Show answer and explanation
Correct answer: B
Explanation
The CIA triad consists of Confidentiality, Integrity, and Availability. In this scenario, the unauthorized alteration of transaction records violates the Integrity principle, which is responsible for maintaining the accuracy and trustworthiness of data. Integrity ensures that data cannot be modified or tampered with by unauthorized users.
- A. Incorrect.
Confidentiality focuses on ensuring that sensitive information is only accessible to authorized individuals. While important, this is not the aspect affected in this scenario.
- B. Correct.
Integrity ensures that data remains accurate, consistent, and unaltered by unauthorized users. The issue described in the scenario, alteration of transaction records, directly relates to a breach of integrity.
- C. Incorrect.
Availability ensures that systems and data are accessible to authorized users when needed. This scenario does not involve availability concerns.
- D. Incorrect.
Authentication is the process of verifying the identity of users attempting to access a system. While authentication may help mitigate unauthorized access, it is not a part of the CIA triad.
