Question 240
At Alpine Healthcare, the clinical database operations team maintains a hybrid healthcare scheduling and records platform with requirements for patient confidentiality and high service availability. The acceptance review requires independent evidence for: A reporting application gives all users full employee rows and uses dynamic data masking as its only authorization boundary. Which observed result BEST proves the intended problem is corrected?
Explanation
Correct Answer
An unauthorized identity is denied the restricted rows rather than simply seeing partially masked values. That observable result supports resolution of: A reporting application gives all users full employee rows and uses dynamic data masking as its only authorization boundary. The corresponding corrective change is: Use real SQL permissions or row-level security for access enforcement and treat dynamic data masking only as presentation obfuscation. The Alpine Healthcare reviewer can distinguish demonstrated database behavior from an untested change claim.
Incorrect Answers
A least-privilege support identity sees the intended masked values and the authorized privileged user sees full values. That result is evidence for another corrective change: Configure suitable dynamic data masking for designated columns while separately enforcing underlying object and row permissions. The alternative problem is: A support operator needs limited display of customer email addresses but current queries show the full address and no masking policy exists. The current Alpine Healthcare issue is instead: A reporting application gives all users full employee rows and uses dynamic data masking as its only authorization boundary. Its decisive acceptance evidence would be: An unauthorized identity is denied the restricted rows rather than simply seeing partially masked values.
A control change produces an audit record that remains available even if the originating database administrator account is disabled. That result is evidence for another corrective change: Stream SQL audit events to a protected independent storage or monitoring destination with retention and administrative separation. The alternative problem is: An audit design stores logs only on the production database server so administrators could remove evidence during the incident being investigated. The current Alpine Healthcare issue is instead: A reporting application gives all users full employee rows and uses dynamic data masking as its only authorization boundary. Its decisive acceptance evidence would be: An unauthorized identity is denied the restricted rows rather than simply seeing partially masked values.
A controlled tenant-A session cannot retrieve tenant-B rows even when it submits an unrestricted SELECT query. That result is evidence for another corrective change: Implement row-level security with an appropriate predicate tied to trusted session or identity context. The alternative problem is: A multi-tenant database returns records from other customers because the application relies only on a WHERE tenant_id clause supplied by the caller. The current Alpine Healthcare issue is instead: A reporting application gives all users full employee rows and uses dynamic data masking as its only authorization boundary. Its decisive acceptance evidence would be: An unauthorized identity is denied the restricted rows rather than simply seeing partially masked values.
