Zero Trust Architecture

This implements the core building blocks of Zero Trust security: identity verification with JWT tokens, device registry tracking, continuous session monitoring, and policy-based access control. You'd reach for this when building cloud-native apps or microservices where perimeter security isn't enough, like multi-cloud deployments or remote workforce scenarios. The included gateway example and Python policy engine give you working starter code for the "never trust, always verify" model. The microsegmentation guide is especially useful if you're working with service mesh patterns. It's comprehensive but assumes you're ready to wire up your own identity provider and actually enforce these policies, this isn't a drop-in solution.

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"],
      });
