Data Integrity

Noun · Security & Infosec

Definitions

  1. The property that data remains accurate, complete, and unaltered except through authorized, intended changes. In security work, protecting data integrity is as important as protecting confidentiality because bad data can drive bad decisions and unsafe behavior.

    In plain English: Confidence that data has not been wrongly changed or corrupted.

    Example: "The breach did not expose secrets, but it damaged data integrity in the billing tables."
