# Best Practices: SBOM for AI (Software Bill of Materials for Artificial Intelligence)
## Overview
These practices address the critical need for transparency and traceability in AI supply chains. Unlike traditional software, AI systems involve unique components—such as datasets, models, and specialized infrastructure—that introduce complex security risks. Implementing an "SBOM for AI" allows organizations to track vulnerabilities, manage dependencies, and improve cybersecurity resilience across the AI lifecycle.
## Key Recommendations
### Immediate Actions
1. **Inventory AI Use Cases:** Map all AI systems currently deployed or under development within the organization.
2. **Adopt the Seven Cluster Framework:** Begin organizing AI asset documentation into the G7-defined clusters: **Metadata, Models, Dataset Properties (DP), System Level Properties (SLP), Key Performance Indicators (KPI), Security Properties (SP), and Infrastructure.**
3. **Establish Metadata Baselines:** Ensure every AI component has associated metadata (the SBOM for AI itself) to allow for basic identification and ownership tracking.
### Short-term Improvements (1-3 months)
1. **Define Model & Dataset Properties:** Document model architecture, training data sources (Dataset Properties), and intended use cases to identify potential biases or data poisoning risks.
2. **Integrate Security Properties (SP):** Record security-specific attributes such as encryption status, access controls, and known vulnerabilities associated with AI libraries.
3. **Collaborate with Vendors:** Request SBOMs for AI from third-party AI service providers and software vendors to ensure visibility into external dependencies.
### Long-term Strategy (3+ months)
1. **Automate SBOM Generation:** Integrate SBOM creation tools into the CI/CD pipeline for AI models to ensure documentation remains current as models are retrained.
2. **Establish Lifecycle Governance:** Link SBOM data to the organization’s vulnerability management and incident response programs to react swiftly to newly discovered AI-specific exploits.
3. **Monitor Performance Drift:** Use the KPI cluster within the SBOM to track model degradation or performance shifts that may indicate security tampering or environmental changes.
## Implementation Guidance
### For Small Organizations
- **Focus on High-Risk Assets:** Prioritize generating SBOMs for AI systems that handle sensitive customer data or critical business logic.
- **Utilize Open Standards:** Leverage existing SBOM formats (like CycloneDX or SPDX) that are expanding to support AI.
### For Medium Organizations
- **Standardize Documentation:** Implement a centralized repository for all AI SBOMs to ensure consistency across different departments.
- **Risk Assessment:** Use SBOM data to perform periodic supply chain risk assessments, focusing on the reputation and security posture of model/data providers.
### For Large Enterprises
- **Inter-Departmental Alignment:** Foster collaboration between IT, Security, and Data Science teams to ensure the "Model" and "Dataset" clusters are accurately populated.
- **Supply Chain Enforcement:** Make the provision of a comprehensive SBOM for AI a mandatory requirement in procurement contracts for all AI-related vendors.
## Configuration Examples
While specific technical code was not provided in the guidance summary, the framework suggests the following structured record format for an AI SBOM:
* **Cluster: Metadata** -> `SBOM_ID`, `Author`, `Timestamp`, `Tool_Used`
* **Cluster: Models** -> `Model_Type`, `Version`, `Weights_Checksum`, `Architecture_Details`
* **Cluster: Dataset Properties** -> `Data_Source`, `Data_Size`, `Sourcing_Date`, `Licensing`
* **Cluster: Security Properties** -> `Vulnerability_Scans`, `Encryption_Algorithm`, `Adversarial_Robustness_Scores`
## Compliance Alignment
- **G7 AI Guidelines:** Aligns with the G7 Cybersecurity Working Group’s shared vision for AI transparency.
- **CISA Secure-by-Design:** Supports the initiative to build security into the foundation of software and AI.
- **NIST AI Risk Management Framework (RMF):** Complements NIST standards by providing the technical documentation needed for risk mapping.
## Common Pitfalls to Avoid
- **Treating AI like Standard Software:** Failing to document datasets and model weights (which are not captured in traditional SBOMs).
- **Static Documentation:** Treating the SBOM as a one-time document rather than a "living" record that changes as models are updated or retrained.
- **Data Silos:** Keeping SBOM information within the development team and not sharing it with the security operations center (SOC).
