- A
Confidentiality
- B
Integrity
- C
Availability
- D

Show answer and explanation
Correct answer: A
Explanation
The use of multi-factor authentication is a direct application of the confidentiality principle. It ensures that sensitive data is protected from unauthorized access, which is a fundamental aspect of cybersecurity.
- A. Correct.
Confidentiality involves protecting sensitive information from unauthorized access. By requiring multi-factor authentication, the company ensures that only authorized users can access the financial data, aligning with this principle.
- B. Incorrect.
Integrity refers to ensuring that data remains accurate and unaltered during storage or transmission. While important, this principle is not directly addressed by the use of multi-factor authentication in this scenario.
- C. Incorrect.
Availability ensures that data and systems are accessible when needed. Although critical for security, this principle is not the focus of the scenario provided.
- D. Incorrect.
Non-repudiation ensures that actions or transactions cannot be denied by the party involved. This principle does not directly relate to the use of multi-factor authentication in this case.
