Interesting Article on Device Level Security

As the security of individual field devices (sensors, transmitters, acuators, etc.) is often overlooked, these devices can provide a target for cyber attacks. This article by Matt Luallen of Control Engineering explains this fact in more detail – once again reminding us that security of such devices should not be taken lightly. Luallen states that “If your technicians can configure a field device through the control system, dedicated handheld tools, or by plugging in a laptop to the network, an attacker can do the same thing if he follows the right path.”

Secure communication is an important building block of device security. The wolfSSL embedded SSL library has been designed for resource-constrained embedded systems and can easily be added to your device.
