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.

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.
I worked through a sequence of hands-on exercises that began with system discovery and moved into threat emulation and defensive controls. Below are the specific steps I completed and the outputs I produced.
