System integration: Incorporating safety into a machine or a process at the design stage is more cost-effective than doing so later. Here’s a look at how several integrators and manufacturers approach upfront safety integration and the resulting benefits.

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.
