What does classified information refer to?

Classified information refers to sensitive data that is restricted from public access due to its potential to harm national security, the safety of individuals, or the integrity of governmental operations. Such information is often categorized based on its level of sensitivity and the potential damage its disclosure could cause.

This classification system helps to manage and protect information that, if released, could be exploited by adversaries or could undermine the mission of various government entities. Examples of classified information include military secrets, intelligence operations, and certain diplomatic communications that require protection against unauthorized disclosure.

The other choices pertain to types of information that are, by definition, not classified. Publicly accessible data and information that is widely shared or easily accessible do not require the same level of protection and scrutiny, as they do not pose the same risks to national security.
