Which principle of the CIA Triad ensures data is not disclosed to unauthorized individuals?

Confidentiality is the principle of the CIA Triad that ensures data is not disclosed to unauthorized individuals. This principle focuses on protecting sensitive information from being accessed by people who do not have the proper permissions. Implementing strong confidentiality measures typically involves using encryption, access controls, and authentication methods to ensure that only authorized users can access specific data.

By maintaining confidentiality, organizations can protect their sensitive information from breaches and prevent unauthorized access that could lead to data theft or loss of privacy. This principle is critical in various contexts, such as protecting personal information, financial data, and proprietary business information.

In the context of the CIA Triad, the other principles—integrity and availability—serve different purposes. Integrity ensures that data remains accurate and unaltered, while availability ensures that authorized users have access to data when needed. Authentication, while related to access control, specifically verifies user identities but does not directly address the fundamental aspect of protecting data from unauthorized disclosure.
