Immersive Lab: IOT/Embedded Network Security & Protocols

A common security issue among IoT devices is improper use or lack of encryption and Public Key Infrastructure (PKI). Encryption of communication and authentication is needed so that adversaries cannot intercept sensitive information exchanged between devices and backend servers. It also helps prevent man-in-the-middle attacks, which impersonate backend systems and send malicious commands to affected devices.
