• A. True
• B. False
• C. Only applies to sensitive data
• D. Not applicable to all data types

Answer: (A)

Data integrity is a fundamental principle in information security that ensures accuracy and consistency of data over its entire lifecycle. The assertion that data integrity ensures information is altered only with proper authorization is true because it highlights the importance of controlling who has access to modify data. When data integrity is maintained, it means that any changes made to data are legitimate and authorized by appropriate personnel, which helps in protecting against unauthorized alterations that could compromise the reliability of the information.

This principle is crucial in various contexts, from maintaining the integrity of sensitive information, such as personal data or financial records, to ensuring the accuracy of less sensitive data. Proper authorization mechanisms, such as access controls and authentication processes, are fundamental to upholding data integrity. Therefore, the statement aligns with the core tenets of data integrity in privacy and security practices.
