Encryption In Automation

Posted by Matt Newton on Apr 11, 2017 2:51:12 PM

As the IIoT continues its widespread adoption, a lot of new IT technologies are quickly being adopted by the industrial automation and process control industries. More and more, industrial assets are becoming Internet enabled and being connected to other digital systems.

Monitoring OEE and KPIs in real time from a mobile device is no longer a pie-in-the-sky application. It’s happening right now, through the convergence of OT and IT.

One of the technologies that’s enabling the IIoT is secure digital communication. And to establish that secure communication, you need to have an authority you can trust that can validate the indentity of devices on a network and on the Internet. You have to trust that the encrypted connection you're using is actually connected to the device you want to talk to, and not to some rogue node trying to breach your network and steal your information.

That’s where Certificate Authorities come into play in the IIoT.

Automation 101: Adding Control to AC Motors

Posted by Matt Newton on Mar 30, 2017 9:01:33 AM

In one of our previous blog posts we talked about AC motors, the workhorse of modern industrial automation. We learned how they use magnets, electromagnets, and magnetic fields to generate huge amounts of torque to run our industrial processes.

To understand how modern motor control works, let’s take a closer look at how a 3-phase AC induction motor works.

Social Engineering: Your automation network's largest security vulnerability

Posted by Matt Newton on Mar 21, 2017 8:00:00 AM


When most people think about cyber security, they probably conjure up thoughts of someone locked away in a dark room, wearing the same grey hoodie for months. Staring at a screen for days at a time looking for just the right network packet to tell them where and how to attack. But that's not always how hacking is done.
