Security Implementation - Quick Deployment Guide

✅ Implementation Complete

All security features have been successfully implemented and are ready for deployment.

What Was Implemented

1. Input Validation Security ✅

• Backend: Comprehensive validation utilities and middleware
• Frontend: Real-time validation components and sanitization
• Coverage: All major routes protected (playlists, settings, channels, favorites, EPG)
• Protection: XSS, SQL injection, command injection, path traversal

2. Session Management Security ✅

• HTTP-Only Cookies: Prevents XSS access to tokens
• Secure Flags: HTTPS-only in production (SameSite=strict)
• Idle Timeout: 2-hour inactivity limit enforced
• Absolute Timeout: 24-hour maximum session lifetime
• Session API: Complete REST API for session management
• Session UI: User-friendly interface in Settings page
• Logout: Proper session cleanup and cookie clearing

Deployment Steps

1. Pre-Deployment Checklist

# ✅ Verify builds succeed
cd frontend && npm run build
cd ../backend && node -c routes/*.js

# ✅ Check Docker build (if using Docker)
docker-compose build

# ✅ Set environment variables
export JWT_SECRET="your-secure-random-string-minimum-32-chars"
export NODE_ENV="production"

2. Deploy Backend

# Copy files to production server
rsync -av backend/ production:/app/backend/

# Or if using Docker
docker-compose up -d --build

3. Deploy Frontend

# Build frontend
cd frontend && npm run build

# Copy dist folder to production
rsync -av dist/ production:/app/frontend/dist/

4. Restart Services

# If using Docker
docker-compose restart

# Or if using systemd
sudo systemctl restart streamflow-backend
sudo systemctl restart streamflow-frontend

# Or if using PM2
pm2 restart all

5. Verify Deployment

# Test backend health
curl https://your-domain.com/api/auth/security-status

# Test frontend
curl https://your-domain.com

# Check session API
curl https://your-domain.com/api/sessions/my-sessions \
  -H "Authorization: Bearer YOUR_TOKEN"

# Verify cookies (in browser DevTools)
# Should see: HttpOnly=true, Secure=true, SameSite=Strict

Environment Variables

Required

# CRITICAL: Set a strong, unique secret
JWT_SECRET=your_unique_secure_random_string_minimum_32_characters

Optional (with defaults)

# Session duration (default: 7d)
JWT_EXPIRES_IN=7d

# Environment (affects cookie security)
NODE_ENV=production

# Rate limiting (defaults shown)
RATE_LIMIT_WINDOW_MS=900000
RATE_LIMIT_MAX_REQUESTS=100

Session Configuration

Edit backend/utils/passwordPolicy.js if you want to change:

const SESSION_POLICY = {
  maxConcurrentSessions: 3,  // Change if needed
  absoluteTimeout: 24,        // Hours (change if needed)
  idleTimeout: 2,             // Hours (change if needed)
  refreshTokenRotation: true
};

Post-Deployment Testing

1. Test Login & Cookie

# Login and check response
curl -i -X POST https://your-domain.com/api/auth/login \
  -H "Content-Type: application/json" \
  -d '{"username":"test","password":"password"}'

# Look for: Set-Cookie header with HttpOnly, Secure, SameSite=Strict

2. Test Session Management

1. Login from browser
2. Navigate to Settings → Session Management
3. Verify you see your current session
4. Login from another device/browser
5. Verify you see multiple sessions
6. Try terminating a session
7. Verify terminated session gets 401 on next request

3. Test Idle Timeout

1. Login
2. Wait 2+ hours without activity
3. Make any API request
4. Should receive 401 with sessionExpired: true

4. Test Input Validation

1. Try adding a playlist with XSS: <script>alert('xss')</script>
2. Should be sanitized to: alert('xss')
3. Check security audit logs for validation events

5. Test Logout

curl -X POST https://your-domain.com/api/auth/logout \
  -H "Authorization: Bearer YOUR_TOKEN"

# Should return: {"message": "Logout successful"}
# Cookie should be cleared

Monitoring

Check Session Count

# Login to database
sqlite3 /path/to/streamflow.db

# Query active sessions
SELECT 
  u.username, 
  COUNT(s.id) as session_count 
FROM active_sessions s 
JOIN users u ON s.user_id = u.id 
GROUP BY u.id;

Check Security Audit Logs

-- Recent security events
SELECT * FROM security_audit_log 
ORDER BY created_at DESC 
LIMIT 100;

-- Failed login attempts
SELECT * FROM security_audit_log 
WHERE event_type = 'login_attempt' 
  AND status = 'failed'
ORDER BY created_at DESC;

-- Session events
SELECT * FROM security_audit_log 
WHERE event_type LIKE '%session%'
ORDER BY created_at DESC;

Rollback Plan

If issues occur:

# 1. Revert backend
git checkout HEAD~1 backend/

# 2. Revert frontend
git checkout HEAD~1 frontend/

# 3. Rebuild and restart
docker-compose up -d --build

# Or
pm2 restart all

Common Issues & Solutions

Issue: Cookies not working

Solution:

• Verify NODE_ENV=production is set
• Ensure HTTPS is enabled in production
• Check secure flag in cookie settings

Issue: Sessions expire too quickly

Solution:

• Increase SESSION_POLICY.idleTimeout in passwordPolicy.js
• Restart backend services

Issue: Users can't login

Solution:

• Check JWT_SECRET is set correctly
• Verify database has active_sessions table
• Check backend logs for errors

Issue: Frontend build fails

Solution:

• Run npm install in frontend directory
• Check for TypeScript/JSX syntax errors
• Verify all imports are correct

Issue: Rate limiting too aggressive

Solution:

• Adjust rate limits in route files
• Or set environment variables for global limits

Success Indicators

• Session UI shows active sessions
• Users can terminate sessions
• Idle timeout triggers after 2 hours
• Input validation blocks XSS/SQL injection
• Security notifications appear for blocked attacks
• Logout clears session and cookie
• Admin can view all sessions

• Backend: All route files pass syntax check
• Docker: docker-compose build succeeds

✅ No errors in logs:

• Backend logs show no errors on startup
• Frontend console shows no errors
