Understanding the EU Cyber Resilience Act: What It Means for SBOMs

The EU Cyber Resilience Act (CRA) is a landmark regulation aimed at improving the cybersecurity of products with digital elements. It establishes stringent requirements for manufacturers, importers, and distributors to ensure that their products are secure throughout their lifecycle. A central aspect of this regulation is the requirement for a Software Bill of Materials (SBOM)—a detailed inventory of all software components used in a product.

Why SBOMs Are Critical

An SBOM provides transparency into the software supply chain by listing the components, libraries, and dependencies in a product. This visibility is crucial for identifying vulnerabilities, managing risks, and ensuring compliance with cybersecurity standards. Under the CRA, the importance of SBOMs is magnified as they form the foundation for demonstrating software integrity and security.

Key SBOM Requirements in the CRA

• Comprehensive Component List: Manufacturers must provide an accurate and up-to-date SBOM that includes all open-source and proprietary components. This ensures that stakeholders can assess potential vulnerabilities effectively.
• Support for Vulnerability Management: The SBOM must facilitate the identification of known vulnerabilities, allowing for quicker remediation. This aligns with the CRA’s emphasis on proactive risk management.
• Lifecycle Updates: SBOMs should be maintained and updated throughout the product’s lifecycle, reflecting any changes to the software environment, such as updates or patches.
• Accessible Documentation: The SBOM and related documentation must be easily accessible to regulatory bodies and, where applicable, end-users, ensuring compliance and transparency.

Implications for Businesses The CRA introduces an obligation to embed security-by-design principles into product development. By mandating SBOMs, the act ensures that businesses take accountability for their software supply chain. This could mean investing in tools to generate and maintain SBOMs, integrating them into CI/CD pipelines, and leveraging standards like CycloneDX or SPDX.

For companies in embedded systems or Industrial Control Systems (ICS), where the attack surface can extend to critical infrastructure, SBOMs will play a pivotal role in addressing compliance and minimizing risks.

Preparing for Compliance To comply with the EU CRA’s SBOM requirements:

• Adopt standardized formats like CycloneDX or SPDX
• Implement tools for automated SBOM generation and vulnerability scanning
• Develop processes for ongoing maintenance and verification of SBOMs

The EU Cyber Resilience Act signifies a step forward in securing digital ecosystems. For businesses, embracing SBOMs is not just about compliance — it’s about safeguarding trust and resilience in the face of evolving cyber threats
