What is a critical step before transmitting classified information?

Confirming the classification level is indeed a critical step before transmitting classified information. This involves ensuring that the information is accurately marked with the appropriate classification, which dictates how the information can be handled and shared. It is essential because transmitting information that is not properly classified can lead to the exposure of sensitive material, violate protocols, and potentially endanger national security.

All individuals involved in the transmission process must confirm both their own authority to handle that specific level of classified information and the classification status of the information itself. This helps maintain the integrity of the classification system and ensures that only authorized personnel have access to sensitive information.

While encrypting the information, securing the transmission line, and informing the recipient are all important components of the overall process of transmitting classified information, they should only take place after the classification level has been confirmed. Without this confirmation, the risk associated with transmitting classified information increases significantly.
