Which standard within the ISA/IEC 62443 series focuses specifically on risk assessment?

The standard within the ISA/IEC 62443 series that focuses specifically on risk assessment is indeed ISA/IEC 62443-3-2. This part of the series is dedicated to defining technical security requirements for IACS (Industrial Automation and Control Systems) and addresses how to perform a risk assessment relative to these systems.

ISA/IEC 62443-3-2 emphasizes the importance of understanding the various types of risks that can affect the cybersecurity of IACS. It outlines methodologies for risk identification, assessment, and mitigation, making it crucial for organizations to establish a robust risk management strategy. By focusing on these aspects, the standard provides a framework for organizations to evaluate their security posture and assess potential vulnerabilities effectively.

In contrast, the other options focus on different domains within cybersecurity for industrial systems. For instance, ISA/IEC 62443-2-1 relates to an effective security program for automation and control systems, ISA/IEC 62443-1-1 covers foundational requirements for security across IACS environments, and ISA/IEC 62443-4-1 is focused on requirements for software development and supply chain management. Each serves a unique purpose, but none are solely centered on the process of risk assessment like ISA/IEC 624
