Which principle of the CIA triad focuses on ensuring that data is accurate, consistent, and trustworthy?

The principle of the CIA triad that focuses on ensuring that data is accurate, consistent, and trustworthy is integrity. Integrity refers to the accuracy and reliability of data throughout its lifecycle. This means that data should not be altered or tampered with in unauthorized ways, ensuring that the information can be trusted by users. Maintaining integrity involves implementing measures such as checksums, hash functions, and data validation processes to prevent corruption or unauthorized changes.

In contrast, confidentiality deals with protecting sensitive information from unauthorized access, while availability ensures that data is accessible to authorized users when needed. Authentication, on the other hand, involves verifying the identity of users who access the system. Each of these principles plays a crucial role in information security, but integrity is specifically about the trust and accuracy of data itself.
