Vulnerability Management with DefectDojo

Overview

DefectDojo aggregates findings from every SecOpsAgentKit scanner into one platform—deduplicating across tools, tracking SLA compliance, and producing compliance-ready reports. It transforms isolated scanner outputs into a managed vulnerability backlog with ownership and remediation history.

Key concepts:

  • Product: An application or system being tracked
  • Engagement: A time-boxed security activity (sprint, assessment, CI/CD pipeline)
  • Test: A scanner run within an engagement
  • Finding: A deduplicated security issue with full lifecycle (Active → Mitigated → Closed)

Quick Start

Start DefectDojo locally:

git clone https://github.com/DefectDojo/django-DefectDojo.git
cd django-DefectDojo && docker compose up -d
# Access at http://localhost:8080 — change admin/admin password immediately

Import the first scan result:

pip install requests
./scripts/import_findings.py \
  --host http://localhost:8080 \
  --api-key <your-api-key> \
  --engagement-id 1 \
  --scan-type "Semgrep JSON Report" \
  semgrep-results.json

Retrieve your API key: DefectDojo UI → User (top-right) → API v2 Key.

Core Workflow

1. Setup: Products and Engagements

Create a Product (once per application) and an Engagement (once per sprint or pipeline):

# Create product
curl -s -X POST "$DD_HOST/api/v2/products/" \
  -H "Authorization: Token $DD_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"name": "My App", "description": "Main application", "prod_type": 1}'

# Create engagement — use template for full options
curl -s -X POST "$DD_HOST/api/v2/engagements/" \
  -H "Authorization: Token $DD_API_KEY" \
  -H "Content-Type: application/json" \
  -d @assets/defectdojo-engagement-template.json

See assets/defectdojo-engagement-template.json for a full CI/CD engagement template.

2. Import Scanner Findings

# Semgrep (SAST)
./scripts/import_findings.py --host $DD_HOST --api-key $DD_API_KEY \
  --engagement-id $EID --scan-type "Semgrep JSON Report" semgrep.json

# Trivy (containers/filesystem)
./scripts/import_findings.py --host $DD_HOST --api-key $DD_API_KEY \
  --engagement-id $EID --scan-type "Trivy Scan" trivy.json

# Gitleaks (secrets)
./scripts/import_findings.py --host $DD_HOST --api-key $DD_API_KEY \
  --engagement-id $EID --scan-type "Gitleaks Scan" gitleaks.json

# Re-import after fixes — auto-closes resolved findings
./scripts/import_findings.py --reimport --host $DD_HOST --api-key $DD_API_KEY \
  --engagement-id $EID --scan-type "Trivy Scan" trivy-new.json

For the complete mapping of every SecOpsAgentKit tool to its DefectDojo parser name and required output format, see references/tool-parser-map.md.

3. CI/CD Pipeline Integration

Add an import step after each scanner in any pipeline:

# GitHub Actions — add after each scanner step
- name: Import findings to DefectDojo
  env:
    DD_HOST: ${{ secrets.DD_HOST }}
    DD_API_KEY: ${{ secrets.DD_API_KEY }}
    DD_ENGAGEMENT_ID: ${{ secrets.DD_ENGAGEMENT_ID }}
  run: |
    pip install requests
    ./scripts/import_findings.py \
      --host "$DD_HOST" \
      --api-key "$DD_API_KEY" \
      --engagement-id "$DD_ENGAGEMENT_ID" \
      --scan-type "Semgrep JSON Report" \
      semgrep-results.json

4. Full Aggregation Workflow

Progress: [ ] 1. Run all applicable scanners; save JSON output for each [ ] 2. Import each result file with correct --scan-type (see references/tool-parser-map.md) [ ] 3. Review deduplicated findings in DefectDojo UI: Engagements → Tests → Findings [ ] 4. Triage: set severity, assign owner, and set SLA due dates [ ] 5. Risk-accept findings with business justification (required for SOC2/PCI-DSS evidence) [ ] 6. Re-run scanners after fixes; --reimport to auto-close resolved findings [ ] 7. Export compliance report: Reports → Generate Report

Work through each step systematically. Check off completed items.

5. Triage and Prioritization

After import in the DefectDojo UI:

  1. Filter by severity: Critical → High → Medium
  2. Verify deduplication: DefectDojo auto-deduplicates across scans. Review grouped duplicates before accepting.
  3. Assign findings to engineers with SLA due dates
  4. Risk Accept: Document business justification for accepted risks
  5. Tag findings by component or compliance requirement (e.g., pci-req-6.3)

Security Considerations

  • Sensitive Data Handling: DefectDojo stores vulnerability details that reveal application internals. Restrict access by role. Enable HTTPS and use SSO/LDAP for authentication in production.
  • Access Control: Issue separate API keys per pipeline with minimum importer role. Use security lead role for triage operations. Rotate keys quarterly.
  • Audit Logging: DefectDojo logs all finding status changes. Export audit logs as SOC2 CC7.1 and PCI-DSS 6.3.3 compliance evidence.
  • Compliance: SLA tracking and risk acceptance workflows directly satisfy SOC2, PCI-DSS, and GDPR vulnerability management requirements. Tag findings with compliance controls for filtered audit exports.
  • Safe Defaults: Enable 2FA, change default admin/admin credentials immediately, enable HTTPS via the override compose file (docker-compose.override.https.yml).

Common Patterns

Pattern 1: Continuous CI/CD Engagement

Create one persistent CI/CD engagement per branch. Re-import on every merge to keep a live deduplicated finding list with auto-closure of fixed issues.

Pattern 2: Sprint Security Review

Import all scanner outputs at end of sprint into a single time-boxed engagement. Review combined risk posture in one place; assign findings to the next sprint backlog.

Pattern 3: Compliance Audit Export

Before an audit, filter findings by compliance tag (e.g., pci-dss), include risk acceptances and closure timestamps. Export as the vulnerability management evidence package.

Integration Points

  • All SecOpsAgentKit scanners: Parser names mapped in references/tool-parser-map.md
  • CI/CD: GitHub Actions, GitLab CI, Jenkins, CircleCI — add import step after each scanner
  • Issue Trackers: DefectDojo pushes findings to JIRA, GitHub Issues via built-in integrations
  • Notifications: Slack and email alerts for new Critical/High findings via DefectDojo notification rules
  • SIEM: Export findings as JSON for ingestion into Splunk, Elastic, or other SIEM platforms

Troubleshooting

Issue: 403 Forbidden on import

Solution: Verify the API key has importer role or higher. Regenerate at User → API v2 Key. Confirm --host does not include a trailing slash.

Issue: Duplicate findings after re-import

Solution: Use --reimport (not a second --import) for subsequent scans of the same tool against the same engagement. Re-import updates existing findings instead of creating new ones.

Issue: Scan type not recognized

Solution: Parser names are case-sensitive. Check the exact value in references/tool-parser-map.md. Use curl "$DD_HOST/api/v2/importers/" -H "Authorization: Token $DD_API_KEY" to list all available parsers.
