Building Vulnerability Dashboard With Defectdojo

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

Common Misconfigurations & Verification

• Deduplication misconfigured — the same finding counted across tools inflates totals. Verify deduplication_on_engagement and the dedupe algorithm per parser.
• Wrong scan_type on import — a parser mismatch drops or mangles findings. Verify imported counts match the source report.
• auto_create_context sprawl — verify products/engagements aren't duplicated by typos in names.
• SLA config not attached to product — verify each product has an sla_configuration so breach metrics compute.
• Jira severity mapping — verify critical→Blocker mapping and that closing a Jira issue syncs finding status.
• Reimport vs import — verify you use reimport so re-scans update existing findings instead of creating duplicates.

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)

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",
