The protection of Internet of Things devices, including sensors, cameras, industrial controllers, medical devices, and smart building systems, from cybersecurity threats. IoT security covers device authentication, firmware updates, network segmentation, data encryption, and monitoring for anomalous behavior across potentially thousands of low-power connected devices.

Why IoT Security Matters for Your Cybersecurity Career

IoT devices expand the attack surface dramatically because many ship with weak default credentials and rarely receive patches. Security engineers must segment IoT networks and monitor device behavior. Security architects design policies for IoT procurement and deployment. Healthcare and manufacturing sectors especially need IoT security expertise.
