Implementation of an Integrated Security System for Web Attack Detection and Telegram Bot-Based SSH OTP Security

The rapid development of digital technology has brought significant benefits, including faster information dissemination and enhanced human performance. However, it has also led to a rise in cybercrime, particularly through vulnerabilities in web applications often overlooked by developers. This study presents an integrated security system combining One-Time Password (OTP) technology for Secure Shell (SSH) security and web attack detection using rule-based firewalls. Telegram is employed as a real-time notification platform to improve responsiveness. Rigorous testing using SQL injection, Cross-Site Scripting (XSS), and shell backdoor attacks demonstrates that the system effectively monitors web and server activities in real-time, promptly notifies administrators, and strengthens application security without affecting system performance.
