## 🔒 SECURITY CONSIDERATIONS

### **1. API Authentication**

**Tambahkan API Key di Python Service:**
```python
# app.py
API_KEY = os.getenv('API_KEY', 'your-secret-key')

@app.before_request
def check_api_key():
    if request.headers.get('X-API-Key') != API_KEY:
        return jsonify({'error': 'Unauthorized'}), 401
```

**Update Laravel Service:**
```php
// FaceRecognitionService.php
$response = Http::withHeaders([
    'X-API-Key' => config('services.face_recognition.api_key')
])->post($url, $data);
```

### **2. HTTPS**

**Wajib untuk production!**

- Setup SSL di server (Let's Encrypt gratis)
- Atau pakai PaaS yang sudah include SSL (Railway, Render, dll)

### **3. Rate Limiting**

**Tambahkan di Python Service:**
```python
from flask_limiter import Limiter

limiter = Limiter(
    app,
    key_func=get_remote_address,
    default_limits=["100 per hour"]
)
```
