CRISC Information Technology and Security Practice Question
An organization is deploying IoT devices for environmental monitoring in a manufacturing facility. Which THREE of the following are significant security risks that should be addressed? (Select THREE.)
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 due to numerous connected devices
IoT devices significantly expand the attack surface due to their sheer number and network connectivity (option A). They often lack mechanisms for firmware updates, leaving them vulnerable to unpatched exploits (option C). Additionally, many IoT devices use legacy components with known vulnerabilities that cannot be easily remediated (option E). Options B and D are not considered primary security risks: vendor lock-in is a business risk, and data sovereignty is less critical for non-sensitive environmental data.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Expanded attack surface due to numerous connected devices
Why this is correct
More devices mean more entry points.
- ✗
Vendor lock-in due to proprietary protocols
Why it's wrong here
Vendor lock-in is not a security risk.
- ✓
Lack of firmware update capabilities for security patches
Why this is correct
Unpatched devices are vulnerable.
- ✗
Data sovereignty issues for sensor data
Why it's wrong here
Environmental monitoring data typically lacks sensitivity.
- ✓
Use of legacy components with known vulnerabilities
Why this is correct
Legacy components often have unpatched flaws.
