Byres Security Introduces Tofino OPC Enforcer Firewall

Byres Security Inc has announced the release of the new Tofino OPC Enforcer firewall, part of the Tofino Industrial Security Solution. This module uses deep packet inspection firewall technology and locks down any industrial network using the previously hard to secure OPC Classic protocol.

Byres claims this product inspects, tracks and secures every connection made by an OPC application, opening only the exact TCP port required for a connection between an OPC client and server.

It is implemented without requiring any changes to the control system. The Tofino hardware is simply installed into the live network and configured using a drag and drop editor to select permitted clients and servers. Once installed, network security is assured, with all OPC traffic managed behind the scenes. A downloadable White Paper titled “Securing Your OPC Classic Control System” is also published on OPC Feature Page.
