CRISC Practice Question: A risk manager is evaluating the risk associated…
A risk manager is evaluating the risk associated with a new third-party vendor that will have access to customer data. The vendor has been in business for 10 years and holds ISO 27001 certification. Which factor should be given the MOST weight when determining the vendor's risk level?
⚠ Common exam trap
The trap here is that candidates overvalue certifications and tenure as proxies for security, while the CRISC exam emphasizes that risk is fundamentally tied to the asset's value and exposure, not just the vendor's credentials.
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
✓
The sensitivity and volume of data the vendor will access.
The sensitivity and volume of data directly determine the potential impact of a breach, which is a core component of inherent risk. Even with strong controls like ISO 27001, the risk level is primarily driven by the value and quantity of the asset at risk (customer data). In IT risk assessment, the asset's criticality and exposure outweigh historical or certification-based indicators when calculating residual 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.
- ✗
The vendor's years in operation.
Why it's wrong here
Longevity indicates stability, not current security posture; a ten-year-old vendor may still have unpatched systems or weak access controls over customer data. Years in operation matter when assessing financial viability or continuity, not when determining the risk exposure created by data access.
- ✗
The vendor's ISO 27001 certification.
Why it's wrong here
ISO 27001 certifies that a management system exists, not the effectiveness of controls protecting these specific customer data flows, so it cannot carry the most weight. Certification is genuinely valuable as an independent assurance artefact when assessing a vendor's overall control maturity during due diligence.
- ✓
The sensitivity and volume of data the vendor will access.
Why this is correct
Risk severity is driven primarily by the data itself: highly sensitive, high-volume customer data creates greater potential impact if breached. ISO 27001 certification and vendor longevity are assurance factors, but they cannot reduce the inherent risk posed by the data the vendor accesses.
- ✗
The contractual terms for data protection.
Why it's wrong here
Contractual terms define obligations after signing but do not measure the vendor's actual likelihood of experiencing a breach, which is what risk level assesses. Contracts are the correct focus when the question concerns allocating liability or enforcing remedies rather than evaluating inherent vendor risk.
