IEC 62443 Training

This training provides you with an overview of the IEC 62443 series of standards. It presents the main cybersecurity concepts in industrial security and includes an overview of all the requirements contained in IEC 62443.

The training can be used by both cybersecurity professionals focusing on Information Technology (IT) to gain a deeper understanding of Operational Technology (OT) and also by OT professionals to gain a better understanding of cybersecurity.

About IEC 62443 Series of Standards

IEC 62443 is an internationally recognized family of standards providing a complete framework for assessing various actors involved in OT, also known as Industrial Automation and Control Systems (IACS). Initially designed for Industrial Control Systems (ICS), IEC 62443 is now considered a relevant standard across many industry verticals due to the holistic way in which its requirements are expressed. The series of standards was created in line with this increasing awareness of OT security.

The series of standards are divided into different sections that cover both technical and process-related aspects of OT cybersecurity. Moreover, it divides the topics of cybersecurity based on the responsibilities of various stakeholders, such as operators, service providers, and component/system manufacturers.

The documents included in IEC 62443 standards are split into four levels:

  • General concepts;
  • Policies & Procedures;
  • System level;
  • Component level.
