Which type of information includes both personal and business information and is not readily available?

Confidential information encompasses both personal and business information, which is not readily available to the public and is protected due to its sensitive nature. This type of information is typically restricted to authorized individuals or entities to maintain privacy, security, and compliance with regulations. For instance, personal identifiers or proprietary business strategies fall under this category, highlighting the importance of safeguarding such data.

In contrast, public information is readily available and can be accessed by anyone without restrictions, while accessible information does not imply any sensitivity and can typically be obtained easily. Legacy information usually refers to data from outdated systems or older forms of information management but does not necessarily cover the aspects of confidentiality regarding personal or business data. Therefore, the selection of confidential information is justified based on its protective requirements and the sensitive nature of the data involved.
