    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.

Overview

The externship exercised offensive and defensive techniques against an operational IoT deployment for a marina. The work inspected device interactions, attack surfaces, and network flows, then progressed to hands-on exploitation and implementation of protocol-level defenses. Deliverables documented vulnerabilities and recommended technical mitigations.

What I've accomplished

I mapped the Grand Marina IoT system, identified attacker paths, applied STRIDE to prioritize threats, and delivered a consolidated threat model PDF plus a visual threat card outlining key vulnerabilities.
