A records clerk's laptop is encrypted by ransomware. The county clerk cares that sealed case files can no longer be read. Which information-assurance impact is the clerk describing?
Select an answer to reveal the explanation.
Short Explanation
The clerk cannot read the files, and neither should anyone else without authorization — that is confidentiality of civic records, with availability punched too. Changed bits are a side effect, not a reason to call it integrity-only. Incident Review still being up is beside the point.
Full Explanation
Information assurance's CIA triad is applied to the civic data, not to the SIEM. Sealed case files that authorized staff can no longer read, and that an attacker may have rendered unreadable or exposed, are a confidentiality impact; availability is also affected because the records cannot be used. Integrity-only is a common distractor: ciphertext changing bits does not make integrity the clerk's concern. The Incident Review dashboard and CIM identity fields are not the asset in this scenario.
