The US Cybersecurity and Infrastructure Security Agency (CISA) has recently introduced the Hardware Bill of Materials (HBOM) Framework   . This voluntary framework aims to enhance communication between technology hardware vendors and customers , with the goal of reducing risks in the US supply chain.
Developed by the Information and Communications Technology Supply Chain Risk Management Task Force within CISA , the HBOM Framework establishes standardized guidelines for customers and suppliers in the hardware technology industry . By standardizing component attributes and providing information about different types of components , this framework improves the accuracy of risk assessments related to hardware products . Additionally, it includes guidelines on the necessary HBOM information based on its purpose and offers a tool for vulnerability checks and regulatory compliance.
While the HBOM Framework has been viewed positively by some experts, concerns have been raised regarding its inability to trace HBOMs throughout a product’s life cycle. This highlights the need for a software equivalent to effectively manage the complexity of digital supply chain risk .
The introduction of the HBOM Framework by CISA is a significant step towards standardizing communication and mitigating risks in the US supply chain. By providing codified standards and guidelines, this framework enhances the accuracy of risk assessments and promotes regulatory compliance. However, the lack of traceability throughout a product’s life cycle calls for the development of a software solution to address the complexities of digital supply chain risk. Moving forward, it is crucial to consider the impacts, potential mitigations, and future implications of the HBOM Framework in order to further strengthen cybersecurity and protect critical infrastructure.
