Data confidentiality is maintained when only those people who are authorized to access the information is allowed and unauthorized access is prevented.
Information integrity prevents data from being improperly modified, either by accident or maliciously. When data integrity is held, the information is non-reputable, which ensures that the authenticity cannot be challenged.
