GRID GRID ICS Vulnerability Management and Risk Assessment

Question 1

Which framework is most commonly used to assess and prioritize vulnerabilities in industrial control system environments?

Accepted Answer

CVSS

Answer

CVSS (Common Vulnerability Scoring System) provides a standardized method to rate the severity of ICS vulnerabilities and prioritize remediation.

Question 2

What is the primary challenge of applying traditional IT patch management practices to OT/ICS environments?

Accepted Answer

OT systems often cannot tolerate downtime required for patching

Answer

OT/ICS systems frequently run 24/7 critical processes where the downtime needed for patching can cause operational disruptions or safety incidents.

Question 3

Which ICS-specific vulnerability database provides advisories specifically for industrial control systems?

Accepted Answer

ICS-CERT CISA advisories

Answer

CISA ICS-CERT publishes dedicated advisories for vulnerabilities affecting industrial control system products and protocols.

Question 4

In ICS risk assessment, what does the term 'consequence severity' most directly refer to?

Accepted Answer

The potential physical, safety, or operational impact if a vulnerability is exploited

Answer

Consequence severity in ICS risk assessment captures the physical harm, safety hazards, or operational disruption that could result from successful exploitation.

Question 5

What compensating control is commonly used when an ICS component cannot be patched due to operational constraints?

Accepted Answer

Network segmentation and enhanced monitoring

Answer

When patching is not feasible, network segmentation isolates the vulnerable component while enhanced monitoring detects exploitation attempts.
