Which of the following best describes the goal of the confidentiality principle in classified information?

The goal of the confidentiality principle in classified information is fundamentally aimed at preventing unauthorized access to sensitive information. This principle is crucial because it safeguards national security and protects the interests of individuals and entities involved. By ensuring that only those who have the appropriate clearance and a legitimate need to know can access certain classified materials, the confidentiality principle effectively minimizes the risk of sensitive data being disclosed to individuals or groups that could misuse it.

In the context of national security, unauthorized access can lead to grave consequences, including compromised operations, risk to lives, and the potential for strategic advantages to be lost. Thus, implementing strict measures to maintain confidentiality is vital for protecting classified information and maintaining the integrity of governmental operations.

The other options do not align as closely with the primary aim of confidentiality in classified contexts, which solidifies the importance of restricted access as a protective measure rather than a means of efficiency, sharing, or public disclosure.
