Firewall for industrial networks
Tofino™

The TofinoTM Industrial Security System is a new and unique, solution from MTL and Byres Security that addresses the important issue of protecting Industrial Networks from modern cyber-security attacks.

The conventional approach is to employ a standard, but highly complex, "IT-style" professional firewall. Such methods are complicated and require highly-trained staff to install and manage them. TofinoTM was designed with its environment, the level of staffing and the needs of industry in mind. As a result, a field technician can simply attach power to a TofinoTM appliance, connect two network cables and then walk away - it's that simple to install.

From there, the company security staff can sit at a central management platform (CMP) and configure and monitor any system with ease, reacting to threats in a coordinated and company-wide manner. Best of all, the system has the flexibility to adapt to a small plant with a single PLC, or meet the needs of a multi-national organization with thousands of critical devices scattered around the globe.

By deploying TofinoTM security appliances directly in front of each control device (or group of devices) that needs protection, they provide SCADA and process governor companies with a layered security solution for their systems. Incorporating dynamically Loadable Security Modules (LSMs), these appliances provide protection directly in front of the critical edge device. This is similar to the way that firewalls (such as Norton FirewallTM and Windows® Firewall), antivirus software (such as Symantec AntiVirusTM) or Intrusion Detection Systems (such as TripWireTM) provide local protection for desktop professional computers. This allows a "defense-in-depth" strategy to be used, so if a hacker or virus penetrates or bypasses a main corporate firewall, they will still be faced with an array of SCADA-focused security devices that need to be breached before any damage can be done.
