Describe the concept of Internet of Things (IoT) and its security implications.

The term Internet of Things (IoT) refers to the embedding of sensors in a multitude of devices (lights, heating and air conditioning, appliances, etc.) so that those devices can now connect to the Internet. The IoT has significant implications for information security. On the one hand, it makes the design of an effective set of controls much more complex. Traditionally, information security focused on controlling access to a limited number of endpoints: laptops, desktop computers, servers, printers, and mobile devices. The move to the IoT means that many other devices found in work settings now provide a potential means of accessing the corporate network and, therefore, must be secured. On the other hand, the IoT provides an opportunity to enhance physical access control.
