ISA/IEC 62443 is a series of standards that define procedures for implementing electronically secure Industrial Automation and Control Systems (IACS). It addresses security for operational technology (OT) environments, which are crucial for industries like manufacturing, energy, and transportation. The standards provide a framework for assessing and mitigating cybersecurity risks to ensure the availability, integrity, and confidentiality of critical infrastructure and industrial processes. They cover various aspects, including security levels, risk assessment, security management, system design, and component requirements, aiming to establish a robust cybersecurity posture across the entire IACS lifecycle.
