Enhance Control System Security Using Process Switches

Enhance Control System Security Using Process Switches

In today’s world of standardized communications, no man is an island and neither is any process control system. Networking is about to expand greatly, thanks to the increasing adoption of integrated devices, the internet, and a proliferation of open operating systems. Increasing attacks that exploit weaknesses in the network may not be far behind. Real world examples have shown that control systems can be hacked, sometimes with deadly results.

This white paper looks at how open Microsoft technology used in virtually all contemporary control systems, such as distributed control systems (DCS) and supervisory control and data acquisition (SCADA), can mean less security. The paper explores why current solutions may not be up to the task of protection. It also shows how simple, yet reliable electro-mechanical switch-based protection can improve cyber defenses by complementing traditional techniques with another layer of protection independent of centralized control systems.
