The generated SBOM includes package names, versions, licenses, CPE identifiers, and PURL (Package URL) references.\n\n### Step 2: Parse SBOM and Extract Components\n\nParse the SBOM to extract all software components with their identifiers:\n\n**CycloneDX JSON Structure:**\n```json\n{\n  \"bomFormat\": \"CycloneDX\",\n  \"specVersion\": \"1.5\",\n  \"components\": [\n    {\n      \"type\": \"library\",\n      \"name\": \"lodash\",\n      \"version\": \"4.17.20\",\n      \"purl\": \"pkg:npm/lodash@4.17.20\",\n      \"cpe\": \"cpe:2.3:a:lodash:lodash:4.17.20:*:*:*:*:*:*:*\",\n      \"licenses\": [{\"license\": {\"id\": \"MIT\"}}]\n    }\n  ],\n  \"dependencies\": [\n    {\"ref\": \"pkg:npm/express@4.18.2\", \"dependsOn\": [\"pkg:npm/lodash@4.17.20\"]}\n  ]\n}\n```\n\n**SPDX JSON Structure:**\n```json\n{\n  \"spdxVersion\": \"SPDX-2.3\",\n  \"packages\": [\n    {\n      \"name\": \"lodash\",\n      \"versionInfo\": \"4.17.20\",\n      \"externalRefs\": [\n        {\"referenceType\": \"purl\", \"referenceLocator\": \"pkg:npm/lodash@4.17.20\"},\n        {\"referenceType\": \"cpe23Type\", \"referenceLocator\": \"cpe:2.3:a:lodash:lodash:4.17.20:*:*:*:*:*:*:*\"}\n      ],\n      \"licenseConcluded\": \"MIT\"\n    }\n  ],\n  \"relationships\": [\n    {\"spdxElementId\": \"SPDXRef-express\", \"relatedSpdxElement\": \"SPDXRef-lodash\",\n     \"relationshipType\": \"DEPENDS_ON\"}\n  ]\n}\n```\n\n### Step 3: Correlate Components with NVD CVE Database\n\nQuery the NVD 2.0 API to find known vulnerabilities for each component:\n\n```python\nimport requests\n\nNVD_API = \"https://services.nvd.nist.gov/rest/json/cves/2.0\"\n\ndef search_cves_by_cpe(cpe_name, api_key=None):\n    params = {\"cpeName\": cpe_name, \"resultsPerPage\": 50}\n    headers = {\"apiKey\": api_key} if api_key else {}\n    resp = requests.get(NVD_API, params=params, headers=headers, timeout=30)\n    resp.raise_for_status()\n    return resp.json().get(\"vulnerabilities\", [])\n\ndef search_cves_by_keyword(keyword, version=None, api_key=None):\n    params = {\"keywordSearch\": keyword, \"resultsPerPage\": 50}\n    headers = {\"apiKey\": api_key} if api_key else {}\n    resp = requests.get(NVD_API, params=params, headers=headers, timeout=30)\n    resp.raise_for_status()\n    return resp.json().get(\"vulnerabilities\", [])\n```\n\nThe NVD API supports searching by CPE name (most precise), keyword, CVE ID, and date ranges. Rate limits: 5 requests/30 seconds without API key, 50 requests/30 seconds with key.\n\n### Step 4: Build Dependency Graph and Identify Transitive Risks\n\nConstruct a directed graph of dependencies to trace vulnerability propagation:\n\n```python\nimport networkx as nx\n\ndef build_dependency_graph(sbom):\n    G = nx.DiGraph()\n    # Add nodes for each component\n    for comp in sbom[\"components\"]:\n        G.add_node(comp[\"purl\"], name=comp[\"name\"], version=comp[\"version\"])\n    # Add edges from dependency relationships\n    for dep in sbom.get(\"dependencies\", []):\n        for child in dep.get(\"dependsOn\", []):\n            G.add_edge(dep[\"ref\"], child)\n    return G\n```\n\nTransitive dependency analysis identifies components that are not directly included but are pulled in through dependency chains. A vulnerability in a deeply nested transitive dependency (e.g., 4 levels deep) still represents risk but may be harder to remediate.\n\nKey graph metrics for risk assessment:\n- **In-degree**: How many components depend on this one (high in-degree = high blast radius)\n- **Shortest path to root**: Distance from application entry point (closer = more exploitable)\n- **Betweenness centrality**: Components that sit on many dependency paths (bottleneck risk)\n\n### Step 5: Calculate Risk Scores\n\nAggregate vulnerability data into component and overall risk scores:\n\n```\nRisk Score Calculation:\n━━━━━━━━━━━━━━━━━━━━━━\nComponent Risk = max(CVSS scores of all CVEs affecting the component)\n\nWeighted Risk = Component Risk * Dependency Factor\n  where Dependency Factor = 1.0 + (0.1 * in_degree)\n  (more dependents = higher organizational impact)\n\nOverall SBOM Risk = weighted average of all component risks\n  weighted by dependency centrality\n\nRisk Levels:\n  CRITICAL: CVSS >= 9.0 or known exploited (CISA KEV)\n  HIGH:     CVSS >= 7.0\n  MEDIUM:   CVSS >= 4.0\n  LOW:      CVSS < 4.0\n```\n\n### Step 6: Cross-Validate with Grype\n\nUse grype to independently scan the SBOM and compare findings:\n\n```bash\n# Scan CycloneDX SBOM with grype\ngrype sbom:sbom-cyclonedx.json -o json > grype-results.json\n\n# Scan SPDX SBOM\ngrype sbom:sbom-spdx.json -o table\n\n# Filter by severity\ngrype sbom:sbom-cyclonedx.json --only-fixed --fail-on critical\n```\n\nGrype pulls vulnerability data from NVD, GitHub Security Advisories, Alpine SecDB, Red Hat, Debian, Ubuntu, Amazon Linux, and Oracle security databases, providing broader coverage than NVD alone.