What are the key elements of a comprehensive OT vulnerability management program?

• A. Occasional manual checks
• B. Asset discovery, ongoing scanning, risk scoring, patch/testing, change control, verification, and governance reporting
• C. Patch only after outage
• D. No governance

Answer: (B)

A comprehensive OT vulnerability management program hinges on a continuous, risk-based lifecycle that covers visibility, detection, prioritization, safe remediation, and oversight. Asset discovery ensures you know every device and asset on the network, which is essential in OT where many devices are legacy or hard to inventory. Ongoing scanning keeps vulnerabilities current rather than relying on occasional checks. Risk scoring helps focus limited resources on the most impactful issues, balancing security with the need to maintain uptime. Patch and testing practices are crucial because OT environments require validated changes to avoid disrupting control systems or safety functions. Change control governs any modification, preventing unintended outages and configuration drift. Verification confirms that remediation actually closed the vulnerability and didn’t introduce new risks. Governance reporting provides leadership with visibility into progress, compliance, and trends, enabling accountability and continuous improvement. Without this full spectrum, you’d risk blind spots, delayed remediation, unsafe or incompatible patches, and unmanaged risk. The other options fail to provide continuous visibility, timely and safe remediation, or proper oversight and governance.
