About me

Kennesaw State student leveraging strong foundational knowledge to implement IoT attack and defense techniques through Hydroficient externship.

I am a student at Kennesaw State University pursuing a bachelor's degree. I have limited professional experience and Iam building hands-on skills in IoT security through an active Hydroficient IoT Cyber Defense externship, where I test attacks and implement defenses on real devices.

Overview

The work reproduced a cloud-connected water-monitoring system, inventoried devices and telemetry flows, and applied STRIDE to enumerate spoofing, man-in-the-middle, and denial-of-service risks. Deliverables included a prioritized threat inventory with mitigation recommendations such as MFA, device certificates, and transport encryption, plus Python Colab notebooks that clean data and generate

What I've accomplished

I produced a STRIDE-based threat model that identified spoofing, MITM, and DoS risks with mitigation recommendations (MFA, device certificates, transport encryption), and I built Python Colab notebooks that clean IoT datasets and generate realistic, timestamped sensor logs.