\n\n### Step 7: Generate Compliance Report\n\nProduce a structured report suitable for regulatory compliance:\n\n```\nSBOM VULNERABILITY ANALYSIS REPORT\n====================================\nSBOM File:         app-sbom-cyclonedx.json\nFormat:            CycloneDX v1.5\nAnalysis Date:     2026-03-19\nTotal Components:  247\nTotal Dependencies: 1,842 (direct: 34, transitive: 213)\n\nVULNERABILITY SUMMARY\n  Critical:  3 components / 5 CVEs\n  High:      11 components / 18 CVEs\n  Medium:    27 components / 41 CVEs\n  Low:       8 components / 12 CVEs\n\nCRITICAL FINDINGS\n1. lodash@4.17.20\n   CVE-2021-23337 (CVSS 7.2) - Command Injection via template\n   CVE-2020-28500 (CVSS 5.3) - ReDoS in trimEnd\n   Dependents: 14 components (high blast radius)\n   Fix: Upgrade to 4.17.21+\n\n2. log4j-core@2.14.1\n   CVE-2021-44228 (CVSS 10.0) - Log4Shell RCE [CISA KEV]\n   CVE-2021-45046 (CVSS 9.0) - Incomplete fix bypass\n   Dependents: 8 components\n   Fix: Upgrade to 2.17.1+\n\nDEPENDENCY GRAPH RISKS\n  Most depended-on: core-util@1.2.3 (47 dependents)\n  Deepest chain: app -> framework -> adapter -> codec -> zlib (5 levels)\n  Bottleneck components: 3 components on >50% of dependency paths\n\nLICENSE COMPLIANCE\n  Copyleft licenses found: 2 (GPL-3.0 in libxml2, AGPL-3.0 in mongodb-driver)\n  Review required for commercial distribution\n```\n\n## Key Concepts\n\n| Term | Definition |\n|------|------------|\n| **SBOM** | Software Bill of Materials; a formal inventory of all components, libraries, and dependencies in a software product |\n| **CycloneDX** | OWASP-maintained SBOM standard supporting JSON, XML, and protobuf formats with dependency graph and vulnerability data |\n| **SPDX** | Linux Foundation SBOM standard focused on license compliance with support for package, file, and snippet-level detail |\n| **PURL** | Package URL; a standardized scheme for identifying software packages across ecosystems (e.g., pkg:npm/lodash@4.17.21) |\n| **CPE** | Common Platform Enumeration; NIST naming scheme for IT products used to correlate with NVD CVE data |\n| **NVD** | National Vulnerability Database; US government repository of vulnerability data indexed by CVE identifiers |\n| **Transitive Dependency** | A dependency not directly declared but pulled in through the dependency chain of direct dependencies |\n| **CISA KEV** | CISA Known Exploited Vulnerabilities catalog; CVEs confirmed to be actively exploited in the wild |\n\n## Tools & Systems\n\n- **syft** (Anchore): Open-source SBOM generator supporting 30+ package ecosystems and CycloneDX/SPDX output\n- **grype** (Anchore): Vulnerability scanner that accepts SBOMs as input and correlates against multiple advisory databases\n- **cyclonedx-python-lib**: Python library for creating, parsing, and validating CycloneDX SBOMs programmatically\n- **lib4sbom**: Python library for parsing both SPDX and CycloneDX format SBOMs\n- **nvdlib**: Python wrapper for the NVD 2.0 API supporting CVE and CPE queries with rate limit management\n- **OWASP Dependency-Track**: Platform for continuous SBOM analysis, vulnerability tracking, and policy enforcement\n\n## Common Scenarios\n\n### Scenario: Assessing Vendor Software After Log4Shell Disclosure\n\n**Context**: After the Log4Shell (CVE-2021-44228) disclosure, the security team needs to determine which vendor-supplied applications contain vulnerable versions of log4j. Several vendors have provided SBOMs per contractual requirements.\n\n**Approach**:\n1. Collect all vendor SBOMs (CycloneDX or SPDX JSON format)\n2. Parse each SBOM and search for log4j-core components with versions < 2.17.1\n3. Query NVD API for the specific CVEs (CVE-2021-44228, CVE-2021-45046, CVE-2021-45105)\n4. Build dependency graphs to identify which application components depend on log4j\n5. Calculate blast radius: how many services and endpoints are exposed\n6. Generate prioritized remediation report sorted by exposure and business criticality\n7. Cross-validate findings with grype scan of the same SBOMs\n\n**Pitfalls**:\n- Vendor SBOMs may be incomplete, missing shaded/bundled JAR files that embed log4j\n- SPDX and CycloneDX version differences may affect parser compatibility\n- NVD API rate limits can slow analysis when scanning hundreds of components without an API key\n- CPE names in SBOMs may not exactly match NVD entries, requiring fuzzy matching\n- Transitive dependencies may include log4j even when it is not a direct dependency\n\n## Other files in this skill\n\n- [LICENSE](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/analyzing-sbom-for-supply-chain-vulnerabilities/LICENSE)\n- [references/api-reference.md](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/analyzing-sbom-for-supply-chain-vulnerabilities/references/api-reference.md)\n- [scripts/agent.py](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/analyzing-sbom-for-supply-chain-vulnerabilities/scripts/agent.py)\n\n## references/api-reference.md (verbatim)\n\n> 1 placeholder credential shortened to pass the site's secret filter.\n\n# API Reference: SBOM Supply Chain Vulnerability Analysis\n\n## NVD API 2.0 -
