groov EPIC Security Series, Part 5: Encryption and Certificates

Posted by Ben Orchard on May 22, 2019 11:05:13 AM

Go on, admit it. At some point in your life you've written down a password on a piece of paper in clear text. Anybody walking by can simply glance at your note, and they'll know what your password is.

No, you have never done that? Excellent. 

But if you've ever used your web browser to log into a website over the web, and entered sensitive information like your password without encryption, you've effectively transmitted that information through the internet for all to see, almost like writing it on paper and showing it around.

Whoa.

groov EPIC Security Series, Part 4: User Accounts

Posted by Ben Orchard on May 10, 2019 3:12:44 PM

In this blog post, let’s take a closer look at user accounts on the groov EPIC system, and how you can improve your system security by giving users and services fine-grained access to applications running on EPIC. In other words, make sure each person or service has only the access they really need and nothing more.

But before we get deep into user accounts, let’s first discuss user account credentials. Take a moment and ask yourself the following questions:

  • Do you use the same password for multiple accounts?
  • Do you use a mix of punctuation and capital letters in your passwords?
  • Do you use long phrases as your passwords?

groov EPIC Security Series Part 3: Device originating communications, or how and why MQTT rocks

Posted by Ben Orchard on Apr 29, 2019 9:15:28 AM

The story goes that a valve manufacturer wanted to have their networked smart valves certified for use in a nuclear reactor plant. The smart valve could report all sorts of critical data points to a database system and also be controlled by that SCADA system in the plant. But to get it certified for use, the smart valve had to undergo a rigorous security audit by the information technology (IT) department at the plant.

groov EPIC Security Series, Part 2: What's a Firewall?

Posted by Ben Orchard on Apr 17, 2019 2:41:07 PM

Ever notice how emergency exits in a building open outward? Then, to keep the building secure, they are usually locked from the outside. You can get out easily enough, but you can’t get in that way.

However, on a building’s main front entrance, the door often swings in so you can enter. Typically, there is a security guard or perhaps a receptionist there to check your ID and keep an eye on the comings and goings.

groov EPIC Security Series, Part 1: Dual Network Interfaces

Posted by Ben Orchard on Apr 9, 2019 8:45:46 AM

Trusted and untrusted: when it comes to people, it can be hard to know someone at first pass. You need some time to build a picture of the person.

When it comes to networking, it’s a little more cut and dried. You either know who’s on a network or you don’t.

Can it really be that simple? Is there really a way on a groov EPIC to keep those you don’t trust away from those you do?

WannaCry Ransomware. Is Your SCADA Network At Risk?

Posted by Matt Newton on May 16, 2017 8:00:00 AM

Undoubtedly you’ve heard of the most recent ransomware attack plaguing the globe. It started late last week and so far has infected machines across 150 countries.

As the name suggests, the virus in effect holds the infected computer hostage and demands that the victim pay a ransom in order to regain access to the files on his or her computer. You can learn more about ransomware in this previous blog post.

But let’s get down to what you need to know. Here are the latest facts about WannaCry that you need to be aware of to make sure your systems are not at risk.

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.
