Question 810
At Oceanview Payments, a team reports that it corrected the following problem affecting regulated payments and credentialed access: A third-party prompt asks an enterprise AI assistant to disclose internal secrets through browser upload. Which observation BEST verifies that the correction actually worked?
Explanation
Correct Answer
An exfiltration simulation fails and produces a reviewable security event. This is the decisive evidence for the original problem: A third-party prompt asks an enterprise AI assistant to disclose internal secrets through browser upload. It verifies that the intended corrective control—Enforce trusted authorization and AI guardrails together with outbound data inspection—works in the relevant environment; a completed change ticket alone would not prove the outcome at Oceanview Payments.
Incorrect Answers
Analysts can justify an incident from safe metadata and approved uploads are no longer blocked. This would be relevant evidence for a different failure: DLP blocks legitimate encrypted uploads without showing analysts which sensitive pattern matched, usually addressed by Tune policy classification, severity, and event visibility without exposing protected content unnecessarily. It does not demonstrate that the current problem at Oceanview Payments was resolved. The specific required evidence is: An exfiltration simulation fails and produces a reviewable security event.
Approved AI usage meets policy without transmitting protected information. This would be relevant evidence for a different failure: A security team bans every AI destination rather than applying risk-based safeguards for approved work, usually addressed by Define AI use policies with destination trust, content controls, and monitoring appropriate to risk. It does not demonstrate that the current problem at Oceanview Payments was resolved. The specific required evidence is: An exfiltration simulation fails and produces a reviewable security event.
A prohibited data transfer is stopped even when the destination is otherwise allowed. This would be relevant evidence for a different failure: A secure Internet gateway has DLP rules but exceptions are so broad that personal information leaves through approved sites, usually addressed by Narrow exceptions to specific users, destinations, and justified content classifications. It does not demonstrate that the current problem at Oceanview Payments was resolved. The specific required evidence is: An exfiltration simulation fails and produces a reviewable security event.
