🚀 Quick Start

1. Add to INSTALLED_APPS

INSTALLED_APPS = [
    # Django apps
    'django.contrib.admin',
    'django.contrib.auth',
    # ...

    # Django Security Suite
    'django_security_suite',
    'django_security_suite.authentication',
    'django_security_suite.encryption',
    'django_security_suite.validation',
    'django_security_suite.audit',

    # Required dependencies
    'axes',
    'django_otp',
    'django_otp.plugins.otp_totp',
    'django_crypto_fields',
]

2. Apply Secure Defaults

# settings.py
from django_security_suite.conf import apply_secure_defaults

# Choose a risk profile: 'strict', 'moderate', or 'relaxed'
apply_secure_defaults(globals(), preset='moderate')

# Or customize specific settings
DJANGO_SEC = {
    'RISK_PROFILE': 'moderate',
    'ENABLE_RATE_LIMITING': True,
    'ENABLE_AUDIT_LOGGING': True,
    'AUTH_PROTECTION': {
        'MAX_LOGIN_ATTEMPTS': 5,
        'LOCKOUT_DURATION': 900,  # 15 minutes
    },
    'SESSION_SECURITY': {
        'ABSOLUTE_TIMEOUT': 28800,  # 8 hours
        'INACTIVITY_TIMEOUT': 3600,  # 1 hour
    },
}

3. Update Middleware

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',

    # Django Security Suite middleware
    'django_security_suite.core.middleware.SecurityHeadersMiddleware',
    'django_security_suite.core.middleware.RateLimitingMiddleware',
    'django_security_suite.authentication.middleware.SessionSecurityMiddleware',
    'django_security_suite.authentication.middleware.BruteForceProtectionMiddleware',
    'django_security_suite.audit.middleware.AuditLoggingMiddleware',

    # Rest of your middleware...
]

4. Run Migrations

python manage.py migrate

📚 Usage Examples

Encrypted Fields with Search

from django.contrib.auth.models import AbstractUser
from django_security_suite.encryption.fields import SearchableEncryptedTextField

class User(AbstractUser):
    # Searchable encrypted field
    phone_number = SearchableEncryptedTextField(max_length=20, blank=True)

    # Standard encrypted field (no search)
    ssn = models.CharField(max_length=11, blank=True)

# Query encrypted fields
users = User.objects.filter(phone_number__contains='555')  # Works!

Rate Limiting

from django_security_suite.core.decorators import rate_limit

@rate_limit(limit='10/m', key='user')
def api_endpoint(request):
    return JsonResponse({'status': 'ok'})

Input Validation

from django_security_suite.validation.serializers import SecureSerializer
from django_security_suite.validation.fields import SecureCharField, SecureEmailField

class UserSerializer(SecureSerializer):
    name = SecureCharField(max_length=100)
    email = SecureEmailField()
    bio = SecureCharField(max_length=500, sanitize_html=True)

Audit Logging

# Automatic model tracking
from django_security_suite.audit.decorators import audit_log

@audit_log(action='user.login', include_ip=True)
def login_view(request):
    # Login logic
    pass

# Query audit logs
from django_security_suite.audit.models import AuditLog

recent_logins = AuditLog.objects.filter(
    action='user.login',
    created_at__gte=timezone.now() - timedelta(hours=24)
)
