Which of the following is NOT approved for storing TOP SECRET information (with supplemental controls)?

• A. Six-sided steel cabinet
• B. GSA-approved container
• C. Open storage area
• D. Vault

Answer: (A)

Storing TOP SECRET information with supplemental controls must use an approved security container or vault that meets established standards. A six-sided steel cabinet does not qualify as an approved security container for TOP SECRET, even with added measures. It isn’t certified to meet the security requirements set for TOP SECRET storage, so it cannot be used under those rules. In contrast, a GSA-approved container is specifically certified for TOP SECRET storage with supplemental controls, and a vault provides the level of security required by the policy. An open storage area, lacking any physical security, is not permitted for TOP SECRET information.
