Projects

Secure Edge-Based IoT Gateway

Raspberry Pi, Python, MQTT, Linux

Developed an edge-based IoT security gateway using Raspberry Pi to monitor and protect connected IoT devices from network-based cyberattacks. Implemented device authentication and secure communication to prevent unauthorized devices and protect IoT data in transit. Monitored network traffic and analyzed communication patterns to detect anomalous activity and potential DoS attacks. Designed a security dashboard to visualize connected devices, detected threats, alerts, and device status.
Keylogger Detection System

Python, Cybersecurity

Developed a Python-based keylogger detection and behavioral analysis system to identify suspicious keystroke-monitoring activity while minimizing exposure of sensitive user input. Implemented a modular architecture for keystroke monitoring, activity analysis, logging, and automated report generation. Applied behavior-based analysis and statistical indicators such as typing patterns and key-usage frequency to identify potentially malicious activity. Explored persistence mechanisms and keylogging techniques in a controlled environment to understand how real-world threats operate and can be detected.
Behavioral Identity & Trust Framework for IoT Devices

Python, Machine Learning, IoT, Cybersecurity

Developed a continuous behavioral identity and trust framework for IoT devices that evaluates device behavior after authentication. Built device-specific behavioral profiles using network and operational activity to identify deviations from normal behavior. Applied machine learning to continuously adapt behavioral profiles as legitimate device behavior evolves, reducing false positives. Designed a dynamic trust mechanism that adjusts device trust levels based on detected behavioral anomalies and security events.
