What are the three classification levels of information under NISP?

The three classification levels of information under the National Industrial Security Program (NISP) are Confidential, Secret, and Top Secret. This classification system is established to protect national security information based on the level of potential damage that unauthorized disclosure could cause to national security.

Confidential information is the lowest classification level and is deemed to require protection because unauthorized disclosure could cause damage to national security. Secret information represents a higher level of sensitivity, where unauthorized disclosure could cause serious damage to national security. Top Secret information is the highest classification, which, if disclosed without authorization, could cause exceptionally grave damage to national security.

Understanding these classifications is crucial for Facility Security Officers as they implement security measures and ensure compliance with regulations regarding the handling, storage, and transmission of classified information. This hierarchical structure helps to maintain national security by clearly delineating the sensitivity of different types of information, allowing for appropriate protective measures to be taken.
