pg_tviews 0.1.0-beta.12

# Software Bill of Materials (SBOM)

**Document Version:** 1.0
**Last Updated:** 2025-12-11
**Classification:** Public
**Applicable Standards:** CycloneDX, SPDX, SLSA, ISO 27001

## Executive Summary

pg_tviews implements automated Software Bill of Materials (SBOM) generation to comply with industry supply chain security standards. SBOMs are generated in both SPDX and CycloneDX formats and are cryptographically signed for integrity verification.

## What is an SBOM?

A Software Bill of Materials (SBOM) is a formal, machine-readable inventory of software components and dependencies. It serves as a "nutrition label" for software, enabling:

- **Transparency**: Know exactly what's in your software
- **Vulnerability Management**: Quickly identify affected systems when CVEs are disclosed
- **License Compliance**: Ensure all dependencies meet legal requirements
- **Supply Chain Security**: Verify component integrity and provenance

## Regulatory Compliance

### Global Supply Chain Security Standards

pg_tviews implements comprehensive SBOM generation following industry best practices and regulatory requirements across multiple jurisdictions:

1. ✅ Provide an SBOM to customers
2. ✅ Use a standardized format (SPDX or CycloneDX)
3. ✅ Include all software components (direct and transitive dependencies)
4. ✅ Update the SBOM with each software release
5. ✅ Enable vulnerability tracking via unique identifiers

**pg_tviews Compliance Status**: ✅ **FULLY COMPLIANT**

## SBOM Format

pg_tviews generates SBOMs in **both CycloneDX 1.5 and SPDX 2.3** formats.

### Why Both Formats?

- ✅ **CycloneDX**: Security-focused, comprehensive metadata (licenses, hashes, vulnerabilities)
- ✅ **SPDX**: ISO standard, widely adopted in enterprise environments
- ✅ **Maximum Compatibility**: Support both security tools and compliance requirements

## Generating SBOMs

### Automated Generation (CI/CD)

SBOMs are automatically generated on every release via GitHub Actions:

```yaml
# .github/workflows/sbom.yml
- name: Generate SBOM
  run: ./scripts/generate-sbom.sh
```

**Artifacts Published:**
1. `pg_tviews-{version}.spdx.json` - SPDX SBOM
2. `pg_tviews-{version}.cyclonedx.json` - CycloneDX SBOM
3. `pg_tviews-{version}.sbom.txt` - Human-readable summary

### Manual Generation

#### Using Scripts

```bash
# Generate SBOM for current project
./scripts/generate-sbom.sh

# Generate for specific version
VERSION=0.1.0-beta.1 ./scripts/generate-sbom.sh
```

## Validating SBOMs

### Using CycloneDX CLI

```bash
# Install CycloneDX CLI
npm install -g @cyclonedx/cyclonedx-cli

# Validate CycloneDX format
cyclonedx validate --input-file pg_tviews-0.1.0-beta.1.cyclonedx.json
```

### Using SPDX Tools

```bash
# Install SPDX tools
pip install spdx-tools

# Validate SPDX format
pyspdxtools -i pg_tviews-0.1.0-beta.1.spdx.json
```

- `pg_tviews-{version}.sbom.txt` - Human-readable summary

Download from: https://github.com/fraiseql/pg_tviews/releases

### Verify SBOM

```bash
# Download SBOM
wget https://github.com/fraiseql/pg_tviews/releases/download/v0.1.0-beta.1/pg_tviews-0.1.0-beta.1.spdx.json

# Validate SPDX format
pyspdxtools -i pg_tviews-0.1.0-beta.1.spdx.json

# View dependencies
cat pg_tviews-0.1.0-beta.1.sbom.txt
```

## Supply Chain Security

### Dependency Verification

All dependencies are:
- ✅ Sourced from crates.io (official Rust registry)
- ✅ Version-pinned in Cargo.lock
- ✅ Audited with cargo-audit
- ✅ Scanned for vulnerabilities

### SBOM Updates

SBOM is regenerated:
- On every release
- When dependencies change
- Quarterly security reviews

## Using SBOMs for Vulnerability Management

### 1. Import into Vulnerability Scanners

```bash
# Using Grype
grype sbom:pg_tviews-0.1.0-beta.1.cyclonedx.json

# Using Trivy
trivy sbom --severity HIGH,CRITICAL pg_tviews-0.1.0-beta.1.cyclonedx.json

# Using Dependency-Track
# Upload SBOM to Dependency-Track web UI
```

### 2. Continuous Monitoring

**Automated CI/CD scanning** is performed on every release:

```yaml
# .github/workflows/sbom.yml - Automated SBOM vulnerability scanning
- name: Scan SBOM for vulnerabilities
  uses: aquasecurity/trivy-action@master
  with:
    scan-type: 'sbom'
    scan-ref: 'sbom/pg_tviews-${{ github.ref_name }}.cyclonedx.json'
    severity: 'CRITICAL,HIGH'
```

**Manual verification** can also be performed:

```bash
# Install Trivy
curl -sfL https://raw.githubusercontent.com/aquasecurity/trivy/main/contrib/install.sh | sh -s -- -b /usr/local/bin

# Scan SBOM for vulnerabilities
trivy sbom --severity HIGH,CRITICAL pg_tviews-0.1.0-beta.1.cyclonedx.json
```

### 3. Enterprise Integration

Organizations can:
1. Download SBOM from GitHub Releases
2. Import into vulnerability management systems
3. Monitor for new CVEs affecting pg_tviews dependencies
4. Receive alerts when action is required

## License Compliance

SBOMs include license information for all components, enabling:

### Automated License Scanning

```bash
# Check for copyleft licenses (GPL)
# SBOM contains license information for compliance checking
```
