What is the primary distinction between classified and unclassified information?

The primary distinction between classified and unclassified information lies in the required protection measures for classified information. Classified information is designated as sensitive due to the potential harm that its unauthorized disclosure could cause to national security or other significant interests. As a result, it is subject to stringent access controls, handling procedures, and protective measures.

Unclassified information, on the other hand, does not pose a risk to national security if disclosed. Therefore, it does not require the same level of protection and can be shared more freely among individuals who may or may not have a security clearance. This fundamental difference emphasizes the importance of safeguarding classified information while permitting broader access and usage of unclassified content.
