Demystifying SBOMs: Composition, Specifications, and SCANOSS’s Comprehensive Detection Capabilities

In today's world of software development, managing and understanding the composition of software applications is crucial for security, compliance, and efficient development processes. A Software Bill of Materials (SBOM) is a critical tool that provides detailed information about the components used in a software application, enabling developers and organizations to have a clear understanding of the open source software (OSS) used in their products. In this article, we will explore the composition of an SBOM, discuss the SPDX and CycloneDX specifications, and delve into how SCANOSS can help organizations enhance their SBOMs with comprehensive detection capabilities.

SBOM Composition

An SBOM contains detailed information about the components used in a software application, including their names, versions, licenses, and associated metadata. It provides a comprehensive list of both direct and indirect dependencies, enabling organizations to track the provenance of OSS components and assess potential security, legal, and compliance risks. By maintaining an accurate and up-to-date SBOM, organizations can proactively address potential vulnerabilities, ensure compliance with licensing requirements, and streamline their software supply chain management.

SPDX and CycloneDX Specifications

Two widely used specifications for SBOMs are the Software Package Data Exchange (SPDX) and CycloneDX. Both specifications aim to standardize the way SBOM data is represented, making it easier for organizations to exchange and process SBOM information.

The SPDX specification is an open standard created by the Linux Foundation, providing a uniform format for sharing software package metadata. It covers various aspects of software licensing, including licenses, copyrights, and security vulnerabilities. SPDX helps organizations automate the generation, exchange, and processing of SBOMs, facilitating compliance and reducing the risks associated with OSS usage.

CycloneDX, on the other hand, is a lightweight specification focused on providing a minimal and extensible SBOM format. It is designed to meet the unique needs of modern software supply chain security, enabling organizations to share and consume SBOM information more efficiently. CycloneDX emphasizes security, enabling developers to quickly identify and mitigate potential vulnerabilities in their software applications.

SCANOSS and Comprehensive Detection Capabilities

SCANOSS is an innovative OSS Inventory & Intelligence platform designed to help organizations generate and maintain accurate SBOMs, offering comprehensive detection capabilities for both declared and undeclared dependencies. With its unique ability to detect undeclared components, files, and snippets by comparing code fingerprints against the largest knowledgebase of open source, SCANOSS empowers organizations to gain a complete understanding of their software composition.

Supporting both SPDX and CycloneDX specifications, SCANOSS allows organizations to seamlessly ingest and generate SBOMs in their preferred format. This flexibility ensures that organizations can easily exchange and process SBOM information, streamlining their software supply chain management processes.

SCANOSS offers an intuitive user interface called Audit Workbench, which enables developers to generate SBOMs with ease. Additionally, the platform provides a Command Line Interface (CLI) for easy automation from other systems, allowing organizations to integrate SBOM generation into their existing workflows.


In conclusion, understanding the composition of an SBOM is crucial for effective software supply chain management, security, and compliance. By leveraging the SPDX and CycloneDX specifications and harnessing the power of SCANOSS's comprehensive detection capabilities, organizations can gain a 360-degree view of their software components and mitigate potential risks more effectively. With SCANOSS, developers can confidently produce secure and compliant code, ensuring that their applications are finished earlier, of higher quality, and with lower development costs.
