What is the primary purpose of marking special categories of classified information?

The primary purpose of marking special categories of classified information is to properly identify and protect sensitive information. Marking is an essential process that ensures that individuals handling, accessing, or interpreting classified information can readily recognize its sensitivity and the specific handling requirements associated with it. This includes indicating the classification level, such as Confidential, Secret, or Top Secret, as well as any special caveats that may apply.

By marking information appropriately, it reduces the risk of unauthorized disclosure or misuse and ensures that proper security measures are implemented. This is vital for maintaining national security and protecting sensitive data from potential threats. It also facilitates compliance with legal and regulatory requirements related to the management of classified information, ensuring that all personnel understand their responsibilities and obligations in handling such data.
