I wanted to understand how real-world web applications implement security mechanisms beyond basic login systems, especially focusing on authentication security and attack prevention techniques.
It’s like a building:
- Password = your key
- Bcrypt = key is encrypted
- Brute-force protection = security guard blocking repeated attempts
- CSRF = prevents fake entry requests
- Roles = admin has master access, users have limited access
- Logs = CCTV recording everything
- Flask (Backend)
- SQLite (Database)
- Flask-Login (Authentication)
- Flask-WTF (Form Security)
- Bcrypt (Password Hashing)
I developed a secure web application using Flask that implements user authentication with multiple security features such as password hashing using bcrypt, CSRF protection, brute-force attack mitigation, and role-based access control. The system also includes security logging to track login attempts and suspicious activities, aligning with secure coding practices and OWASP guidelines.
This project is a secure authentication-based web application where users can register and log in. I implemented strong password validation and hashing using bcrypt to ensure credential security.
I added brute-force protection by limiting login attempts per IP, and CSRF protection using Flask-WTF to prevent unauthorized form submissions.
The application also includes role-based access control, where admin users can access restricted routes. Additionally, I implemented logging to track events such as failed logins and suspicious activity, which is important for security monitoring and incident response.
I made a secure login system like the ones you see on websites, but with extra protection. It checks if your password is strong, stores it safely (not in plain text), blocks too many wrong login attempts, and even keeps track of suspicious activity. It also has admin and normal user roles, so some pages are restricted.
