The Point: Component and hardware bills of materials (CBOM/HBOM) reduce delays in security risk assessment through systematic transparency of dependencies used.
CBOM and HBOM transparently document dependencies in IT infrastructures. When critical vulnerabilities affect widely distributed components, these bills of materials enable rapid assessments of an organization’s own exposure.
Vulnerabilities in widely used components typically create uncertainty for CISOs about their own level of risk: a vulnerability is known, but it remains unclear whether and to what extent their own IT infrastructure actually uses the affected module.
Component Bill of Materials (CBOM) and Hardware Bill of Materials (HBOM) systematically document which components and dependencies exist in the infrastructure. A CBOM captures software components, libraries and their versions; an HBOM documents physical hardware, firmware and embedded systems.
With such bills of materials, security risks can be assessed faster: instead of manually searching individual systems for affected components, a CBOM or HBOM can be queried directly. This significantly shortens response time and enables prioritization of patching and mitigation measures based on available inventory data.
