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:

// 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(

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
