New ISA/IEC Cybersecurity Standard Provides Auditable Approach to Assessing Cyber Risk

“Currently, there is wide degree of variability in how industry defines and conducts IACS risk assessments,” says John Cusimano of aeSolutions, who led the ISA99 subgroup that wrote the standard. “ISA/IEC 62443-3-2 establishes fundamental requirements for an IACS risk assessment without being overly prescriptive. The result is a standard that will bring uniformity across industry while still allowing IACS owners and operators to apply any methodology that is compliant with the standard.”   


The new standard, ISA/IEC 62443-3-2: Security Risk Assessment for System Design, defines a comprehensive set of engineering measures to guide organizations through the essential process of assessing the risk of a particular IACS and identifying and applying security countermeasures to reduce that risk to tolerable levels.
