Which sensitivity level indicates the highest risk to national security?

The sensitivity level that indicates the highest risk to national security is the Special-Sensitive classification. This designation is associated with information that, if disclosed, could cause exceptionally grave damage to national security interests. Special-Sensitive materials typically include sensitive intelligence operations, nuclear secrets, or other critical government functions that require stringent safeguarding measures.

The classification system is designed to prioritize the protection of information based on its potential impact on national security. Within this framework, the Special-Sensitive category is reserved for information of such significance that it necessitates the highest level of security clearance and oversight. This classification ensures that access is tightly controlled and that only individuals with the requisite trustworthiness and need-to-know are granted access to this highly sensitive information.
