How should OT system owners be involved in security governance?

• A. Exclude OT owners; governance should be handled by IT security teams.
• B. Assign OT owners to risk assessments only.
• C. Include OT owners in risk assessments, change approvals, incident response planning, and regular security briefings; assign clear accountability.
• D. Inform OT owners after major incidents only.

Answer: (C)

In security governance, the people who own OT assets must be part of the ongoing decision-making because they hold the deepest understanding of how a process operates, what safety constraints exist, and what levels of disruption are acceptable. Including OT owners in risk assessments brings process specifics into the picture—they can interpret threats and vulnerabilities in terms of real-world impact on production, safety, and uptime, ensuring that risk evaluations reflect operational realities rather than just abstract scores. Involving them in change approvals helps ensure that security controls or configuration changes won’t compromise safety or production continuity, and that any proposed change can be implemented within the plant’s constraints and maintenance windows. When planning incident response, OT owners provide critical context about potential process effects and recovery priorities, guiding containment and restoration actions in a way that minimizes risk to people and equipment. Regular security briefings keep OT teams informed about evolving threats, remediation options, and patching schedules so security measures stay aligned with actual operation cycles and safety requirements. Clear accountability is essential too—knowing who owns the risk, who makes decisions, and who coordinates response reduces confusion during incidents and ensures governance is effective. Excluding OT owners or restricting their involvement to a single activity creates gaps between security and operations, leading to controls that are hard to implement or unsustainable, missed incidents, and slower, less coordinated responses. Merely assigning OT owners to risk assessments without broader participation still leaves change management, incident planning, and ongoing communication underinvolved. Informing OT owners only after major incidents misses proactive governance and the opportunity to design safer, more resilient processes.
