How can I use my PHA to Streamline Cybersecurity Risk Assessment?

29 April 2021

Many organizations have mature processes in place for evaluating process or machinery hazards in traditional safety risk assessments, but fewer have developed a robust approach to cybersecurity risk assessment. Alignment between safety risk assessment and cybersecurity risk assessment is critical, and the 2016 version of IEC 61511 now requires that a cybersecurity risk assessment be conducted for all Safety Instrumented Systems (SIS) and connected systems. Fortunately, traditional process hazard analyses (PHAs) have valuable information that can be used to improve the speed and efficiency of the cybersecurity assessment, including corporate risk criteria, potential consequences resulting from control system failures, severity rankings for consequence scenarios, existing mechanical protection layers. With this information organizations can jumpstart their approach to managing cybersecurity risk.
