CRISC Information Technology and Security Practice Question
A manufacturing company is connecting its industrial control systems (ICS) to the corporate network for real-time data analytics. What is the most significant risk arising from this IT/OT convergence?
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 from IT to OT systems
Connecting OT to IT networks exposes ICS to threats from the corporate network, expanding the attack surface and potentially allowing attackers to pivot to OT systems.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Reduced network bandwidth for OT operations
Why it's wrong here
Bandwidth is a performance issue, not the most significant security risk.
- ✓
Expanded attack surface from IT to OT systems
Why this is correct
The convergence creates new paths for attackers to reach OT systems.
- ✗
Increased data storage costs
Why it's wrong here
Storage cost is a financial concern, not a primary security risk.
- ✗
Loss of proprietary control protocols
Why it's wrong here
Protocols may be exposed but the main risk is the expanded attack surface.
