The Internet of Things holds incredible promise, from the cost savings afforded by facilities management sensors to the data-rich insights organizations can glean from connected devices. Even better, we’ve barely scratched the surface of what a mature, sophisticated IoT landscape will eventually look like.
But these advances often come with a risk — for now, anyway. Security has been a significant challenge for IoT devices, and we’ve already seen plenty of unfortunate cases where hackers have used connected devices to gain unauthorized network access.
Consider a food manufacturing environment, where a connected thermometer monitors temperatures in pipes or storage containers and communicates with the Wi-Fi network so it can send that data to a database. If the device is not properly secured, a hacker could interrogate the thermometer to discover credentials that enable access to the network, or even to upload instructions that would leverage the thermometer to deliver a virus.
Organizations could use blockchain to close these vulnerabilities, adding a layer of security to make IoT devices less susceptible to exploitation.
