Overview

Implement comprehensive Zero Trust security architecture based on "never trust, always verify" principle with identity-centric security, microsegmentation, and continuous verification.

When to Use

• Cloud-native applications
• Microservices architecture
• Remote workforce security
• API security
• Multi-cloud deployments
• Legacy modernization
• Compliance requirements

Quick Start

Minimal working example:

// zero-trust-gateway.js
const jwt = require("jsonwebtoken");
const axios = require("axios");

class ZeroTrustGateway {
  constructor() {
    this.identityProvider = process.env.IDENTITY_PROVIDER_URL;
    this.deviceRegistry = new Map();
    this.sessionContext = new Map();
  }

  /**
   * Verify identity - Who are you?
   */
  async verifyIdentity(token) {
    try {
      // Verify JWT token
      const decoded = jwt.verify(token, process.env.JWT_PUBLIC_KEY, {
        algorithms: ["RS256"],
      });

      // Check token hasn't been revoked
      const revoked = await this.checkTokenRevocation(decoded.jti);
      if (revoked) {
        throw new Error("Token has been revoked");
// ... (see reference guides for full implementation)

Best Practices

✅ DO

• Verify every request
• Implement MFA everywhere
• Use microsegmentation
• Monitor continuously
• Encrypt all communications
• Implement least privilege
• Log all access
• Regular audits

❌ DON'T

• Trust network location
• Use implicit trust
• Skip device verification
• Allow lateral movement
• Use static credentials
