Which factor relates to preventing unauthorized destruction and alteration of data in NIST standards?

The correct choice is integrity, as it directly pertains to ensuring that data remains accurate, reliable, and unaltered unless authorized. In the context of NIST standards, integrity involves mechanisms that protect information from being improperly modified or destroyed. This includes implementing controls, processes, and practices that enforce the accuracy of the data throughout its lifecycle.

Integrity is crucial because it assures users and systems that the information they access has not been tampered with and that it accurately reflects the intended information. This helps maintain trust in the data's validity and supports informed decision-making based on that data.

Other factors, while important, do not specifically address the prevention of unauthorized changes to data. For instance, confidentiality focuses on protecting data from unauthorized access, availability ensures that the data is accessible when needed, and compliance relates to adherence to laws and regulations rather than the specific preservation of data integrity.
