How edge computing can help secure the IoT

Data created by Internet of Things (IoT) sensors must be secured better, say some. A simple password-on-device solution is no longer sufficient thanks to increasing data protection regulations, a new public awareness of tracking, and hugely proliferating devices. 

A new kind of architecture using Security Agents should be aggressively built into local routers and networks to handle IoT security and computation rather than offloading the number-crunching to a data center or the cloud, or indeed trying to perform it on the resource-limited IoT device, IEEE researchers say. In other words, IoT security should be handled at the network level rather than device for best results.

Boxes containing the necessary hardware could be developed specifically for the purpose, where traditional, but newly security-modified, routers aren’t applicable—such as in a smart vehicular setting, like by the side of a road.

New IoT security framework

A “new security framework is required,” say the authors of the paper, Reconfigurable Security: Edge Computing-based Framework for IoT (pdf), published by IEEE Network.

Those researchers, consisting of IEEE members and a fellow, say existing IoT security protections, which they explain generally consist of just an authenticated key exchange and access control for communications, must be upped.

“Anonymous protection and fine-grained secure access control” has to be included in the solution, they say. That includes techniques for guarding against malicious IoT devices, too.
