Is Open Source a Threat to National Security?
Open-source software is a lifesaver for startups and enterprises alike as they attempt to deliver value to customers faster. While open source use isn’t considered dubious for business use like it once was, the very open nature of it leaves it open to poisoning by bad actors. “Open-source AI and software can present serious national security risks — particularly as critical infrastructure increasingly relies on them. While open-source technology fosters rapid innovation, it doesn’t inherently have more vulnerabilities than closed-source software,” says Christopher Robinson, chief security architect at the Open Source Security Foundation (OpenSSF). “The difference is open-source vulnerabilities are publicly disclosed, while closed-source software may not always reveal its security defects.” Incidents such as XZ-Utils backdoor earlier this year demonstrate how sophisticated actors, including nation-states, can target overextended maintainers to introduce malicious code. However, the XZ-Utils backdoor was stopped because the open-source community’s transparency allowed a member to identify the malicious behavior. “At the root of these risks are poor software development practices, a lack of secure development training, limited resources, and insufficient access to security tools, such as scanners or secure build infrastructure. Also, the lack of rigorous vetting and due diligence by software consumers exacerbates the risk,” says Robinson. “The threats are not limited to open source but extend to closed-source software and hardware, pointing to a broader, systemic issue across the tech ecosystem. To prevent exploitation on a national level, trust in open-source tools must be reinforced by strong security measures.” Related:Let’s Revisit Quality Assurance Open Source: Get What You Paid For? A primary threat is the lack of support and funding for open-source maintainers, many of whom are unpaid volunteers. Organizations often adopt open-source software without vetting security, assuming volunteers will manage it. Another often overlooked issue is conflating trust with security. Simply being a trusted maintainer doesn’t ensure a project’s security. Lawmakers and executives need to recognize that securing open source demands structured, ongoing support. “AI systems, whether open or closed source, are susceptible to prompt injection and model training tampering. OWASP’s recent top 10 AI threats list highlights these threats, underscoring the need for robust security practices in AI development. Since AI development is software development, it can benefit from appropriate security engineering,” says Robinson. OWASP is the Open Worldwide Application Security Project. “Without these practices, AI systems become highly susceptible to serious threats. Recognizing and addressing these vulnerabilities is essential to a secure open-source ecosystem.” Related:Soft Skills, Hard Code: The New Formula for Coding in the AI Era At the company level, boards and executives need to understand that using open-source software involves effective due diligence and monitoring and contributing back to its maintenance. This includes adopting practices like creating and sharing software bills of materials (SBOMs) and providing resources to support maintainers. Fellowship programs can also provide sustainable support by involving students or early-career professionals in maintaining essential projects. These steps will create a more resilient open-source ecosystem, benefiting national security. “Mitigating threats to open source requires a multifaceted approach that includes proactive security practices, automated tools, and industry collaboration and support. Tools like OpenSSF’s Scorecard, GUAC, OSV, OpenVEX, Protobom, and gittuf can help identify vulnerabilities early by assessing dependencies and project security,” says Robinson. “Integrating these tools into development pipelines ensures that high-risk issues are identified, prioritized and addressed promptly. Additionally, addressing sophisticated threats from nation-states and other malicious actors requires collaboration and information-sharing across industries and government.” Related:Develop an Effective Strategy for User Self-Help Portals Sharing threat intelligence and establishing national-level protocols will keep maintainers informed about emerging risks and better prepared for attacks. By supporting maintainers with the right resources and fostering a collaborative intelligence network, the open-source ecosystem can become more resilient. Infrastructure Is at Risk While the widespread use of open-source components accelerates development and reduces costs, it can expose critical infrastructure to vulnerabilities. “Open-source software is often more susceptible to exploitation than proprietary code, with research showing it accounts for 95% of all security risks in applications. Malicious actors can inject flaws or backdoors into open-source packages, and poorly maintained components may remain unpatched for extended periods, heightening the potential for cyberattacks,” says Nick Mistry, CISO at software supply chain security management company Lineaje. “As open-source software becomes deeply embedded in both government and private-sector systems, the attack surface grows, posing a real threat to national security.” To mitigate these risks, lawmakers and C-suite executives must prioritize the security of open-source components through stricter governance, transparent supply chains and continuous monitoring. Dependencies Are a Problem Open-source AI and software carry unique security considerations, particularly given the scale and interconnected nature of AI models and open-source contributions. “The open-source supply chain presents a unique security challenge. On one hand, the fact that more people are looking at the code can make it more secure, but on the other hand, anyone can contribute, creating new risks,” says Matt Barker, VP & global head, workload identity architecture at machine identity security company Venafi, a CyberArk Company. “This requires a different way of thinking about security, where the very openness that drives innovation also increases potential vulnerabilities if we’re not vigilant about assessing and securing each component. However, it’s also essential to recognize that open source has consistently driven innovation and resilience across industries.” Organizational leaders must prioritize rigorous evaluation of open-source components and ensure safeguards are in place to track, verify, and secure these contributions. “Many may be underestimating the implications of mingling data, models, and code within open-source AI definitions. Traditionally, open source is applied to software code alone, but AI relies on various complex elements like training data, weights and biases, which don’t fit cleanly into the traditional open-source model,” says Barker. “By not distinguishing between these layers, organizations may unknowingly expose sensitive data or models to risk. Additionally, reliance on open source for core infrastructure without robust verification procedures or contingencies can leave organizations vulnerable to cascading issues if an open-source component is compromised.” Thus far, the US federal government has not imposed limits
