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 a simulated IoT deployment for a marina environment. The work catalogued device interactions, attack surfaces, and implemented standard controls such as TLS and mTLS where applicable. Deliverables included an adversary-style assessment and a security playbook of recommended mitigations.
I worked through a hands-on sequence: first mapping the system, then enumerating vulnerabilities, executing attacks, and finally implementing network and device-level defenses and documentation.
