Over the past decade or more the need for cyber security in industrial automation and control systems has been accelerating at an ever-increasing rate. Adoption of the benefits of commercial off-the-shelf and open technologies, awareness of the systems, exposure of the systems and precedents set by previous attacks have all contributed to the increase.

The advent of the Industrial Internet of Things (IIoT) pushes this even further with the increased uptake and reduced cost of powerful computing technologies like cloud, virtualization, shared networks and so on. How can IIoT and cyber security standards progress in tandem, to ensure that our increased capabilities are protected by increased security? Click Read More to learn how.

Do you believe that your control system is in more danger from cyberattacks now than it was a year ago? How does this compare with what other organizations are experiencing? How does your company compare to others in terms of doing security assessments?

If any of these questions are of interest, you will want to study the “SANS 2016 State of ICS Security Survey” report. As I mentioned in a recent article on where to find hard-to-get ICS security data, this is one of the only no-charge sources of ICS security data available.

Last year when I reviewed the 2015 results, I summarized the security controls recommended by SANS. This year I am going to comment on 3 aspects of the report’s findings: security threats and perceptions, security visibility and the convergence of IT and OT. Read on to learn more and to find out where to obtain the report and related resources.

One of the best parts of the Belden Design Seminar, held last week in Chicago, was the lively presentation given by two of Belden and Tripwire’s top experts on industrial cybersecurity.

David Meltzer, Chief Research Officer of Tripwire, and Jeff Caldwell, Chief Architect- Security at Belden, teamed up to discuss cybersecurity threats and how to build industrial networks to defend against them.

David and Jeff spoke about the nature of cybersecurity incidents occurring in industrial networks today. They went on to discuss a 1-2-3 approach to securing industrial networks. Find out about this approach and how Belden and Tripwire products contribute to it.

Do you have a visual map of your Ethernet communications infrastructure?

Can you quickly tell which links are up and which are down on your network?

Are you notified when a rogue device is added?

Do you know which devices and protocols are locked down from a security perspective?

If not, it’s time to find out about network management software (NMS)

How is your organization doing relative to others in terms of how many security breaches occur on your control systems and how well you identify their sources? What about the size of your security budget versus others? Or how well you are managing the convergence of IT and OT systems?

If you would like to know the answers to these questions, the SANS Institute has a report for you. And, the good news is you can download it for free.
   
The results of the 2015 SANS survey to more than 300 industrial respondents are now available. I want to draw your attention to this useful resource and to highlight a few of its findings. I also want to point out a few areas where Belden’s experience and recommendations are slightly different than those of SANS.

If you’re like me, when you don’t know how to do something you avoid or delay doing it. Even though I love learning new things and tackling new adventures, in the context of work, there never seems to be enough time. That means taking on a new challenge or learning best practices about a new topic is often put on the back burner.

If cyber security is a new area for you, then this is an article you really want to read. It is short and it explains three important concepts that once you know, you can start putting into practice right away.

Think of it this way, cyber security is a topic of high concern at the top levels of all companies. Plus, the Industrial Internet of Things (IIoT) is connecting more devices and systems to the control network, increasing the likelihood of cyber incidents. It’s more important now than ever before to understand the principles of cyber security. Let’s get started…

Due to a “if it ain’t broke, don’t fix it” mentality, our industry has historically resisted, rather than embraced, emerging technology. Thankfully – and not a moment too soon – experts have started to take advantage of the technologies at their disposal in one key area: security.

As a whole, however, security can be overwhelming. While many managers and engineers know they need to implement some sort of network security measures to protect their operations, they often times don’t know where to begin. And with that uncertainty (or lack of budget), they may not spring into action unless forced.
