What principle is designed to prevent unauthorized disclosure of information?

The principle that is designed to prevent unauthorized disclosure of information is confidentiality. This principle focuses on ensuring that sensitive information is accessed only by those individuals who are authorized to view it. Confidentiality is critical in protecting data from unauthorized access and breaches, thereby maintaining the privacy and security of the information.

When implementing confidentiality measures, organizations typically use techniques such as encryption, access controls, and user authentication. These methods help to ensure that only authorized users can access confidential data, thus preventing its disclosure to unauthorized parties.

In the context of cybersecurity, maintaining confidentiality is essential for safeguarding personal data, trade secrets, and other sensitive information from being exposed or misused. While integrity refers to the accuracy and trustworthiness of data, availability pertains to ensuring that information is accessible to authorized users when needed, and accountability involves tracing actions to individuals to ensure responsible handling of information, none of these principles directly address the prevention of unauthorized disclosure as explicitly as confidentiality does.
