internet of things (IoT) The internet of things refers to an insecure global network of devices connected to the internet. After three decades the familiar personal computing market had been thoroughly saturated but the internet continued to expand beyond its early scope into embedded systems typically having a single dedicated purpose, such as electricity meters, thermostats, television set-top boxes and childrens toys. The ultra low cost of many of these gadgets together with the lack of any incentive to supply them with after-market security updates meant that large parts of the IoT rapidly turned into a chaotic swamp of botnets periodically pushing out DDoS attacks against flavor-of-the-week adversaries as botmasters jockeyed for control of the networks.
