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…

When you have a job to do, tools that are simple to use and designed for your industry go a long way towards helping you achieve results.

Industrial facilities are staffed by engineers, technicians and maintenance people, not security experts, so complicated IT firewalls are just that - complicated.

That’s why our firewalls have graphical tools that help controls specialists build traffic rules using terms and concepts that are familiar to them. For example, most engineers who use automation products do not know much about the control traffic traveling over their network. The system just works.

A capability of our devices, Firewall Learning Mode, removes a lot of the difficulty of configuring and testing firewalls. It also greatly reduces a traditional installation risk – network interruptions. Let’s find out more.

The days of connecting devices to the network but not really knowing the impact on security are limited.

Two trends are converging to make this practice extinct. The first is the heighted concern about security from both reliability and risk management perspectives.

The second is the Industrial Internet of Things (IIoT) which is leading to connecting more devices and systems to the industrial network, thereby exposing it to more risk.

The good news is there is an easy way to improve your ICS security knowledge and skills. That way is to attend our upcoming Industrial Ethernet Infrastructure (IEI) Design Seminar, being held Oct. 19-22, 2015 near Chicago, Illinois.

Read on to find out more about this event -- you don’t want to miss the early bird registration deadline of July 31, 2015.

The Internet of Things means more and more devices are being connected to industrial networks. And these “things” aren’t just the controllers and related computers “owned” by the OT department or the computers and network devices “owned” by the IT department.

The “things” might also include everything from physical security IP cameras and networked badge readers to HVAC systems and mobile devices.

Given the mammoth nature of this change, we decided to work with our corporate sibling, Tripwire, to poll IT and ICS security experts about it. We asked them:

1. How the IoT changes the dynamics between IT and OT
2. What practical tips they have for how the two groups can work together effectively

Today we present their responses and explain how they add up to news you might want to be sitting down to read –there are three ways OT and IT have to change.

Recently a previously identified malware, named Duqu , re-emerged in a very surprising way. It was detected attacking the systems of Kaspersky Lab, one of the leading cyber security firms in the world. And, it wasn’t just that it went after the experts’ systems that is amazing, what is also amazing is how it did it.

Kaspersky researchers said that “The philosophy and way of thinking of the ’Duqu 2.0‘ group is a generation ahead of anything seen in the APT world.” (APT stands for Advanced Persistent Threat.)

What is this new malware and how does it relate to ICS security?

While not a threat to ICS as far as we know today, it is a reminder that APTs are a type of risk that industrial operators should be evaluating on an ongoing basis. The goal here is to inform you, not alarm you, about this unique threat. Then we’ll revisit the best practices for defending industrial systems against APTs.

“Engineers not specializing in cyber security often throw their hands up at security, it’s not what they do,” says Pat Differ, Director of Sales at Securicon LLC, a consulting firm specializing in cyber security services and solutions for critical infrastructure industries. “The result is they may end up relying heavily on IT-oriented or recommended solutions that are not meant for industrial applications.”

If this bears any resemblance to what is happening in your organization, we have good news for you. Belden has recently teamed up with Securicon to provide one-stop security solutions to our customers.

I recently had the opportunity to speak to Pat and Securicon’s CEO, Paul Hurley, to find out their thoughts on the state of industrial security. Read on to find out their innovative ideas about how to move forward on cyber security.
