Getting Defensive

Invensys Operations Management (Plano, TX) offers the new Triconex® / TofinoTM OPC firewall, a cyber security solution designed to prevent industrial safety systems against network accidents and attacks. According to the company, it is the first firewall that protects integrated applications based on OPC Classic, a widely-used industrial integration protocol. Users deploy the new firewall in front of the Triconex OPC server, thwarting attacks and traffic storms before they reach the safety and critical control system. The firewall 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.
