CISA and partner agencies in the United States and 13 allied countries released updated guidance for the minimum elements of a Software Bill of Materials, replacing the 2021 NTIA baseline with broader requirements intended to improve software transparency and supply chain risk management. The revised framework preserves the original core principles but adds fields for component hash information, license data, author or digital signature, SBOM version, data format details, generation context, and tool metadata, while removing elements such as Access Control and SWID Tags. Officials said the changes were shaped by software supply chain security developments and feedback gathered during a 2025 public comment period.
The update is designed to make SBOMs more useful for automated vulnerability management and procurement decisions, and it explicitly notes that some software categories need additional treatment beyond the general baseline. In parallel, the G7 Cybersecurity Working Group published guidance on the minimum elements for an AI-focused SBOM, providing actionable recommendations for public- and private-sector stakeholders to improve transparency across the AI supply chain. The combined guidance signals a broader international push to standardize software component disclosure for both conventional software and AI systems, with future work expected on SaaS, AI-specific components, SBOM trustworthiness, and links to formats such as VEX and CSAF.

6 events from the most recent confirmed update back to the earliest known activity.
A day after the updated SBOM guidance, CISA issued separate guidance on open source software security for government agencies. The guidance encouraged a default-open-source approach for government-developed software and called for transparency into AI-related components, including model training data.
Government agencies in the United States and 13 allied countries released updated guidance on SBOM minimum elements, replacing the 2021 baseline and adding fields such as component hashes, license data, generation context, tool metadata, and SBOM version.
A paper produced by the G7 Cybersecurity Working Group set out actionable guidance on the minimum elements an AI SBOM should contain for public and private sector stakeholders.
The G7 introduced a shared vision for AI software bills of materials, providing the basis for later guidance on minimum AI SBOM elements.
Feedback gathered during a 2025 public comment period was incorporated into the revised SBOM minimum elements guidance.
The 2026 SBOM guidance replaces the 2021 NTIA SBOM Minimum Elements guidance, which established the original baseline framework for software bill of materials content.
