Which of the following classifications is NOT considered a type of classified information?

The classification of information typically falls into three primary categories: Confidential, Secret, and Top Secret. These classifications are used to denote the level of sensitivity of the information and the potential damage that could result from its unauthorized disclosure.

Confidential information might cause damage to national security if disclosed, Secret information could cause serious damage, and Top Secret information would cause exceptionally grave damage if it were made public. Each of these classifications involves strict protocols for handling, access, and dissemination.

On the other hand, Public information is not classified. It is available for general access and does not require any special permissions for dissemination. This distinction is crucial because it highlights that Public information does not fall under the protective measures of classified data. Therefore, in the context of the classifications being referenced, Public is correctly identified as the type of information that is not classified at all.
