ISA/IEC 62443

ISA/IEC 62443 is an international set of standards designed to protect industrial control systems—like those in factories, energy plants, and critical infrastructure—from cyber threats. It provides guidelines for establishing secure practices, managing risks, and implementing protective measures throughout the entire system lifecycle. The goal is to ensure these systems operate safely and reliably, minimizing vulnerabilities that cyber attacks could exploit. Think of it as a comprehensive security framework specifically tailored for the industrial technology that keeps essential services running smoothly.
