    Hydroficient IoT Cyber Defense Externship

    Build, hack, and defend real IoT infrastructure, then hand your security playbook to an actual company. You’ll launch realistic cyberattacks, from spoofing and replay attacks to unauthorized shutoffs, and implement defenses like TLS and mTLS.

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 bachelors degree. I have limited professional experience and Im 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

Hydroficient IoT Cyber Defense Externship

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.

Overview

The aim of the project was to respond and recover from an enterprise level simulated data breach in the cloud environment.

What I've accomplished

I identified the active vulnerabilities. Contained the threats and minimized the downtime by 50%. Isolated compromised Virtual machines

Outcome

A hardened cloud infrastracture Restored regulatory compliance by enforcing uniform bucket level access controls Restricted exposure for ports Updated security rules Post incident report
