Protecting IoT devices from cyberattacks: A critical missing piece
When it comes to protecting IoT devices from cyber attacks, both device hardening and security appliance approaches each has its supporters, but there are trade-offs between “device-centric” and “appliance-centric.”

Building security into the device

One approach to IoT security is to build protection directly into the device. This provides a critical security layer—the devices are no longer dependent on the corporate firewall as their sole protection. This is especially critical for mobile devices and IoT endpoints deployed in remote locations.

A security solution for IoT devices must provide protection against a wide range of cyber attacks. It must ensure the device firmware has not been tampered with, be able to secure the data stored by the device, secure in and outbound communications, and it must detect and report attempted cyber attacks. This can only be achieved by including security in the early stages of design.

While there is no one-size-fits-all security solution for embedded devices, solutions are available that provide a framework for OEMs. A security framework provides OEMs with the core capabilities required to protect their devices and the flexibility needed to customize the solution to the specific requirements of their device, while ensuring that critical security capabilities are included.
