🔐 Security

Implemented Security Features:

✅ Authentication:

• bcrypt password hashing (10 salt rounds)
• JWT tokens (httpOnly cookies in production)
• Protected routes with auth middleware
• Email verification required

✅ Input Validation:

• express-validator for all inputs
• Custom validators for URLs (domain checking)
• SQL injection prevention (Prisma parameterized queries)
• XSS protection (input sanitization)

✅ Rate Limiting:

• Login attempts: 5 per 15 minutes
• Registration: 3 per hour
• Email sending: 3 per hour

✅ Database:

• Unique constraints on emails, usernames
• Indexed fields for performance
• Cascading deletes for data integrity

✅ Event Security:

• Unique alphanumeric slugs (12 chars, MD5-based)
• Prevents ID enumeration attacks
• URLs: /events/{slug}/chat instead of /events/{id}/chat

✅ Socket.IO:

• JWT authentication for WebSocket connections
• Room-based access control
• User verification before joining rooms

Planned Security Features (Phase 3):

⏳ CORS configuration ⏳ CSRF protection (cookies) ⏳ Helmet.js security headers ⏳ Content Security Policy ⏳ HTTPS enforcement (production)
