Yokogawas Comprehensive Lifecycle Approach to Process Control System Cyber-Security
Todays process control systems can take advantage of advanced general-purpose IT to reduce costs, improve performance, enable interoperability and add other important new capabili-ties. However, the very same technologies make todays industrial systems increasingly vulnerable to security intrusions – malicious or otherwise – from both within and without the plant. Certainly, the IT world has devel-oped powerful tools and techniques to help prevent, identify, and mitigate the effects of intrusions. However, requirements specific to industrial systems (such as the need to maintain nonstop operations and provide deter-ministic response) often make employing these tools and techniques in industrial environments problematic.
