Jan 1, 2007 · The ISA/IEC 62443 series of standards define requirements and processes for implementing and maintaining electronically secure industrial automation and control systems (IACS). These standards set best practices for security and provide a way to assess the level of security performance.

The ISA industrial cybersecurity training courses and knowledge-based certificate recognition program are based on ISA/IEC 62443 —the world’s only consensus-based series of automation cybersecurity standards, and a key component of government cybersecurity plans.

ISA actively participates in the world’s primary international standards system as sanctioned by the United Nations and operated by the Geneva-based International Electrotechnical Organization (IEC) and International Organization for Standardization (ISO).

IEC 62443 is a series of standards that address security for operational technology in automation and control systems. The series is divided into different sections and describes both technical and process-related aspects of automation and control systems security.

The ISA/IEC 62443 series builds on established standards for the security of general-purpose information technology systems (e.g., the ISO/IEC 27000 series), identifying and addressing the important differences present in Industrial Automation and Control Systems (IACS).

The ISA Global Cybersecurity Alliance (ISAGCA) has officially released its first work product — a user-friendly overview of the ISA/IEC 62443 Series of Standards, the world's only consensus-based automation cybersecurity standards.
