What term describes the assurance that data is correct and maintained by authorized personnel?

The term that describes the assurance that data is correct and maintained by authorized personnel is integrity. In the context of information security, integrity refers to the accuracy, consistency, and trustworthiness of data over its lifecycle. When integrity is ensured, it implies that the data has not been altered or tampered with by unauthorized individuals and that modifications are conducted strictly by authorized personnel. This is critical for maintaining the reliability and usability of data for decision-making and operations.

Integrity is a fundamental principle of information security, alongside confidentiality and availability. While confidentiality relates to protecting data from unauthorized access, and accessibility deals with ensuring that authorized users can reach the data when needed, integrity specifically focuses on the preservation of the data's accuracy and authenticity. Verification, though related, is more about the process of confirming that data meets certain criteria or standards, rather than a broader concept like integrity that encompasses the overall assurance of data correctness.
