According to Ericsson, there will be 50 billion IP-connected devices by 2020, up from 1 billion
just a year ago. These are not just the omnipresent gadgets everyone is familiar with. The bulk of the
50 billion IP devices expected by later this decade will be embedded devices. These are often singlepurpose devices such as cash registers, airport check-in kiosks, medical devices, access card readers, manufacturing equipment, programmable logic controllers, industrial control systems, and much more that is now being connected.
As history has proven, security is an afterthought for most manufacturers. All these devices need proper security and management that is built in from day one. Previously, embedded devices were essentially a one-way information feed—data was sent from the device from a purely diagnostic perspective (all almost universally out-of-band), but there was no pushing of data in-band. Additionally, these devices typically did very little to influence our lives.
Now, policies and tasks can be pushed onto the device and data captured and reported back to one central console. And embedded systems have become a part of the very quality of our lives in automobile electronics, appliances, water and power systems, and the like. This phenomenon has exploded the threat scope for these devices, and security technologies, such as whitelisting and configuration control, combined with global threat intelligence gathered from millions of nodes, are becoming more than a nice to have— they are becoming a “must.” These solutions are the first step toward providing complete security on embedded systems.
