SBOM Generation

Generate Software Bill of Materials for compliance and vulnerability management.

Overview​

A Software Bill of Materials (SBOM) is a comprehensive inventory of software components in your infrastructure. Infracast generates SBOMs from discovered hosts, enabling compliance with Executive Order 14028 and helping you understand your software supply chain.

Supported Formats​

SPDX 2.3​

The ISO/IEC 5962:2021 international standard, required for federal software procurement.

  • Industry-standard format
  • Wide tool compatibility
  • Federal compliance ready

CycloneDX 1.5​

The OWASP standard designed specifically for security use cases.

  • Rich vulnerability data
  • License compliance
  • Dependency tracking

CSV Export​

Simple spreadsheet format for custom analysis.

  • Easy to filter and sort
  • Import into existing tools
  • Quick reporting

What's Included​

SBOMs capture software inventory from discovered hosts:

  • Operating System — Name, version, kernel
  • Installed Packages — Package managers (apt, yum, pip, npm, etc.)
  • Running Services — Active software processes
  • Container Images — Docker/OCI image components

Generating SBOMs​

Per-Host SBOM​

  1. Navigate to Assets → Asset Explorer
  2. Select a host
  3. Click Generate SBOM
  4. Choose format (SPDX, CycloneDX, CSV)
  5. Download the file

Tenant-Wide SBOM​

  1. Navigate to Reports → SBOM
  2. Click Generate Tenant SBOM
  3. Choose format and options
  4. Wait for generation (may take several minutes for large environments)
  5. Download when ready

CVE Enrichment​

Infracast automatically enriches SBOMs with known vulnerabilities:

  • NVD Integration — CVE data from NIST National Vulnerability Database
  • KEV Tracking — CISA Known Exploited Vulnerabilities catalog
  • EPSS Scores — Exploit Prediction Scoring System percentiles

Vulnerable packages are flagged with:

  • CVE identifiers
  • Severity ratings (CVSS)
  • Exploitation status
  • Recommended versions

Compliance​

Executive Order 14028​

EO 14028 requires SBOMs for software sold to the federal government. Infracast helps by:

  • Generating compliant SPDX 2.3 format
  • Including required metadata fields
  • Tracking software inventory over time

FedRAMP​

Supports FedRAMP inventory requirements with:

  • Automated software discovery
  • Version tracking
  • Vulnerability correlation

CMMC​

Aligns with CMMC asset management requirements:

  • Component inventory
  • Configuration management
  • Vulnerability tracking

Best Practices​

  1. Generate Regularly — Run SBOM generation weekly or after major deployments
  2. Track Changes — Compare SBOMs over time to identify new or removed software
  3. Prioritize by Risk — Focus remediation on packages with known exploited vulnerabilities
  4. Automate — Use the API to integrate SBOM generation into your CI/CD pipeline

API Access​

Generate SBOMs programmatically:

# Generate host SBOM
POST /api/v1/tenants/{id}/sbom/generate
{
  "node_id": "aws:i-1234567890abcdef0",
  "format": "spdx"
}

# Download SBOM
GET /api/v1/tenants/{id}/sbom/{sbom_id}/download

# Application-scoped SBOM
GET /api/v1/tenants/{id}/applications/{appID}/sbom?format=spdx

# Service-level SBOM (rolled up across all member apps)
GET /api/v1/tenants/{id}/services/{serviceID}/sbom?format=cyclonedx

# CVE exposure by business service
GET /api/v1/tenants/{id}/services/{serviceID}/cve-exposure

See the API Reference for full details.

Application-Aware SBOM (Shipped 2026-04-18)​

Infrcast extends SBOM beyond per-host inventory to application and business service scopes.

Three Scopes​

ScopeAPIUse Case
HostGET /nodes/{nodeID}/sbomHost-level audits, node compliance
ApplicationGET /applications/{appID}/sbomApp security reviews, dev team SBOMs
Business ServiceGET /services/{serviceID}/sbomExecutive reporting, federal software attestation

UI View Modes​

The SBOM page exposes three views toggled from the page header:

  • Infrastructure — per-host inventory (original view)
  • Application — packages unified across all resources in a named application
  • Business Service — full service rollup with CVE exposure table

CVE Exposure by Service​

GET /api/v1/tenants/{id}/services/{serviceID}/cve-exposure

Returns a prioritized CVE list for the business service, including:

  • Package name and version
  • Affected applications and hosts
  • KEV (Known Exploited Vulnerability) flag
  • EPSS exploit probability score
  • Recommended fix version

No competitor offers service-scoped SBOM — this is a differentiated capability unique to Infracast.
