    'allauth.account.auth_backends.AuthenticationBackend',
]

Key Features: - Built-in User Model: Django's robust user authentication system - Django Allauth: Social authentication with GitHub integration - Session Management: Secure session handling with configurable timeouts - Password Validation: Multi-layer password strength requirements

Password Security

Password Validation Rules: 

AUTH_PASSWORD_VALIDATORS = [
    {
        'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator',
    },
    {
        'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator',
        'OPTIONS': {'min_length': 8},  # Enhanced from default 6
    },
    {
        'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator',
    },
    {
        'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator',
    },
]

Security Features: - Minimum 8 characters (enhanced from Django default) - Common password detection using extensive dictionary - User attribute similarity prevention (username, email similarity) - Numeric-only password prevention - Automatic password hashing using PBKDF2 with SHA256

Session Security

Session Configuration: 

# Session settings
SESSION_ENGINE = 'django.contrib.sessions.backends.db'
SESSION_COOKIE_AGE = 86400 * 7  # 1 week
SESSION_COOKIE_SECURE = True  # HTTPS only
SESSION_COOKIE_HTTPONLY = True  # Prevent XSS access
SESSION_COOKIE_SAMESITE = 'Lax'  # CSRF protection
SESSION_EXPIRE_AT_BROWSER_CLOSE = False
SESSION_SAVE_EVERY_REQUEST = False

Security Benefits: - Database-backed sessions for scalability and security - Secure cookie transmission (HTTPS only in production) - XSS prevention via HTTPOnly flag - CSRF protection via SameSite policy - Configurable expiration with reasonable defaults

Social Authentication (GitHub)

Django Allauth Configuration: 

# Allauth settings for secure social authentication

        self.client = openai.OpenAI(api_key=self.api_key)

    def _get_secure_api_key(self):
        # Multi-source key resolution with fallbacks
        return (
            secrets.get("OPENAI_API_KEY") or  # AWS Secrets Manager
            env.str('OPENAI_API_KEY') or      # Environment variable
            self._raise_configuration_error()
        )

        'rest_framework.throttling.UserRateThrottle'
    ],
    'DEFAULT_THROTTLE_RATES': {
        'anon': '100/day',    # Anonymous users

USER app

# Minimal package installation
RUN apt-get update && apt-get install -y \
    --no-install-recommends \
    postgresql-client \
    && rm -rf /var/lib/apt/lists/*

# Security scanning integration
LABEL security.scan="enabled"

Security Features: - Minimal base images reduce attack surface - Non-root execution prevents privilege escalation - Read-only filesystems where possible - Resource limits prevent resource exhaustion - Regular image updates and security scanning

services:
  web-prod:
    networks:
      - barody-network
    ports:
      - "80:8000"  # Minimal port exposure

    USE_HTTPS=(bool, False),
    DB_CHOICE=(str, 'postgres'),
)

# Production environment enforcement
if IS_PRODUCTION and not SECRET_KEY:
    raise ImproperlyConfigured(
        'SECRET_KEY must be set for production'
    )

Security Measures: - Secure defaults for all environment variables - Required variable validation in production - Type casting prevents injection attacks - Environment isolation between dev/staging/production

CSRF Protection

Cross-Site Request Forgery Prevention: 

# CSRF middleware (enabled by default)
MIDDLEWARE = [
    'django.middleware.csrf.CsrfViewMiddleware',
    # ... other middleware
]

# CSRF configuration
CSRF_COOKIE_SECURE = True           # HTTPS only
CSRF_COOKIE_HTTPONLY = True         # Prevent JS access
CSRF_COOKIE_SAMESITE = 'Lax'        # Cross-origin protection
CSRF_TRUSTED_ORIGINS = [            # Allowed origins
    'https://barodybroject.com',
    'https://www.barodybroject.com',
]

XSS Protection

Cross-Site Scripting Prevention: 

# Security headers
SECURE_BROWSER_XSS_FILTER = True
SECURE_CONTENT_TYPE_NOSNIFF = True

# X_FRAME_OPTIONS = 'ALLOW-FROM https://trusted-site.com'

Content Security Policy (CSP)

Recommended CSP Headers: 

# Add to middleware or web server configuration
CONTENT_SECURITY_POLICY = {
    'default-src': "'self'",
    'script-src': "'self' 'unsafe-inline' https://cdn.jsdelivr.net",
    'style-src': "'self' 'unsafe-inline' https://fonts.googleapis.com",
    'font-src': "'self' https://fonts.gstatic.com",
    'img-src': "'self' data: https:",
    'connect-src': "'self' https://api.openai.com",
}

Development Security

Secure Development Configuration: 

if DEBUG:
    # Development-specific security settings
    SECURE_SSL_REDIRECT = False      # Allow HTTP in development
    ALLOWED_HOSTS = ['localhost', '127.0.0.1', '0.0.0.0']

    # Debug toolbar (optional)
    if env.bool('ENABLE_DEBUG_TOOLBAR', default=False):
        try:
            import debug_toolbar
            INSTALLED_APPS.append('debug_toolbar')
            MIDDLEWARE.insert(0, 'debug_toolbar.middleware.DebugToolbarMiddleware')
        except ImportError:
            pass

Development Security Measures: - Environment-specific settings prevent production leaks - Debug mode controls limit exposure of sensitive data - Development tools isolation via feature flags - Local-only access for debug interfaces - Separate database instances for development

Code Security Practices

        raise ValidationError("Invalid content length")

    # Sanitize HTML content
    return bleach.clean(
        content,
        tags=ALLOWED_HTML_TAGS,
        attributes=ALLOWED_HTML_ATTRIBUTES,
        strip=True
    )

# Secure API key handling
def get_openai_client():
    """Get OpenAI client with secure key management"""
    api_key = get_secret_value('OPENAI_API_KEY')
    if not api_key:
        raise ImproperlyConfigured("OpenAI API key not configured")

    return openai.OpenAI(api_key=api_key)

Dependency Security

Package Security Management: 

# pyproject.toml - Security-focused dependencies
[tool.safety]
# Security vulnerability scanning
check = true
json = true

[tool.bandit]
# Static security analysis
exclude_dirs = ["tests", "migrations"]
skips = ["B101"]  # Skip assert_used test

[tool.ruff]
# Code quality and security linting
select = ["E", "F", "W", "C", "N", "S"]  # Include security checks

Security Practices: - Regular dependency updates with security patch priority - Vulnerability scanning with Safety and Bandit - License compliance checking - Minimal dependency principle - Pinned versions for reproducible builds

        self.get_response = get_response

    def __call__(self, request):
        # Log security-relevant requests
        if self.is_security_relevant(request):
            self.log_security_event(request)

        response = self.get_response(request)
        return response

    def log_security_event(self, request):
        logger.info(
            f"Security event: {request.method} {request.path} "
            f"from {self.get_client_ip(request)} "
            f"user: {getattr(request.user, 'username', 'anonymous')}"
        )

Security Metrics and Alerting

Key Security Metrics: - Failed login attempts per time period - API rate limit violations - Unusual access patterns detection - Error rate monitoring for potential attacks - Resource usage monitoring for DoS detection
