CRISC Information Technology and Security Practice Question
An organization is deploying a large number of Internet of Things (IoT) sensors for environmental monitoring in a remote facility. The sensors have limited processing power and cannot be patched easily. Which risk should the risk manager prioritize?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Expanded attack surface with unpatched devices
IoT devices often lack security updates, making them vulnerable to exploitation. The expanded attack surface from many devices compounds this risk.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Vendor lock-in to proprietary protocols
Why it's wrong here
Vendor lock-in is a procurement risk, not the most critical security risk.
- ✓
Expanded attack surface with unpatched devices
Why this is correct
Correct. Many unpatched IoT devices create a large attack surface.
- ✗
Insufficient bandwidth for data transmission
Why it's wrong here
Bandwidth is a capacity issue, not a security risk.
- ✗
Data integrity issues from sensor malfunction
Why it's wrong here
While possible, the primary risk is security due to unpatched vulnerabilities.
