Which of the following lists the components of a risk assessment for securing a utility OT environment?

• A. Asset inventory, threat modeling, vulnerability assessment, impact analysis, likelihood estimation, control catalog, risk computation process
• B. Asset inventory, threat modeling, patch management, rollback plans, incident response
• C. Threat modeling, vulnerability scanning, network topology, change management
• D. Impact analysis, asset disposal, vendor risk, governance framework

Answer: (A)

In securing a utility OT environment, a comprehensive risk assessment starts with knowing what you need to protect and then examining how threats could exploit weaknesses and what impact that would have. That sequence is captured by including asset inventory to identify all critical assets, threat modeling to map out potential attacker pathways and scenarios, and vulnerability assessment to uncover weaknesses that could be exploited. From there, impact analysis explains what happens if a risk materializes, and likelihood estimation helps quantify how probable it is. A control catalog is then used to list the safeguards available or planned, and a risk computation process ties everything together to produce a risk level that guides prioritization. Together, these components form a complete, structured approach to evaluating and prioritizing security in an OT setting. The other options miss essential pieces. One focuses on operational tasks like patch management and incident response rather than the full risk calculation workflow. Another lacks asset inventory, risk computation, or a complete view of controls and impacts. The last option omits major elements like threat modeling, vulnerability assessment, and the structured method to compute risk, leaving you without a coherent basis to prioritize mitigations.
