πŸ” Secure Web Application Wiki

πŸš€ Overview

This project is a secure web application built using Flask that demonstrates real-world cybersecurity practices in authentication systems.

It includes multiple layers of protection such as password hashing, CSRF protection, brute-force prevention, role-based access control, and activity logging.


🎯 Objectives

  • Build a secure authentication system
  • Prevent common web attacks (CSRF, brute-force)
  • Implement role-based access control
  • Monitor and log suspicious activities
  • Apply OWASP secure coding practices

πŸ” Features

  • User Registration & Login
  • Password Hashing (Bcrypt)
  • Strong Password Validation
  • Brute-force Attack Protection
  • Role-Based Access Control (Admin/User)
  • CSRF Protection (Flask-WTF)
  • Security Logging
  • Custom Error Handling

βš™οΈ How the System Works

  1. User registers with strong password rules
  2. Password is hashed using bcrypt
  3. Login attempts are monitored and limited
  4. CSRF tokens protect form submissions
  5. Users are assigned roles (admin/user)
  6. Admin routes are restricted
  7. Activities are logged in system logs

🧠 Learning Outcomes

  • Understanding secure authentication systems
  • Implementing CSRF protection
  • Applying role-based access control
  • Preventing brute-force attacks
  • Logging and monitoring security events

πŸ› οΈ Tech Stack

  • Python (Flask)
  • SQLite Database
  • Flask-Login
  • Flask-WTF
  • SQLAlchemy
  • Bcrypt

πŸš€ Future Improvements

  • Two-Factor Authentication (2FA)
  • Admin Analytics Dashboard
  • Database-based logging system
  • IP tracking for login attempts
  • Password reset via email
  • Deployment on cloud platforms

🌍 Real-World Use Case

This project can be used as a base for:

  • Secure login systems
  • Admin dashboards
  • SaaS applications
  • Cybersecurity training environments
