Building Vulnerability Dashboard with DefectDojo

Overview

DefectDojo is an open-source application vulnerability management platform that aggregates findings from 200+ security tools, deduplicates results, tracks remediation progress, and provides executive dashboards. It serves as a central hub for vulnerability management, integrating with CI/CD pipelines, Jira for ticketing, and Slack for notifications. DefectDojo supports OWASP-based categorization and provides REST API for automation.

When to Use

• When deploying or configuring building vulnerability dashboard with defectdojo capabilities in your environment
• When establishing security controls aligned to compliance requirements
• When building or improving security architecture for this domain
• When conducting security assessments that require this implementation

Prerequisites

• Docker and Docker Compose
• 4GB+ RAM, 2+ CPU cores, 20GB+ disk
• PostgreSQL 12+ (included in Docker deployment)
• Python 3.9+ for API integration scripts
• Jira instance (optional, for ticket integration)

Deployment

Docker Compose Deployment

# Clone DefectDojo repository
git clone https://github.com/DefectDojo/django-DefectDojo.git

# Alternative: manual Docker Compose
docker compose up -d

# Check service status
docker compose ps

# View initial admin credentials
docker compose logs initializer 2>&1 | grep "Admin password"

Organizational Structure

Hierarchy

Product Type (Business Unit)
  └── Product (Application/Service)
       └── Engagement (Assessment/Sprint)
            └── Test (Scanner Run)

Setup via API

import requests

DD_URL = "http://localhost:8080/api/v2"
API_KEY = "your_api_key_here"
HEADERS = {"Authorization": f"Token {API_KEY}", "Content-Type": "application/json"}

# Create Product Type
resp = requests.post(f"{DD_URL}/product_types/", headers=HEADERS, json={
    "name": "Web Applications",
    "description": "Customer-facing web application portfolio"
})
product_type_id = resp.json()["id"]

# Create Product
resp = requests.post(f"{DD_URL}/products/", headers=HEADERS, json={
    "name": "Customer Portal",
    "description": "Main customer-facing web application",
    "prod_type": product_type_id,
    "sla_configuration": 1,
})
product_id = resp.json()["id"]

# Create Engagement
resp = requests.post(f"{DD_URL}/engagements/", headers=HEADERS, json={
    "name": "Q1 2024 Security Assessment",
    "product": product_id,
    "target_start": "2024-01-01",
    "target_end": "2024-03-31",
    "engagement_type": "CI/CD",
    "status": "In Progress",
})
engagement_id = resp.json()["id"]

Scanner Integration

Import Scan Results via API

# Upload Nessus scan results
curl -X POST "${DD_URL}/reimport-scan/" \
  -H "Authorization: Token ${API_KEY}" \
  -F "scan_type=Nessus Scan" \
  -F "file=@nessus_report.csv" \
  -F "product_name=Customer Portal" \
  -F "engagement_name=Q1 2024 Security Assessment" \
  -F "auto_create_context=true" \
  -F "deduplication_on_engagement=true"

# Upload OWASP ZAP results
curl -X POST "${DD_URL}/reimport-scan/" \
  -H "Authorization: Token ${API_KEY}" \
  -F "scan_type=ZAP Scan" \
  -F "file=@zap_report.xml" \
  -F "product_name=Customer Portal" \
  -F "engagement_name=Q1 2024 Security Assessment" \
  -F "auto_create_context=true"

# Upload Trivy container scan
curl -X POST "${DD_URL}/reimport-scan/" \
  -H "Authorization: Token ${API_KEY}" \
  -F "scan_type=Trivy Scan" \
  -F "file=@trivy_results.json" \
  -F "product_name=Customer Portal" \
  -F "engagement_name=Q1 2024 Security Assessment" \
  -F "auto_create_context=true"

Metrics and Dashboards

Key Metrics API Queries

# Get finding counts by severity
resp = requests.get(f"{DD_URL}/findings/?limit=0&active=true",
                    headers=HEADERS)
findings = resp.json()

# Get SLA breach counts
resp = requests.get(f"{DD_URL}/findings/?limit=0&active=true&sla_breached=true",
                    headers=HEADERS)

# Get product-level metrics
resp = requests.get(f"{DD_URL}/products/{product_id}/",
                    headers=HEADERS)
