# SBOM & Vulnerability Scanning Automation
2+
3+
This repository uses GitHub Actions to automatically generate a Software Bill of Materials (SBOM), scan for vulnerabilities, and produce package inventory reports.
4+
5+
All reports are named with the repository name for easy identification.
6+
7+
## Features
8+
9+
SBOM Generation: Uses Syft to generate an SPDX JSON SBOM.
10+
SBOM Merging: Merges SBOMs for multiple tools if needed.
11+
SBOM to CSV: Converts SBOM JSON to a CSV report.
12+
Vulnerability Scanning: Uses Grype to scan the SBOM for vulnerabilities and outputs a CSV report.
13+
Package Inventory: Extracts a simple package list (name, type, version) as a CSV.
14+
Artifacts: All reports are uploaded as workflow artifacts with the repository name in the filename.
15+
16+
## Workflow Overview
17+
18+
The main workflow is defined in .github/workflows/sbom.yml
19+
20+
## Scripts
21+
22+
scripts/create-sbom.sh
23+
Generates an SBOM for the repo and for specified tools, merging them as needed.
24+
scripts/update-sbom.py
25+
Merges additional SBOMs into the main SBOM.
26+
.github/scripts/sbom_json_to_csv.py
27+
Converts the SBOM JSON to a detailed CSV report.
28+
.github/scripts/grype_json_to_csv.py
29+
Converts Grype’s vulnerability scan JSON output to a CSV report.
30+
Output columns: REPO, NAME, INSTALLED, FIXED-IN, TYPE, VULNERABILITY, SEVERITY
31+
.github/scripts/sbom_packages_to_csv.py
32+
Extracts a simple package inventory from the SBOM.
33+
Output columns: name, type, version
34+
35+
## Example Reports
36+
37+
Vulnerability Report
38+
grype-report-[RepoName].csv
39+
REPO,NAME,INSTALLED,FIXED-IN,TYPE,VULNERABILITY,SEVERITY
40+
my-repo,Flask,2.1.2,,library,CVE-2022-12345,High
41+
...
42+
43+
Package Inventory
44+
sbom-packages-[RepoName].csv
45+
name,type,version
46+
Flask,library,2.1.2
47+
Jinja2,library,3.1.2
48+
...
49+
50+
## Usage
51+
52+
Push to main branch or run the workflow manually.
53+
Download artifacts from the workflow run summary.
54+
55+
## Customization
56+
57+
Add more tools to scripts/create-sbom.sh as needed.
58+
Modify scripts to adjust report formats or add more metadata.
