In information security, which concept is traditionally emphasized as protecting data from unauthorized disclosure?

• A. Confidentiality
• B. Integrity
• C. Availability
• D. Authenticity - Non-Repudiation (use digital signatures)

Answer: (A)

Confidentiality is the practice of keeping information secret from anyone who is not authorized to see it. In the common security framework known as the CIA triad, confidentiality focuses on preventing unauthorized disclosure, while integrity ensures data remains accurate and unchanged, and availability ensures data and services are accessible when needed. The emphasis on confidentiality reflects the goal of protecting sensitive data from leaks or exposure, using methods such as encryption, strict access controls, authentication, and the principle of least privilege. Authenticity and non-repudiation deal with verifying identities and ensuring actions cannot be denied, which address different security concerns and do not directly target preventing disclosure.
