Technical Overview

The 9202-ETS-MM-SC is a high-performance industrial security appliance specifically designed for SCADA and process control networks that utilize fiber optic backbones. Unlike standard copper-based firewalls, this model features dual 100BASE-FX multimode fiber interfaces, allowing for secure, EMI-resistant communication over distances up to 5,000 meters.

Operating as a transparent Layer 2 bridge, the 9202-ETS-MM-SC provides "plug-and-protect" security. It can be installed into existing fiber links without requiring IP address changes or network re-engineering. This makes it an essential tool for isolating critical control zones (such as turbine controllers or PLC clusters) from broader plant networks, effectively mitigating the risk of malware propagation and unauthorized access.

Application and Cyber Defense

The 9202-ETS-MM-SC is ideally suited for large-scale industrial sites like refineries, offshore platforms, and power plants where long-distance fiber runs are standard. By enforcing protocol-specific rules (DPI), the appliance doesn't just block IP addresses; it inspects the actual commands being sent to the hardware. For example, it can be configured to allow a workstation to "Read" data from a PLC via Modbus while blocking any "Write" or "Programming" commands, ensuring that only authorized operational changes can occur.
