The Internet of Things, or IoT, describes the part of the electronic universe that comprises network-attached appliances and embedded devices. These may include "smart home" devices and controls, "smart appliances" for performing common home or office tasks, "smart speakers" or other authentication-free forms of leisure computing, and similar devices. IoT devices represent a relatively new security concern whose implications are still unclear.¶Particularly worrying is the fact that most IoT devices are either secured and authenticated only during initial configuration and rarely after that, or not substantively authenticated at all, leaving them potentially open to various attacks and forms of illicit misuse. This is particularly concerning because both industrial manufacturing and critical infrastructure often rely on IoT devices for monitoring and safety.
