If you're contributing to Smart Quiz System, please follow these security guidelines:

• Always validate user input on both client and server side
• Use Django's built-in form validation
• Sanitize HTML input using libraries like bleach
• Validate file uploads and limit file types

• Never store passwords in plain text
• Use Django's built-in authentication when possible
• Implement proper session management
• Follow the principle of least privilege

• Use Django ORM to prevent SQL injection
• Never include sensitive data in version control
• Use parameterized queries for any raw SQL
• Implement proper database access controls

• Implement rate limiting on all endpoints
• Use HTTPS in production
• Validate all API inputs
• Implement proper error handling that doesn't leak information

# Use strong secret keys
SECRET_KEY=your-complex-secret-key-here

# Disable debug in production
DEBUG=False

# Configure allowed hosts
ALLOWED_HOSTS=yourdomain.com,www.yourdomain.com

# Use secure database connections
DATABASE_SSL_REQUIRE=True

# Django settings for production
SECURE_BROWSER_XSS_FILTER = True
SECURE_CONTENT_TYPE_NOSNIFF = True
SECURE_HSTS_SECONDS = 31536000
SECURE_HSTS_INCLUDE_SUBDOMAINS = True
SECURE_HSTS_PRELOAD = True
SECURE_SSL_REDIRECT = True
SESSION_COOKIE_SECURE = True
CSRF_COOKIE_SECURE = True

• Keep all dependencies up to date
• Monitor for security advisories
• Apply security patches promptly
• Regular security audits

1. Cross-Site Scripting (XSS)

   • All user input is escaped by default in Django templates
   • TailwindCSS classes prevent most XSS vectors
   • Content Security Policy headers implemented

2. Cross-Site Request Forgery (CSRF)

   • Django CSRF protection enabled
   • CSRF tokens required for all state-changing operations
   • SameSite cookie attributes configured

3. SQL Injection

   • Django ORM used exclusively for database operations
   • No raw SQL queries without parameterization
   • Database user has minimal required permissions

4. Authentication & Session Management

   • JWT tokens with appropriate expiration
   • Secure session cookie configuration
   • Password hashing using PBKDF2

1. Rate Limiting

   • Implement rate limiting on login attempts
   • Add API rate limiting for quiz submissions
   • Consider implementing CAPTCHA for repeated failures

2. File Upload Security

   • Implement virus scanning for uploaded files
   • Restrict file types and sizes
   • Store uploads outside web root

3. Audit Logging

   • Log all authentication attempts
   • Log administrative actions
   • Monitor for suspicious patterns

We recommend the following security testing practices:

# Security dependency check
safety check

# OWASP ZAP scanning
docker run -v $(pwd):/zap/wrk/:rw -t owasp/zap2docker-stable zap-baseline.py -t http://localhost:8000

# Bandit security linter for Python
bandit -r backend/

• Authentication bypass attempts
• Authorization checks for all endpoints
• Input validation testing
• Session management testing
• HTTPS configuration verification
