What specifically does Confidentiality protect within the CIA context?

In the context of the CIA triad, which stands for Confidentiality, Integrity, and Availability, confidentiality specifically focuses on protecting information from unauthorized access. This means ensuring that sensitive data is only accessible to individuals who have the proper authorization. By maintaining confidentiality, organizations can safeguard personal information, trade secrets, and any other types of data that could cause harm if disclosed to those without the right to see it.

The other options relate to different aspects of data security. For instance, data from system failures pertains more to availability, while protecting against corruption is related to integrity. Likewise, prevention of data loss falls under availability as well, ensuring that data remains accessible when needed. Confidentiality is distinct in its emphasis on preventing unauthorized individuals or entities from accessing sensitive information. Thus, the core focus of confidentiality is accurately represented by the option that emphasizes the protection from unauthorized access.
