Question 30

Confidentiality

Confidentiality is the principle of the CIA triad that is supported in this context, as it emphasizes the protection of sensitive information from unauthorized access and disclosure.

A) Confidentiality

This option is correct because confidentiality focuses on ensuring that sensitive data is only accessible to authorized individuals. It plays a crucial role in maintaining privacy and safeguarding information against unauthorized access, which aligns with the core concept being tested.

B) Availability

This option is incorrect as availability refers to ensuring that information and resources are accessible to authorized users when needed. While important, it does not relate directly to the protection of sensitive information from unauthorized access, which is the focus of the question.

C) Integrity

This option is also incorrect. Integrity involves maintaining the accuracy and consistency of data over its lifecycle, ensuring that it remains unaltered except by authorized users. While important for data security, it does not pertain to the concept of controlling access to sensitive information.

D) Authentication

This option is incorrect as authentication is the process of verifying the identity of a user or system before granting access to resources. Although it supports confidentiality, it does not directly address the principle itself, which is primarily about protecting information from unauthorized access.

Conclusion

Confidentiality is the definitive principle supported in this context as it directly addresses the need to protect sensitive information from unauthorized access. Options B, C, and D, while important aspects of information security, do not focus specifically on the protection of privacy, making them less relevant to the question posed.
