Update on ISA/IEC 62443 Series and Security Protection Schemes

The International Society of Automation (ISA), a prominent organization in the field of automation, has recently launched ISA-TR62443-2-2-2025, which focuses on security measures for Industrial Automation and Control Systems (IACS). This publication serves as an essential update to the ISA/IEC 62443 series, which is a globally recognized set of standards for cybersecurity within automation and control systems.

ISA-TR62443-2-2-2025 provides practical guidance to industries on establishing, operating, validating, and maintaining a thorough Security Protection Scheme (SPS) aimed at safeguarding IACS in various operational environments. The report builds on foundational elements from the existing ISA/IEC 62443 framework, incorporating established requirements and offering models for assessment and validation.

Emphasis on Risk Management

A primary objective of this document is to equip asset owners and operators with the necessary tools and procedures to address the risks posed by cyber threats affecting IACS. "ISA‑TR62443‑2‑2 offers a risk-based approach to everyday security actions," says Eric Cosman, co-chair of ISA99. This highlights the report’s focus on creating a robust structure that combines technical controls, process maturity, and designated responsibilities.

The guidance found within this report helps organizations maintain cybersecurity resilience throughout the entire lifecycle of IACS, ensuring continuous protection against evolving cyber threats. Companies leveraging these standards will be in a better position to navigate the complexities of cyber risk management and implement defensive strategies tailored to their specific operational contexts.

Strengthening Cybersecurity Awareness

The ISA is a non-profit professional community founded in 1945, dedicated to advancing automation through the development of global standards and knowledge sharing among its members. Their efforts, particularly in developing the ISA/IEC 62443 series, highlight the organization's commitment to enhancing cybersecurity awareness, education, and collaboration.

In addition to the publication of the new report, ISA has also established the ISA Global Cybersecurity Alliance (ISAGCA). This collaborative forum aims to elevate awareness and promote best practices in operational technology (OT) cybersecurity, drawing representation from over 50 companies and industry groups, which collectively command revenues exceeding $1.5 trillion. The ISAGCA emphasizes the importance of standardization and education to create a safer and more secure industrial automation landscape.

Conclusion

As cyber threats continue to increase in both frequency and sophistication, the insights brought forth by the ISA/IEC 62443 series and the new ISA-TR62443-2-2-2025 report are crucial for organizations seeking to bolster their cybersecurity posture. By adopting a proactive approach and implementing the frameworks provided, organizations can mitigate risks, protect assets, and sustain their operations amidst an increasingly complex digital environment.
