Securing Your OPC Classic Control System
August 2010
by Eric Byres, security expert and CTO of Byres Security and Thomas J. Burke, President, OPC Foundation.
OPC Classic is a software interface technology used to facilitate the transfer of data between different industrial control systems. It is widely used to interconnect Human Machine Interface (HMI) workstations, data historians and other hosts on the control network with enterprise databases, Enterprise Resource Planning (ERP) systems and other business-oriented software. Unfortunately, securely deploying OPC Classic has proven to be a challenge until recently.

High Security Integration Using OPC
April 2010
OPC Classic, the popular industrial integration standard based on DCOM, has made the interfacing of different industrial control products significantly easy. Unfortunately, it also brought with it a number of serious security concerns for the designers of control, SCADA and safety systems.
This White Paper looks at these issues and reviews the solutions proposed over the past decade from researchers and academics. It looks at new technologies in advanced firewall port management and embedded OPC servers that offer true defense-in-depth and read-only security for better reliability and security of all control systems, but especially for safety integrated systems.
