Smart cities have been warned to revisit their operational technology (OT) security after major design flaws uncovered in machine-to-machine IoT protocols
New research has highlighted an old problem: The Internet of Things isn’t exactly secure. Hardly news, you might say, but the researchers from Trend Micro discovered that two popular IoT protocols are insecure by design. So insecure, indeed, that they are putting both ‘Industry 4.0’ smart factory implementations and smart cities at risk. In fact, these are the design flaws that could quite literally turn the lights out.
