About me

Hands-on experience launching and defending against real IoT attacks, and building practical security playbooks.

I am streghtening my cybersecurity journey with hands-on IoT defense experience from the Hydroficient IoT Cyber Defense externship. I learned to simulate attacks such as spoofing, replay, and unauthorized shutoffs, and to implement defenses like TLS and mTLS for connected devices.

Overview

The project worked with an IoT deployment for a marina and focused on end-to-end cyber defense: assessing device behavior, executing offensive tests, and implementing protocol-level protections. Deliverables included attack simulations and defensive configurations applied to the deployed devices.

What I've accomplished

I explored the deployed smart-device network, documented device roles and connections, and prepared the system map that guided subsequent threat analysis and attack simulations.
