Effective OPC security for control systems
05 July 2011
For the past decade, industrial control systems administrators and engineers wanted to believe that ‘air gaps’ or ‘security by obscurity’ would keep them safe from security threats. Those days are over - recent security incidents, such as the Stuxnet worm, are a loud wakeup call for the industrial automation industry.
A whitepaper explains the security advantages of limiting network interfaces and protocols, and recommends using OPC as a communications standard because of its ease of use and its widespread deployment.
It goes on to discuss how different defensive layers can be employed to provide high security when using OPC technology. The paper also outlines a simple and cost effective way to secure OPC that can be deployed in almost any industrial facility.
The authors of the white paper are Eric Byres, CTO, Byres Security Inc and Darek Kominek, manager, OPC Marketing, MatrikonOPC
