Overview
The work examined an operational smart-building IoT deployment and then simulated attacks and defenses against its devices. The project mapped device roles and network relationships, identified attack surfaces, and executed exploit scenarios such as spoofing and replay; the work also implemented cryptographic protections including TLS and mTLS.
What I've accomplished
I explored the deployed smart-building system to establish a baseline understanding of its devices and network topology before conducting threat analysis and defensive implementations.
