CRISC Practice Question: A large retailer is implementing a new…
A large retailer is implementing a new point-of-sale (POS) system. The project manager wants to identify risks related to payment card data security. Which risk identification technique would be MOST effective for this purpose?
⚠ Common exam trap
A common mix-up: candidates choose 'Brainstorming session with the project team' because it seems collaborative and proactive, but they fail to recognize that for technical data security risks, a structured, visual analysis like a DFD review is far more precise and complete.
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
✓
Data Flow Diagram (DFD) review
A Data Flow Diagram (DFD) review is most effective because it visually maps how payment card data moves through the POS system—from card swipe to authorization to storage—identifying exactly where data is at rest, in transit, or processed. This allows the team to pinpoint specific PCI DSS control gaps (e.g., unencrypted transmission, unnecessary retention) that other techniques might miss.

Data Flow Diagram (DFD) review
