Authentication

JWT Authentication

JSON Web Tokens for API authentication:

How it works:

User logs in with credentials
Server generates JWT token
Token sent to client
Client includes token in requests
Server validates token

Implementation:

// Generate token
const jwt = require('jsonwebtoken');
const token = jwt.sign(
  { userId: user.id, email: user.email },
  process.env.JWT_SECRET,
  { expiresIn: '24h' }
);

// Validate token
const decoded = jwt.verify(token, process.env.JWT_SECRET);

Best practices:

Use strong secrets (256+ bits)
Set appropriate expiration
Use HTTPS only
Store tokens securely
Rotate secrets regularly

Firebase Authentication

Google Firebase for authentication:

Features:

Email/password
Social login (Google, Facebook, etc.)
Phone authentication
Anonymous authentication
Multi-factor authentication

Implementation:

// Initialize Firebase
const firebase = require('firebase/app');
require('firebase/auth');

firebase.initializeApp({
  apiKey: process.env.FIREBASE_API_KEY,
  authDomain: process.env.FIREBASE_AUTH_DOMAIN
});

// Sign in
firebase.auth().signInWithEmailAndPassword(email, password);

Best practices:

Use Firebase security rules
Enable multi-factor authentication
Monitor authentication logs
Use strong passwords
Regular security audits

OAuth 2.0

Third-party authentication:

Supported providers:

Google
GitHub
Facebook
Twitter
Microsoft

Implementation:

// Express.js with Passport
const passport = require('passport');
const GoogleStrategy = require('passport-google-oauth20').Strategy;

passport.use(new GoogleStrategy({
  clientID: process.env.GOOGLE_CLIENT_ID,
  clientSecret: process.env.GOOGLE_CLIENT_SECRET,
  callbackURL: "/auth/google/callback"
}, (accessToken, refreshToken, profile, done) => {
  // Find or create user
  done(null, profile);
}));

Best practices:

Use HTTPS for callbacks
Validate state parameter
Store tokens securely
Request minimal scopes
Handle token expiration

Encryption

All data encrypted at rest:

What's encrypted:

Environment variables
Database data
Build artifacts
Logs
Backups

Encryption methods:

AES-256 encryption
Key management service

-- Encrypt data
INSERT INTO users (email, password)
VALUES (
  pgp_sym_encrypt('user@example.com', 'encryption_key'),
  pgp_sym_encrypt('password123', 'encryption_key')
);

Encryption in Transit

All data encrypted in transit:

HTTPS/TLS:

TLS 1.3

add_header Strict-Transport-Security "max-age=63072000" always;

Secret Management

Configuration:

{
  "resources": {
    "limits": {

      "memory": "512Mi"
    },
    "requests": {
      "cpu": "500m",
      "memory": "256Mi"
    }
  }
}

Network Isolation

Firewall Rules

Configurable firewall rules:

Default rules:

Allow HTTPS (443)
Allow HTTP (80)
Block all other inbound
Allow all outbound

Custom rules:

{
  "firewall": {
    "inbound": [
      {
        "port": 443,
        "protocol": "tcp",
        "action": "allow"
      },
      {
        "port": 80,
        "protocol": "tcp",
        "action": "allow"
      }
    ],
    "outbound": [
      {
        "port": "all",
        "protocol": "all",
        "action": "allow"
      }
    ]
  }
}

IP Whitelisting

Restrict access by IP:

Use cases:

Admin panels
Internal APIs
Development environments
Restricted content

Configuration:

{
  "ipWhitelist": [
    "192.168.1.0/24",
    "10.0.0.0/8",
    "203.0.113.50"
  ]
}

Application Security

Input Validation

Validate all user inputs:

Server-side validation:

// Express.js with Joi
const Joi = require('joi');

const schema = Joi.object({
  email: Joi.string().email().required(),
  password: Joi.string().min(8).required(),
  age: Joi.number().integer().min(18).max(120)
});

app.post('/register', (req, res) => {
  const { error } = schema.validate(req.body);
  if (error) return res.status(400).json({ error: error.details[0].message });
  // Process registration
});

Client-side validation:

// React with Formik
import { Formik, Form, Field } from 'formik';
import * as Yup from 'yup';

const validationSchema = Yup.object({
  email: Yup.string().email().required(),
  password: Yup.string().min(8).required()
});

<Formik
  validationSchema={validationSchema}
  onSubmit={handleSubmit}
>
  {/* Form fields */}
</Formik>

SQL Injection Protection

Use parameterized queries:

Safe queries:

// PostgreSQL with pg
const { Pool } = require('pg');
const pool = new Pool();

// Parameterized query
const result = await pool.query(
  'SELECT * FROM users WHERE email = $1',
  [email]
);

# Python with psycopg2
import psycopg2

conn = psycopg2.connect(DATABASE_URL)
cur = conn.cursor()

# Parameterized query
cur.execute(
  "SELECT * FROM users WHERE email = %s",
  (email,)
)

Unsafe queries (NEVER use):

// ❌ SQL injection vulnerable
const result = await pool.query(
  `SELECT * FROM users WHERE email = '${email}'`
);

XSS Protection

Prevent cross-site scripting:

Sanitize output:

// Express.js with helmet
const helmet = require('helmet');
app.use(helmet());

// Sanitize user input
const sanitizeHtml = require('sanitize-html');
const clean = sanitizeHtml(dirty);

<!-- Use text content instead of innerHTML -->
<div id="output"></div>
<script>
  document.getElementById('output').textContent = userInput;
</script>

Content Security Policy:

app.use(helmet.contentSecurityPolicy({
  directives: {
    defaultSrc: ["'self'"],
    scriptSrc: ["'self'", "'unsafe-inline'"],
    styleSrc: ["'self'", "'unsafe-inline'"],
    imgSrc: ["'self'", "data:", "https:"],
  }
}));

CSRF Protection

Prevent cross-site request forgery:

Implementation:

// Express.js with csurf
const csurf = require('csurf');
const csrfProtection = csurf({ cookie: true });

app.get('/form', csrfProtection, (req, res) => {
  res.render('form', { csrfToken: req.csrfToken() });
});

app.post('/process', csrfProtection, (req, res) => {
  // Process form
});

<!-- Include CSRF token in forms -->
<form method="POST" action="/process">
  <input type="hidden" name="_csrf" value="{{csrfToken}}">
  <!-- Form fields -->
</form>
