Recently we looked at the state of ICS security according to the 2016 SANS survey and commented on how a broader set of tools is becoming available to secure industrial automation systems. Many industrial engineers will likely not be familiar with these new-to-ICS technologies.

However, it’s important to know about the universe of available industrial security solutions. If new solutions are being considered for use, plant staff need to contribute expertise to their selection and deployment so that
mission-critical operations are protected.

Thus, with the goal of informing you about some of the newer industrial security products and approaches now available for manufacturing and process control systems, this article looks at Belden’s partnership with FireEye.

PoE can enable fast installation and deployment, lower operating costs and maximum reliability for today’s enterprise networks. As PoE changes to meet growing technology and application requirements, it is being classified by classes. PoE devices, on the other hand, are categorized by type depending on their power requirements. The difference between PoE “types” and “classes” can sometimes cause confusion when talking about PoE applications and capabilities.

In this blog, we offer a breakdown of the four PoE types – Type 1, Type 2, Type 3 and Type 4 – and where they’re used, along with other terms used to describe them.

As the ANSI/TIA-942-B standard is under development, it’s important to understand the new technology advances that impact it, as well as the difference between normative and informative guidance when it comes to using the ANSI/TIA-942-B document.

Two new media types have been approved by TIA as part of ANSI/TIA-942-B: Category 8 cabling and wideband multimode fiber. Here’s what we know so far about these two media types and what will be included in ANSI/TIA-942-B.

In Part 1 of this series I described how global competition and the IIoT are changing the industrial automation model. In the new model, the majority of the control function occurs at the field-level, a massive change that requires new kinds of field-level devices.

The new devices will be “plug-and-produce,” that is, they are simply connected, turned on and presto! - they work. Many of them will also include programmable logic control features. These flexible, modular field-level devices will facilitate quick manufacturing changes, thereby getting products to market faster and cheaper. This is a key capability of the Smart Factory of the Future.

What do plug-and produce-devices mean for the control and communication infrastructure of tomorrow? Deepen your IIoT knowledge by reading on to learn about the next generation of field-level devices.

With all this talk of smart buildings, convergence and the Internet of Things, it’s important to remember: The only way a building or business can benefit from these trends is by having the right network backbone (LAN) in place.

Today’s networks must be able to ensure uptime, plenty of bandwidth, security and scalability – ideally while keeping energy, cooling, material and labor costs to a minimum.

For this reason, passive optical LANs (POLANs or POLs) are starting to be considered for new deployments. But what distinguishes a passive optical LAN from a passive optical network?

There’s no question that improving energy efficiency saves data center owners money, but there are other benefits to consider as well. Lowering data center power consumption can extend IT equipment lifecycles, decrease organizational environmental impact and footprint, reduce the amount of unplanned downtime due to outages or equipment overheating and improve mechanical and electrical system capacity. Data centers still have room for improvement when it comes to power consumption, and these 6 energy-efficiency tips may help...

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.

So you want to upgrade to a 4K system? There are several options when it comes to the type of signal your 4K system can send to display 4K images. To understand which option your AV application might require, it helps to understand what can make up a 4K image signal.
