CycloneDX BOM Standard

CycloneDX is a modern standard for the software supply chain. SBOM, SaaSBOM, CBOM, OBOM, VEX, and more. CycloneDX is a OWASP project ratified as ECMA-424

Welcome to the CycloneDX Community

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)

The CycloneDX project provides standards in XML, JSON, and Protocol Buffers, as well as a large collection of official and community supported tools that create or interoperate with the standard.

The project's website has many documented use cases and examples that provide a springboard to SBOM adoption.

The project operates as a meritocracy whose guiding principles reinforce its risk-based approach to standards development. The project encourages community participation in the development of the standard and supporting tools.

Background

Modern software is assembled using third-party and open source components. They are 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.
