On disclosure, I'd `grype sbom:juice-shop.cdx.json --only-fixed` to find affected Log4j components, patch the base image, re-scan, and re-import to DefectDojo. Dedup ensures one CVE row; SLA matrix escalates Critical to 24h remediation. + +**Q2: Why didn't you use IAST/paid tools?** +Juice Shop is OSS and the course targets **repeatable, free pipelines**. Semgrep + ZAP + Trivy give 80% coverage at $0; the tradeoff is manual correlation (which we did in Lab 5) and no runtime IAST — Falco partially closes that gap at syscall level. diff --git a/submissions/lab10.md b/submissions/lab10.md new file mode 100644 index 00000000..cf21c7e1 --- /dev/null +++ b/submissions/lab10.md @@ -0,0 +1,110 @@ +# Lab 10 — Submission + +## Task 1: DefectDojo Setup + Import + +### DefectDojo version +- Version installed: **v3.1.0** (release mode) — `defectdojo/defectdojo-django:latest` via official docker-compose (`labs/lab10/work/dd`, `./docker/setEnv.sh release`) +- Admin user: `admin` (password from `docker compose logs initializer | grep -i password` — **not committed**) + +### Product + Engagement +- Product ID: **1** +- Product name: OWASP Juice Shop +- Engagement ID: **1** (`Course Semester Run`) +- Engagement status: In Progress + +### Imports completed + +| Lab | Scan type | File | Findings imported | +|-----|-----------|------|------------------:| +| 4 | Anchore Grype | `labs/lab4/grype-from-sbom.json` | 104 | +| 4 | Trivy Scan | `labs/lab4/trivy.json` | 113 | +| 5 | Semgrep JSON Report | `labs/lab5/results/semgrep.json` | 22 | +| 5 | ZAP Scan | `labs/lab5/results/auth-report.json` | **0 — failed** (DefectDojo requires XML; our ZAP output is JSON) | +| 6 | Checkov Scan | `labs/lab6/results/checkov-terraform/results_json.json` | 80 | +| 6 | KICS Scan | `labs/lab6/results/kics-ansible/results.json` | 10 | +| 7 | Trivy Scan (image) | `labs/lab7/results/trivy-image.json` | 50 | +| 7 | Trivy Operator Scan | `labs/lab7/results/trivy-k8s.json` | 0 (format mismatch — no vulnerabilities parsed) | +| 9 | Falco runtime log | `labs/lab9/falco/logs/falco.log` | skipped (no native importer — documented in runtime layer) | +| **Total raw imports** | | | **379** | +| **After dedup** | | | **331** unique non-duplicate findings | + +**Dedup enabled:** `PATCH /api/v2/system_settings/1/` → `enable_deduplication: true`, then `python manage.py dedupe --dedupe_only --dedupe_sync`. + +### Dedup example (Lecture 10 slide 11) +- **CVE/ID:** CVE-2024-37890 (`CVE-2024-37890 Ws 7.4.6`) +- **Number of source tools:** **2** — Trivy Scan (Lab 4, test 2) + Trivy Scan (Lab 7 image, test 7); same `hash_code` +- **DefectDojo canonical finding ID:** **210** (duplicate finding **375** → `duplicate_finding: 210`) + +```json +{ + "id": 375, + "title": "CVE-2024-37890 Ws 7.4.6", + "duplicate": true, + "duplicate_finding": 210, + "test": 7 +} +``` + +--- + +## Task 2: Governance Report + +### SLA matrix applied +Via API `PATCH /api/v2/sla_configurations/1/`: +- Critical: **1 day** (24 h) +- High: **7 days** +- Medium: **30 days** +- Low: **90 days** + +Product `OWASP Juice Shop` linked to SLA configuration ID 1. + +### Executive Summary (3 sentences) +OWASP Juice Shop was scanned across **7 successful tool imports** (Grype, Trivy×2, Semgrep, Checkov, KICS) into a single DefectDojo engagement.
