The Tofino OPC Enforcer firewall—part of the Tofino Industrial Security Solution—is designed to lock down any industrial network using the previously hard-to-secure OPC Classic protocol.
Using deep packet inspection firewall technology, the Tofino OPC
Enforcer provides superior security over what can be achieved with
conventional firewall solutions, says the vendor. The Tofino OPC
Enforcer is intended to provide robust security and stability for any
system using OPC DA, HAD or A&E. Unlike other firewalls, the 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. The OPC Enforcer is implemented
without any control-system changes. The Tofino hardware is simply
installed into the live network and configured using a drag-and-drop
editor to select permitted clients and servers.Byres Security Inc.www.tofinosecurity.com250.390.1333
