The most important consideration when performing a vendor risk assessment is the inherent risk of the business process supported by the vendor, which is the risk that exists before any controls or mitigating factors are applied. The inherent risk reflects the potential impact and likelihood of the vendor’s failure or disruption on the enterprise’s objectives, operations, and reputation. The higher the inherent risk, the more rigorous and frequent the vendor risk assessment should be. The results of the last risk assessment of the vendor, the risk tolerance of the vendor, and the length of time since the last risk assessment of the vendor are not the most important considerations, as they do not directly measure the level of exposure and dependency that the enterprise has on the vendor. References = CRISC Certified in Risk and Information Systems Control – Question204; ISACA Certified in Risk and Information Systems Control (CRISC) Certification Exam Question and Answers, question 204.
