Securing The 'Internet of Things'
Once upon a time the Internet was all about connecting people via their computers. Then along came mobile which allowed people to connect while on the move. But as more and simpler devices are coming equipped with an IP connection, the people have largely left the room leaving all sorts of devices talking directly to each other and to higher systems via the web, without human intervention or supervision.
Predictions say that by 2020 some 30 to 50 billion ‘things’ will be connected to the internet, from simple widgets like temperature sensors and domestic water meters, to more critical devices such as power plant telemetry and ATMs. The security implications are obvious but cannot be assumed to have been addressed, which raises some key questions we need to discuss.
