Software Supply Chain Security Under the EU Cyber Resilience Act

The adoption of the EU Cyber Resilience Act (CRA) brings a much-needed focus on securing the software supply chain. IoT manufacturers depend heavily on third-party software (including both open-source libraries and proprietary code) to accelerate software development; however, limited visibility into components' origins and the security practices of their developers increases the potential attack surface and complicates risk mitigation.

High-profile incidents like SolarWinds and Log4j underscore the ways in which failure to address supply chain security can have devastating consequences. To mitigate supply chain risks, the CRA imposes strict requirements, which we’ll be looking at in more detail in this article. 

Non-compliance with these new rules may trigger substantial EU penalties - including fines up to (the greater of) 15 million Euros or 2.5% of global revenue and potential market exclusion, making it essential to stay on top of this new regulation.

This is part five of a six-part mini-series guiding IoT manufacturers through the intricacies of the EU CRA. Read part four here.

Key Requirements Under the EU CRA for Software Supply Chain Security 

Supplier Vetting and Risk Assessment

The CRA mandates comprehensive assessments of third-party suppliers, requiring detailed evaluations of their security policies, development methodologies, and incident response capabilities. Suppliers must demonstrate adherence to secure coding standards, vulnerability management processes, and regular security audits.

This vetting process isn't just limited to initial onboarding. Manufacturers must establish ongoing assessments, ensuring suppliers continuously comply with the latest security standards and practices. This includes analyzing suppliers’ use of subcontractors or open-source dependencies, which can introduce cascading risks into the supply chain.

Continuous Software Monitoring

Maintaining software integrity requires manufacturers to implement mechanisms for continuous tracking and assessment. The CRA requires automated tools to identify vulnerabilities, confirm the authenticity of software updates, and ensure no unauthorized changes are made to deployed components.

This also involves robust logging and auditing practices. (Logs should capture the provenance of all software updates, including metadata like time stamps and cryptographic signatures.) Additionally, manufacturers are encouraged to integrate continuous vulnerability scanning into their DevOps pipelines for real-time detection.

Transparent Documentation of Components

The CRA requires an up-to-date Software Bill of Materials (SBOM), documenting every software component's origin, version, and security status.

Documentation should also include relationships between components, identifying dependencies that could become vulnerable. The SBOM must also be machine-readable and easily accessible to regulatory authorities and customers, demonstrating transparency while safeguarding proprietary information.

Managing Open-Source Software (OSS) Risks

The CRA emphasizes the need for a structured approach to managing OSS. Manufacturers are required to ensure all OSS components are up-to-date, secure, and compliant with licensing terms.

Manufacturers must also monitor for “abandoned” OSS projects and have contingency plans to address security gaps through in-house updates or component replacement.
