Understanding the Importance of Risk Registers in OT Cybersecurity
OT cyber-risk encompasses a wide range of threats and vulnerabilities that can disrupt industrial operations, lead to financial losses, and even pose safety hazards. Risk registers are essential tools in managing these OT cyber risks, offering a structured approach to identifying, assessing, and prioritizing the risks that could affect an organization’s OT environment.
In a recent discussion with Industrial Cyber, cybersecurity experts shed light on the crucial role of maintaining risk registers in OT cybersecurity. They also explored how often these registers should be reviewed and updated to stay effective.
Marco (Marc) Ayala, President of InfraGard Houston Members Alliance, emphasized the foundational role of risk registers in ICS/OT cybersecurity. He stated, “A risk register is indispensable for identifying, assessing, and prioritizing risks that could impact operational technology. By maintaining this register, organizations ensure they systematically address potential vulnerabilities and allocate resources where they are most needed.”
Ian Bramson, Vice President for Global Industrial Cybersecurity at Black & Veatch, highlighted the importance of a risk-based approach to cybersecurity. “Companies have limited resources to keep up with a constantly changing threat environment. A risk-based approach to cyber is key to optimizing security posture and effectively investing resources. Developing and managing a strong risk register is essential for adapting to evolving threats.”
Durgesh Kalya, Network Security Expert at Covestro, further elaborated on the critical role of OT in ensuring business continuity, particularly in the process industry. “Operational Technology (OT) is a crucial enabler for automation and is closely linked to the license to operate, as many environmental and monitoring systems fall under OT. It’s vital for organizations to clearly define what constitutes OT within their specific context, as this can vary widely.”
Sinclair Koelemij, an ICS security professional, outlined the multiple benefits of maintaining a risk register in OT cybersecurity. He noted that it provides a comprehensive view of potential risks, enables prioritization and mitigation, ensures accountability, aids in regulatory compliance, supports informed decision-making, assists in incident response and recovery, and fosters continuous improvement in risk management. By maintaining a risk register, organizations can manage risks on a daily basis.
This conversation underscores the significance of risk registers as a foundational element of effective OT cybersecurity, helping organizations navigate the complexities of protecting their critical infrastructure.
