How is “confidential information” defined?

The definition of "confidential information" is accurately described as sensitive data that should not be disclosed. This type of information often pertains to personal, proprietary, or classified material that requires protection to maintain privacy and security. Organizations implement confidentiality protocols to prevent unauthorized access or sharing of such information, emphasizing the importance of discretion and trust in various professional settings. This ensures that sensitive details, whether related to individuals, companies, or national security, remain secure and are only accessible to those with the proper clearance or need to know.

The other options do not align with the concept of confidentiality. Information available to everyone, data that can be shared without limitations, and public information are all open to access, contrasting the essence of confidentiality, which is about restriction and protection of sensitive details.
