Modifying important or sensitive information is categorized under which principle?

The principle related to modifying important or sensitive information is integrity. Integrity refers to the accuracy and completeness of data and ensuring that information is not altered or tampered with unauthorized. When you modify data, you are directly affecting its integrity.

For instance, in a cybersecurity context, maintaining data integrity means that any change made to the data must be authorized, logged, and verifiable. This is crucial in scenarios such as financial transactions, medical records, or any sensitive information that, if altered incorrectly, could cause significant harm or misrepresentation.

In contrast, confidentiality pertains to keeping information secret and ensuring that unauthorized individuals cannot access it, while availability is about ensuring that information is accessible when needed. Both of these principles are essential in cybersecurity but specifically do not address the modification aspect of data.
