What is required to be done after an emergency opening of a COMSEC container?

• A. Notify all personnel
• B. Complete an inventory and change the combination
• C. Re-assign access permissions
• D. Lock the container without inspection

Answer: (B)

After an emergency opening of a COMSEC container, it is crucial to complete an inventory and change the combination. This action ensures that any changes in the access to the classified material are documented, and it secures the integrity and safety of the items within. An inventory allows personnel to account for all classified items, confirming that nothing is lost or unauthorized. Changing the combination prevents anyone who may have had unauthorized access during the emergency from subsequently accessing the container. This practice aligns with the principles of safeguarding classified information and maintaining COMSEC protocols, ensuring that sensitive material is protected from potential breaches.
