What aspect of the CIA triad focuses on the prevention of unauthorized access to sensitive data?

The aspect of the CIA triad that focuses on the prevention of unauthorized access to sensitive data is confidentiality. Confidentiality refers to the assurance that information is not disclosed to unauthorized individuals or entities, ensuring that sensitive data remains private and secure. This principle is critical for safeguarding personal information, financial data, and any other type of sensitive information that organizations may handle.

To achieve confidentiality, organizations often implement access controls, encryption, and other security measures that restrict who can view or access certain information. This ensures that even if data is stored or transmitted, it remains confidential and only accessible to those who have received explicit permission to do so.

Other concepts within the CIA triad play important roles but do not specifically address unauthorized access in the same way. For example, integrity relates to maintaining the accuracy and reliability of data, while availability ensures that authorized users can access information when needed. Authenticity, although crucial in confirming the identities of users or sources, is not directly related to unauthorized access.
