Which of the following best describes confidentiality in information security?

Confidentiality in information security is fundamentally about protecting sensitive information from unauthorized access and ensuring that it is only accessible to individuals who have the appropriate permissions. This principle is essential in maintaining privacy and trust within any organization.

By allowing only authorized users to access information, confidentiality is upheld, ensuring that sensitive data is printed, shared or transmitted securely. It involves implementing controls such as user authentication, access controls, and encryption to safeguard information from exposure.

While ensuring data backups and preventing data destruction are important aspects of information integrity and availability, they do not specifically address the principle of confidentiality. Therefore, the emphasis on authorized access directly aligns with the definition of confidentiality in the context of information security.
