OWASP CycloneDX is a full-stack Bill of Materials (BOM) standard that provides advanced supply chain capabilities for cyber risk reduction. The specification supports:
- Software Bill of Materials (SBOM)
- Software-as-a-Service Bill of Materials (SaaSBOM)
- Hardware Bill of Materials (HBOM)
- Machine Learning Bill of Materials (ML-BOM)
- Cryptography Bill of Materials (CBOM)
- Manufacturing Bill of Materials (MBOM)
- Operations Bill of Materials (OBOM)
- Vulnerability Disclosure Reports (VDR)
- Vulnerability Exploitability eXchange (VEX)
- CycloneDX Attestations (CDXA)
Modern software is assembled using third-party and open source components, glued together in complex and unique ways, and integrated with original code to achieve the desired functionality. An accurate inventory of all components enables organizations to identify risk, allows for greater transparency, and enables rapid impact analysis.
CycloneDX was created for this purpose.
Strategic direction and maintenance of the specification is managed by the CycloneDX Core Working Group, is backed by the OWASP Foundation, and is supported by the global information security community.
The CycloneDX project maintains a list of achievable use cases. Examples for each use case are provided in both XML and JSON.
The CycloneDX Tool Center is a community effort to establish a marketplace of free, open source, and proprietary tools and solutions that support the CycloneDX specification.
