ISA/IEC 62443 PROGRAM
IC33Cybersecurity Risk Assessment for New and Existing Industrial Systems
Version 4.00
Assess IACS systems and document their cybersecurity requirements.

From assessment to
security requirements.
Learn to systematically assess existing and new industrial automation and control systems (IACS), identify vulnerabilities, analyze threats and consequences, and develop a risk-based cybersecurity requirements specification (CRS).
IC33 begins with the first phase of the IACS Cybersecurity Lifecycle, as defined in ISA/IEC-62443-1-1. Students identify and document IACS assets and assess cybersecurity vulnerabilities and risks to understand the high-risk vulnerabilities that require mitigation. Under ISA/IEC-62443-2-1, these assessments apply to both new (greenfield) and existing (brownfield) applications.
The assessment process includes developing a zone and conduit model, identifying security level targets, and documenting project cybersecurity requirements in a CRS.

ISA certification
IC33 is the second course in the ISA/IEC-62443 Cybersecurity Certificate Program. Pass the exam to earn the ISA/IEC-62443 Cybersecurity Risk Assessment Specialist certificate.
Course registration includes one exam fee. The certification exam is in English.
A certificate of completion indicating the total number of CEUs earned is provided upon successful completion of the course.
Completion of training and earning the professional certificate are separate: the certificate requires passing the examination.
Who should attend?

Training scope
ISA training focuses on helping participants correctly understand and interpret the requirements of the ISA/IEC-62443 series of standards and what needs to be done. Laboratory exercises and products support understanding of the concepts. The course does not aim to recommend a particular solution or demonstrate how to comply with every requirement.
