Overview of the ISA/IEC 62443 Standards & Effective IACS Security
Summary: This Dragos blog is the second in a series on the ISA/IEC 62443 standards, offering a detailed overview of the documents within the series after a first post gave a general overview. The series aims to improve the reliability, integrity, and security of IACS through a risk-based, methodical process, and is referenced throughout the NIST Cybersecurity Framework and extensively in the CISA Cybersecurity Performance Goals, which cite ISA/IEC 62443-2-1 and 62443-3-3 in almost every category.
What you should know: The standards are functional - they set security performance objectives but do not define how to meet them - and adoption of any level is optional and dependent on a risk assessment of the network, leaving the translation into an actionable plan to the asset owner.
