An anonymous reader writes "Gartner reckons that the number of connected devices will hit 26 billion by 2020, almost 30 times the number of devices connected to the IoT in 2009. This estimate doesn't even include connected PCs, tablets and smartphones. The IoT will represent the biggest change to our relationship with the Internet since its inception. Many IoT devices themselves suffer from security limitations as a result of their minimal computing capabilities. For instance, the majority don't support sufficiently robust mechanisms for authentication, leaving network admins with only weak alternatives or sometimes no alternatives at all. As a result, it can be difficult for organizations to provide secure network access for certain IoT devices."
