The Internet of Things (IoT) is transforming our homes, businesses and public spaces – mostly for the better – but without proper precautions IoT devices can be an attractive target for malicious actors and cyberattacks. Security threats involving IoT devices often stem from the fact that many IoT devices usually have single-purpose designs and may lack broader capabilities to defend themselves in a hostile environment. For example, a door bell, a toaster or a washing machine frequently do not contain as much storage, memory and processing capability as a typical laptop computer.
