by Stephanie Neil, MA Editorial Staff Posted on Wednesday, April 09, 2008 5:04:06 PM   Yokogawa Electric Corp. has selected the Tofino Industrial Security Solution, an industrial firewall jointly development by MTL Instruments (a part of Cooper Crouse-Hinds) and Byres Security Inc., for use with Yokogawa's CENTUM CS 3000 production control system and its STARDOM network-based control system.
The Tofino firewalls are small, industrially hardened security appliances deployed throughout a refinery or industrial plant and centrally managed for a coordinated security approach. Each Tofino security appliance is placed in front of one or more mission-critical control devices, such as the STARDOM industrial controller, as well as the sub-system interfaces of CS 3000, which run the open industrial protocols, and then tuned to meet the security requirements of those systems.
Yokogawa's use of the Tofino Industrial Security Solution will enable SCADA and process control equipment customers to deploy multi-layer security in the process control network.
The Tofino solution is designed by control engineers for control engineers so that they can focus on keeping a system reliable, yet secure, thus meeting or exceeding all the available standards and regulations.
"If companies want to meet the new ANSI/ISA-99 security standards, it is critical they divide up their plant operations into security zones and then protect each zone in the most appropriate manner," said Eric Byres, CTO of Byres Security, in a statement. "It is no longer good security practice or cost-effective just to lump everything together behind one big firewall and pray that you are secure."
