The EU Cyber Resilience Act (CRA) makes creating Software Bill of Materials (SBOM) and technical documentation compulsory for any IoT manufacturer selling into the European Union. But this is more than just another regulation. The CRA's focus on SBOM and technical documentation represents a significant step toward imposing specific security requirements on software supply chain transparency. IoT manufacturers must see these requirements not just as a compliance checkbox but as an opportunity to demonstrate accountability and build more secure products.
This post is part three of a six-part mini-series that will guide IoT manufacturers through the EU Cyber Resilience Act’s requirements in detail. Read part two here.
Key Requirements for SBOM and Technical Documentation Under the EU CRA
- Comprehensive SBOM Creation
The EU CRA requires that manufacturers create and maintain SBOMs for each product, capturing every software component used in a device, from the operating system down to the smallest firmware module. This includes both proprietary and open-source components, with detailed metadata like version numbers, licensing information, and known vulnerabilities. Manufacturers must be able to account for every component at any given time, ensuring that vulnerabilities can be quickly identified and addressed before they cause widespread damage.
- Regular SBOM Updates
IoT devices are rarely static—they receive updates, patches, and new features over time. With each modification, the SBOM must be updated to reflect the current state of the device’s software. The CRA mandates this continuous updating to ensure that as new vulnerabilities are discovered, they can be traced back to the components listed in the SBOM. This ongoing process ensures that security flaws are quickly identified and resolved, minimizing risk for manufacturers and end-users.
- Detailed Technical Documentation
In addition to creating an SBOM, the CRA requires manufacturers to maintain detailed technical documentation. This documentation must include information on the device’s hardware and software configurations, security features, update protocols, and maintenance guidelines. The goal is to provide regulators with everything they need to evaluate the product’s security posture. Inadequate or missing documentation could result in regulatory penalties and delay time-to-market for new products.
- Accessible Documentation for Regulatory Audits
The CRA doesn’t just require documentation; it demands that this information be easily accessible for regulatory audits. Manufacturers must maintain a centralized repository for all technical documentation and SBOMs, ensuring they can quickly provide evidence of compliance if requested. Producing this documentation promptly is critical for passing regulatory inspections and avoiding fines or sanctions.
EU CRA Compliance Tips for IoT Manufacturers
- Automate SBOM Generation
One of the best ways to ensure compliance is by automating SBOM generation. IoT manufacturers can use tools, like Finite State, that automatically scan software components during development, continuously updating the SBOM as changes are made. This process eliminates manual errors and ensures that SBOMs remain accurate and consistent. By integrating these tools directly into the development pipeline, manufacturers can streamline the process of keeping their SBOMs up to date with every product iteration or software patch.
- Implement SBOM Management Processes
Compliance with the CRA requires more than just generating an SBOM—it’s about managing it effectively. Manufacturers must establish processes that ensure the SBOM is reviewed and updated regularly, particularly after product updates or vulnerability disclosures. This could involve automated notifications to security teams when a new vulnerability is discovered or integrating SBOM management into the CI/CD pipeline to ensure every new release has an up-to-date SBOM.
- Establish Comprehensive Technical Documentation Protocols
IoT manufacturers should develop a standardized documentation process that covers all aspects of the device's configuration, security features, and update procedures. This ensures that the documentation meets CRA standards, making it easier for security teams to identify potential risks and for regulators to assess compliance.
- Prepare for Audits
Regulatory audits can be daunting, especially when manufacturers are scrambling to gather the required documentation. The key to successful audit preparation is organization. Implementing a centralized documentation repository allows manufacturers to keep all SBOMs and technical documents in one place, making them easily accessible for both internal teams and auditors. This approach streamlines compliance and reduces the risk of non-compliance due to lost or outdated documentation.
How Finite State Helps IoT Manufacturers Comply with the SBOM and Technical Documentation Requirements of the EU Cyber Resilience Act (CRA)
One of the most critical aspects of CRA compliance is generating and maintaining accurate Software Bill of Materials (SBOM) and technical documentation that reflects current vulnerability data. Here’s how Finite State can help:
Automated SBOM Generation and Management
Finite State’s platform is designed to automate the generation and management of SBOMs for IoT devices, ensuring manufacturers meet the EU CRA requirements without the usual manual effort. By integrating both source code and binary analysis, the platform provides a comprehensive view of all software components within a product. More importantly, it continuously enriches these SBOMs with vulnerability data. This dynamic tracking of components ensures that IoT manufacturers maintain an up-to-date understanding of vulnerabilities in both open-source and proprietary software, enabling proactive risk mitigation. This automation saves time, reduces human error, and ensures full compliance with CRA requirements, which demand transparent and detailed documentation of every software component.
Continuous Vulnerability Detection and Tracking
One of the most daunting aspects of compliance is the requirement to keep vulnerability data current, especially as new threats are discovered. Finite State continuously monitors for vulnerabilities, integrating this information directly into the SBOM so manufacturers don’t have to scramble to update documentation with every new CVE. This approach helps meet CRA standards and ensures that technical documentation is always up-to-date, significantly reducing the risks posed by unpatched vulnerabilities. With MergeBase technology now part of the mix, Finite State strengthens this capability by providing advanced insights into vulnerabilities affecting both source code and third-party libraries.
Reporting Tools for Audit Readiness
When it comes to audit preparedness, Finite State’s platform offers an edge with its comprehensive compliance reporting features. These tools are built to streamline the audit process, enabling IoT manufacturers to quickly generate detailed reports that support organizational efforts to align with EU CRA standards. Whether preparing for internal audits or external reviews, the platform provides a clear and consolidated view of software composition and vulnerability data, helping to ensure that manufacturers can demonstrate compliance with minimal effort and reducing the overall burden on their teams.
By leveraging Finite State's automated SBOM management, continuous vulnerability tracking, and audit-ready reporting, IoT manufacturers can confidently navigate the complexities of the EU CRA, ensuring both security and compliance are seamlessly integrated into their development lifecycle.
