Integrating ICS Cybersecurity and Process Safety Management (PSM)

The majority of process plants today are controlled and operated by automation systems built on Ethernet TCP/IP networks and legacy Microsoft operating systems. These systems are vulnerable to cybersecurity breaches resulting in potentially significant risks. Standards have been developed on how to assess and mitigate cyber risks to these systems. This paper provides an introductory summary of these topics.
