# Django Security Best Practices

Comprehensive security guidelines for Django applications to protect against common vulnerabilities.

## When to Activate

- Setting up Django authentication and authorization
- Implementing user permissions and roles
- Configuring production security settings
- Reviewing Django application for security issues
- Deploying Django applications to production

## Core Security Settings

### Production Settings Configuration

```python
# settings/production.py
import os

DEBUG = False  # CRITICAL: Never use True in production

ALLOWED_HOSTS = os.environ.get('ALLOWED_HOSTS', '').split(',')

# Security headers
SECURE_SSL_REDIRECT = True
SESSION_COOKIE_SECURE = True
CSRF_COOKIE_SECURE = True
SECURE_HSTS_SECONDS = 31536000  # 1 year
SECURE_HSTS_INCLUDE_SUBDOMAINS = True
SECURE_HSTS_PRELOAD = True
SECURE_CONTENT_TYPE_NOSNIFF = True
X_FRAME_OPTIONS = 'DENY'

# HTTPS and Cookies
SESSION_COOKIE_HTTPONLY = True
SESSION_COOKIE_SAMESITE = 'Lax'
CSRF_COOKIE_SAMESITE = 'Lax'

# Secret key (must be set via environment variable)
SECRET_KEY = os.environ.get('DJANGO_SECRET_KEY')
if not SECRET_KEY:
    raise ImproperlyConfigured('DJANGO_SECRET_KEY environment variable is required')

# Password validation
AUTH_PASSWORD_VALIDATORS = [
    {
        'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator',
    },
    {
        'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator',
        'OPTIONS': {
            'min_length': 12,
        }
    },
    {
        'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator',
    },
    {
        'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator',
    },
]
```

## Authentication

### Custom User Model

```python
# apps/users/models.py
from django.contrib.auth.models import AbstractUser
from django.db import models

class User(AbstractUser):
    """Custom user model for better security."""

    email = models.EmailField(unique=True)
    phone = models.CharField(max_length=20, blank=True)

    USERNAME_FIELD = 'email'  # Use email as username
    REQUIRED_FIELDS = ['username']

    class Meta:
        db_table = 'users'
        verbose_name = 'User'
        verbose_name_plural = 'Users'

    def __str__(self):
        return self.email

# settings/base.py
AUTH_USER_MODEL = 'users.User'
```

### Password Hashing

```python
# Django uses PBKDF2 by default. For stronger security:
PASSWORD_HASHERS = [
    'django.contrib.auth.hashers.Argon2PasswordHasher',
    'django.contrib.auth.hashers.PBKDF2PasswordHasher',
    'django.contrib.auth.hashers.PBKDF2SHA1PasswordHasher',
    'django.contrib.auth.hashers.BCryptSHA256PasswordHasher',
]
```

### Session Management

```python
# Session configuration
SESSION_ENGINE = 'django.contrib.sessions.backends.cache'  # Or 'db'
SESSION_CACHE_ALIAS = 'default'
SESSION_COOKIE_AGE = 3600 * 24 * 7  # 1 week
SESSION_SAVE_EVERY_REQUEST = False
SESSION_EXPIRE_AT_BROWSER_CLOSE = False  # Better UX, but less secure
```

## Authorization

### Permissions

```python
# models.py
from django.db import models
from django.contrib.auth.models import Permission

class Post(models.Model):
    title = models.CharField(max_length=200)
    content = models.TextField()
    author = models.ForeignKey(User, on_delete=models.CASCADE)

    class Meta:
        permissions = [
            ('can_publish', 'Can publish posts'),
            ('can_edit_others', 'Can edit posts of others'),
        ]

    def user_can_edit(self, user):
        """Check if user can edit this post."""
        return self.author == user or user.has_perm('app.can_edit_others')

# views.py
from django.contrib.auth.mixins import LoginRequiredMixin, PermissionRequiredMixin
from django.views.generic import UpdateView

class PostUpdateView(LoginRequiredMixin, PermissionRequiredMixin, UpdateView):
    model = Post
    permission_required = 'app.can_edit_others'
    raise_exception = True  # Return 403 instead of redirect

    def get_queryset(self):
        """Only allow users to edit their own posts."""
        return Post.objects.filter(author=self.request.user)
```

### Custom Permissions

```python
# permissions.py
from rest_framework import permissions

class IsOwnerOrReadOnly(permissions.BasePermission):
    """Allow only owners to edit objects."""

    def has_object_permission(self, request, view, obj):
        # Read permissions allowed for any request
        if request.method in permissions.SAFE_METHODS:
            return True

        # Write permissions only for owner
        return obj.author == request.user

class IsAdminOrReadOnly(permissions.BasePermission):
    """Allow admins to do anything, others read-only."""

    def has_permission(self, request, view):
        if request.method in permissions.SAFE_METHODS:
            return True
        return request.user and request.user.is_staff

class IsVerifiedUser(permissions.BasePermission):
    """Allow only verified users."""

    def has_permission(self, request, view):
        return request.user and request.user.is_authenticated and request.user.is_verified
```

### Role-Based Access Control (RBAC)

```python
# models.py
from django.contrib.auth.models import AbstractUser, Group

class User(AbstractUser):
    ROLE_CHOICES = [
        ('admin', 'Administrator'),
        ('moderator', 'Moderator'),
        ('user', 'Regular User'),
    ]
    role = models.CharField(max_length=20, choices=ROLE_CHOICES, default='user')

    def is_admin(self):
        return self.role == 'admin' or self.is_superuser

    def is_moderator(self):
        return self.role in ['admin', 'moderator']
