CRISC Information Technology and Security Practice Question
An organization is deploying a large number of IoT sensors in a smart building project. The sensors are from multiple vendors and some have limited firmware update capabilities. Which of the following risks should be the PRIMARY concern for the risk manager?
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
✓
Inability to patch vulnerabilities in legacy IoT devices
IoT devices with limited firmware update capabilities create a long-term vulnerability, as they cannot be patched against newly discovered flaws. This expands the attack surface and increases risk over time.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Data sovereignty of sensor data stored in the cloud
Why it's wrong here
Data sovereignty is important but secondary to the inability to secure devices.
- ✓
Inability to patch vulnerabilities in legacy IoT devices
Why this is correct
Unpatchable devices pose a persistent security risk that cannot be easily mitigated.
- ✗
Interoperability issues between different sensor protocols
Why it's wrong here
Interoperability is an operational concern, not a primary security risk.
- ✗
High energy consumption of sensors
Why it's wrong here
Energy consumption is a maintenance issue.
