問題文
During a stage 2 audit of a hosting provider, an auditor finds that a nightly export of customer records was written to a folder that every employee could open. The records themselves were unchanged and the service stayed reachable throughout. Which property of the information was lost?
選択肢
- Availability, because the users outside the affected office lost the shared folder and missed the exported material.
- Integrity, because the values outside the originating source changed the stored records and lost the earlier correctness.
- Accountability, because the origin outside the recorded export escaped the audit trace and hid the earlier author.
- Confidentiality, because the staff outside the entrusted grouping opened the shared directory and read the exported columns.
