Honeywell chooses Tofino firewall for OneWireless system

Tofino security device will sit between the OneWireless networks and Experion PKS to block harmful traffic. Hirschmann also partnering with Byres for security devices.


Honeywell Process Solutions has selected Tofino firewall technology from Byres Security Inc . to provide a critical level of protection between OneWireless networks and Experion PKS (Process Knowledge System). The device will provide a critical layer of protection against unwanted and harmful network traffic, thereby promoting control system integrity. The product is available today from Honeywell.

The OneWireless firewall is compliant with Experion R311. Byres says this is the second network security product from Honeywell based on Tofino technology, the first being the Experion Modbus TCP firewall.

Byres says the selection by Honeywell centers on ease of use. Unlike IT-style firewalls that require highly-trained staff for installation, the OneWireless firewall automatically works as soon as it is connected to the network. The product filters bi-directional network traffic, allowing only wireless I/O on both directions, while blocking other data types.

"Honeywell is taking a holistic view of security by protecting both its OneWireless networks and wired communications, such as Experion control networks, with multiple layers of protection," says Eric Byres, CTO of Byres Security Inc. "The Tofino technology in the OneWireless firewall provides an easy way for Honeywell's customers to achieve in-depth security with a simple zero-configuration module."

In related news, Hirschmann (division of Belden) and Byres have signed a technology cooperation agreement to launch new products jointly in the area of industrial network security, with availability later this year.

"Belden provides effective signal transmission solutions that include network devices designed for safety-critical applications for SCADA and industrial automation" says Mark Cooksley, product manager for network security at Belden. "We are pleased to partner with Byres Security. Their deep expertise in the area of industrial security and their proven ability to deliver pragmatic solutions will add value to our Hirschmann range of automation and networking systems."

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
