In the context of the CIA triad, what has been compromised if a user can alter the price of an item on an e-commerce site?

The correct choice highlights a fundamental aspect of the CIA triad, which consists of Confidentiality, Integrity, and Availability, key principles in information security. When a user is able to alter the price of an item on an e-commerce site, it directly impacts the integrity of the data on that platform.

Integrity refers to the accuracy and trustworthiness of data. When a user can change information without proper authorization, such as modifying prices, it undermines the integrity of that data. This creates significant issues, as customers might be misled about the true costs of items, potentially leading to financial losses or a breach of trust in the e-commerce platform.

In this scenario, although confidentiality, availability, and authentication are crucial elements of security, they are not compromised by the act of altering a price. Confidentiality deals with the protection of information from unauthorized access, availability ensures that data and resources are accessible when needed, and authentication involves verifying the identity of users. However, the situation described is primarily about a breach of integrity, making that the main concern in this instance.
