Build a Secure Online Banking Simulation
Create a simulation of a secure online banking platform that includes encrypted login, transaction validation, and protections against phishing, CSRF, and session hijacking — perfect for cybersecurity practice.Banking systems are top targets for cybercriminals. This project simulates secure components of an online banking environment to test encryption, session management, multi-factor authentication, and secure transaction handling — all without real money risk.
The app simulates customer registration, login with MFA, balance checks, fund transfers, transaction history, and logout — all secured with HTTPS, input validation, CSRF tokens, and encryption standards used in real-world banking platforms.
Encrypted Login with MFA
Secure user authentication with password hashing, OTP via email/SMS, and HTTPS transport.
Secure Fund Transfer
Implement transactional integrity with input validation, CSRF protection, and request authorization.
Session Management & Timeout
Use secure cookies, token validation, and idle timeout to prevent session hijacking.
Transaction History & Alerts
Store and display transaction logs with simulated notifications for large/suspicious activity.
Users register and log in securely. Upon login, they can view their balance, send funds, or review their transactions. Behind the scenes, the system uses encryption, token validation, and session tracking to prevent typical web-based attacks.
- User registers with encrypted credentials and MFA setup.
- Secure login flow with OTP or TOTP token verification.
- All requests validated against CSRF tokens and session cookies.
- Transactions processed after confirming input and session validity.
- System logs all user activity and alerts on anomalies.
Backend & Security
Flask/Django with bcrypt for hashing, pyotp for 2FA, Flask-Login for session security.
Frontend
React.js or HTML/CSS with secure form handling and client-side input validation.
Database
PostgreSQL or SQLite with transaction logging and secure user record storage.
Additional Security
HTTPS, CSRF tokens, secure cookies, Helmet.js (if Node), and TLS certificates (Let's Encrypt).
1. Build Secure Registration & Login
Hash passwords, send OTP via email/SMS, and implement secure sessions with tokens.
2. Create Fund Transfer Module
Add secure money transfer form with CSRF protection and amount validation.
3. Implement Session Security
Configure secure cookies, enforce HTTPS, and auto-logout on inactivity or browser close.
4. Add Logs and Alerts
Store transaction logs and notify the user of large or unusual activities.
5. Deploy with HTTPS
Use self-signed or Let's Encrypt certificates for simulating real banking encryption.
Simulate and Secure Financial Transactions
Learn real-world banking security practices by building a secure simulation — practice safe session handling, encrypted transactions, and multi-factor authentication.
