Said to be the first firewall that protects integrated applications based on OPC Classic, the Triconex/Tofino OPC firewall is designed to harden the vendor’s Triconex industrial safety systems against network accidents and attacks.
Triconex safety systems include embedded OPC servers within their Tricon
communications module (TCM). To ensure that these modules are cyber
secure, the vendor teamed with Byres Security Inc. to create a firewall
specifically for Triconex systems. The two companies enlisted the
services of MTL Instruments to build the security hardware. Users can
deploy the firewall in front of the Triconex OPC server to thwart
attacks and traffic storms before they reach the safety and critical
control system. It automatically mitigates risks related to previously
published DCOM vulnerabilities, while providing packet management and
rate limiting to prevent network traffic problems that could have an
adverse effect on the stability of the safety system.Invensys Operations Managementwww.iom.invensys.com888.869.0059
