Opinion: If it Ain’t Broke, Try Harder

Marc Blackmer (Cisco) argues that organizations must "think like attackers" to properly secure Internet of Things devices, warning that seemingly innocuous devices (e.g., smart light bulbs) can serve as network entry points. He recommends third-party penetration testing when possible, or building in-house testing skills through staff training, red/blue exercises, capture-the-flag labs using Raspberry Pis, and familiarization with tools such as Kali Linux, Wireshark, and Shodan, while observing legal and ethical constraints.
