Source Security Foundation (OpenSSF), of which Arnaud is a distinguished member. “OpenSSH serves as a crucible for industry leaders to converge, collaborate, and address security challenges at scale,” Arnaud explains. By fostering cross-industry partnerships and knowledge sharing, OpenSSF endeavors to fortify the defenses of open-source software against emerging threats.

Moreover, regulatory interventions, such as the US executive order mandating software bill of materials (SBOM), have catalyzed efforts to enhance transparency and accountability in the software supply chain. “SBOM provides a critical framework for assessing and mitigating security risks associated with open source components,” Arnaud elaborates. By offering visibility into component provenance and vulnerabilities, SBOM empowers organizations to manage security threats and bolster resilience proactively.

Yet, Arnaud underscores that pursuing open-source security transcends regulatory compliance; it requires a holistic approach encompassing best practices, developer education, and innovative tools. Initiatives like the Scorecard project, championed by OpenSSF, equip stakeholders with the means to evaluate open-source projects’ security posture comprehensively. By fostering a culture of accountability and transparency, these initiatives pave the way for a more resilient open-source ecosystem.

Among the pioneering solutions driving the industry forward is the Six Store project, designed to streamline the signing and verification of software artifacts. By simplifying complex cryptographic operations, Six Store empowers developers to uphold the integrity and authenticity of software components, safeguarding against tampering and exploitation.

As the digital landscape continues to evolve, Arnaud emphasizes the imperative of collective action to fortify open-source security. “In an era defined by ubiquitous connectivity and interdependence, the security of open-source software is paramount,” Arnaud asserts. By fostering collaboration, innovation, and knowledge sharing, the industry stands poised to navigate the complexities of cyber threats and emerge more vital than ever before.

In a world where cybersecurity threats loom large, Arnaud’s insights serve as a guiding beacon, illuminating a path toward a more secure and resilient open-source ecosystem. Through unwavering dedication and concerted efforts, the industry can forge ahead, safeguarding the digital future for generations to come.

Rust is a popular programming language created by Graydon Hoare while he worked at Mozilla, with the organization sponsoring the effort. According to Phoronix, Torvalds has said Rust could be merged into the Linux kernel in 5.2.0.

The Linux kernel is currently written largely in the C programming language. Torvalds and other contributors played around with adding support for C++ some years ago before abandoning the effort.

Adding support for Rust would represent one of the biggest changes to the kernel in its history and would open the door for a number of significant improvements. Specifically, Rust was designed with safety and security in mind from the beginning. Rust has improved tools for memory management, built-in concurrency, and provides ownership and security paradigms. Its performance and low overhead also give it an advantage over many other languages.

These various advantages have all helped add impetus to Rust becoming the second language for developing the Linux kernel, with even Google throwing its weight behind it.

“We feel that Rust is now ready to join C as a practical language for implementing the kernel,” the company writes in its Security Blog. “It can help us reduce the number of potential bugs and security vulnerabilities in privileged code while playing nicely with the core kernel and preserving its performance characteristics.”

With Rust support in the kernel now in sight, Linux users should start seeing the benefits sooner rather than later.
