What is the procedure for reporting lost keying/classified material?

Notifying the custodian or the security manager is the correct procedure for reporting lost keying or classified material because these individuals are responsible for overseeing the custody and safeguarding of classified information within their unit or organization. When keying material is missing, it is crucial to alert those with the appropriate authority and knowledge to initiate the necessary protocols for loss mitigation, damage control, and potentially securing further sensitive information.

The custodian or security manager can then assess the situation, determine the appropriate next steps, and ensure that all required reports are filed and procedures followed in accordance with security regulations. Acting quickly by notifying these authorities helps to minimize potential security breaches and safeguard the integrity of critical information.

While reporting to the commanding officer, filling out an incident report, or informing fellow personnel may be part of the broader process, the immediate responsibility rests with the custodian or security manager, who is specially trained to handle such incidents.
