Free and Open-Source Software

Free and Open-Source Software (FOSS) refers to software whose source code is available for anyone to freely use, study, modify, and distribute. The core principle is 'free' as in freedom, not 'free of charge.' FOSS licenses vary widely, from permissive (e.g., MIT, Apache) to copyleft (e.g., GPL), which can pose legal risks if not managed correctly. Within risk management, FOSS is a critical part of the software supply chain. The international standard ISO/IEC 5230 (OpenChain) provides a framework for FOSS license compliance. For the automotive industry, ISO/SAE 21434 mandates continuous vulnerability management for all software components, including FOSS, to ensure cybersecurity. Therefore, effective FOSS management is crucial for legal compliance, product security, and corporate reputation.

In enterprise risk management, FOSS application focuses on systematically identifying and controlling its associated legal and security risks. Key implementation steps include: 1. Create a Software Bill of Materials (SBOM) using Software Composition Analysis (SCA) tools to identify all FOSS components, versions, and licenses. 2. Conduct compliance and vulnerability analysis by cross-referencing the SBOM against license databases and known vulnerabilities (CVEs), aligning with ISO/SAE 21434 risk assessment requirements. 3. Establish and enforce a FOSS governance policy that defines approved licenses, approval workflows, and vulnerability remediation SLAs. For example, a global auto parts supplier increased its first-pass rate for OEM cybersecurity audits to 98% and reduced mean-time-to-remediate critical vulnerabilities by 60% after implementing this process.

Taiwanese enterprises face three main challenges in FOSS management. First, a lack of expertise regarding complex FOSS licenses, leading to underestimated legal risks from copyleft licenses. Second, low supply chain transparency, as it is difficult to obtain complete SBOMs from upstream suppliers, which is a critical compliance gap under standards like ISO/SAE 21434. Third, resource constraints, particularly for SMEs, which hinder the adoption of automated SCA tools for efficient scanning. To overcome these, companies should start by establishing a FOSS governance policy and providing training. Next, integrate cost-effective SCA tools into the CI/CD pipeline for automation. Finally, contractually mandate SBOM delivery from all suppliers to ensure end-to-end supply chain security.
