An assessor emails a spreadsheet labeled Confidential—containing taxpayer identifiers—unencrypted to a personal Gmail account for weekend work. What does this primarily violate?
Select an answer to reveal the explanation.
Short Explanation
Confidential stamped on the file is a stop sign for "email it naked to your weekend inbox." Personal webmail skips the city's encryption, logging, and retention controls. Transmission handling means the path matches the label—approved channels, protected in transit—not convenience routing.
Full Explanation
Classification-driven handling includes secure transmission: approved channels, encryption in transit, and prohibition on sending sensitive data to unauthorized personal accounts. Unencrypted email to consumer mailboxes breaks confidentiality and custody expectations. Organizations typically require secure email, portals, or VPN-backed enterprise storage for Confidential data.
