## Overview

Systematically identify security vulnerabilities in applications, dependencies, and infrastructure using automated scanning tools and manual security assessments.

## When to Use

- Pre-deployment security checks
- Continuous security monitoring
- Compliance audits (PCI-DSS, SOC 2)
- Dependency vulnerability detection
- Container security scanning
- Infrastructure security assessment

## Quick Start

Minimal working example:

```javascript
// scanner.js - Comprehensive vulnerability scanning
const { exec } = require("child_process");
const util = require("util");
const fs = require("fs").promises;

const execPromise = util.promisify(exec);

class VulnerabilityScanner {
  constructor() {
    this.results = {
      dependencies: [],
      code: [],
      docker: [],
      secrets: [],
    };
  }

  async scanDependencies() {
    console.log("Scanning dependencies with npm audit...");

    try {
      const { stdout } = await execPromise("npm audit --json");
      const auditResults = JSON.parse(stdout);

      for (const [name, advisory] of Object.entries(
// ... (see reference guides for full implementation)
```

## Best Practices

### ✅ DO

- Automate scans in CI/CD
- Scan dependencies regularly
- Use multiple scanning tools
- Set severity thresholds
- Track vulnerability trends
- Scan containers and images
- Monitor CVE databases
- Document false positives

### ❌ DON'T

- Skip vulnerability scanning
- Ignore low severity issues
- Trust single scanning tool
- Bypass security gates
- Commit secrets to repos
