Unauthorized disclosure and loss of privacy is a lapse in which security attribute?

The correct answer is confidentiality, which refers to the protection of information from unauthorized access and disclosure. When confidentiality is compromised, there can be unauthorized disclosure of sensitive or private information, leading to a loss of privacy for individuals or organizations. This attribute ensures that only authorized personnel have access to specific data and that sensitive information remains protected. Therefore, when discussing lapses in security that lead to unauthorized disclosure, confidentiality is the key attribute that is being violated.

Integrity, on the other hand, relates to the accuracy and consistency of data, ensuring that it has not been altered or tampered with. Availability ensures that information is accessible and usable upon demand by authorized users. Authentication confirms the identity of users, ensuring that they have the rights and permissions to access certain data. While these attributes are critical to overall security, the protection of privacy specifically corresponds to confidentiality.
