The situation described relates to a change in the price of a book from $19.99 to $1.99, which suggests that the data related to the price has been altered. This alteration impacts the accuracy and trustworthiness of the information.
In the context of the CIA triad (Confidentiality, Integrity, Availability):
- Confidentiality refers to ensuring that information is accessible only to those authorized to have access. This situation doesn’t specifically involve unauthorized access to sensitive information.
- Integrity involves maintaining the accuracy and reliability of data. The unauthorized change of the book price directly relates to a breach of integrity, as the price information has been altered incorrectly or without authorization.
- Availability pertains to ensuring that authorized users have access to information when needed. This situation does not suggest an issue with access to the data.
Given the scenario, the part of the CIA triad that has been broken is Integrity.
